What are the steps for an Exchange certificate renewal?

An expired Exchange certificate can bring your messaging platform to a halt, but it’s easy enough to check and replace the expired certificate.

When mail stops flowing, Outlook access breaks and the Exchange Management Console/Shell gives errors, then it might be time to see if an Exchange certificate renewal is in order.

Exchange adds a certificate by default with your protocols during its installation, including Simple Mail Transfer Protocol and Internet Information Services (IIS). Many companies do not allow access to Outlook on the web, so mail is only accessible internally. This limits the Exchange Server capabilities as Microsoft designed it to be accessible from anywhere on any device.

For companies that choose to limit Exchange’s functionality, the IT staff often opts to use the default certificate, which has a five-year life span. In five years, IT might forget about the Exchange certificate renewal until they receive countdown emails warning that it will expire. If nobody sees these emails and the certificate expires, then problems will start, as Exchange services that require a valid certificate might not work.

To check a certificate’s status, run the following PowerShell command:

Get-ExchangeCertificate | fl

Assign a new certificate for Exchange 2010

If Exchange breaks due to an expired certificate, then you might want to push for a quick fix by issuing a certificate to an internal certificate authority. This won’t work because the certificate authority will not sign the certificate.

If you start to panic as help desk tickets start to flood in, this is when trouble typically happens. You might try to adjust the settings in IIS, but this can break Exchange. However, the fix is simple.

Run the New-ExchangeCertificate command to initiate the Exchange certificate renewal process. This PowerShell cmdlet will create a new self-signed certificate for Exchange 2010. The command prompts you to replace the existing certificate. Click Yes to proceed.

Exchange certificate replacement
Execute the PowerShell New-ExchangeCertificate cmdlet to build a new self-signed certificate for Exchange 2010.

Next, assign the services from the old certificate to the new one and perform an IISReset from an elevated command prompt to get Exchange services running again.

Finally, ensure the bindings in IIS are set to use the new certificate.

Learn the tricks for using Microsoft Teams with Exchange

Using Microsoft Teams means Exchange administrators need to understand how this emerging collaboration service connects to the Exchange Online and Exchange on-premises systems.

At its 2017 Ignite conference, Microsoft unveiled its intelligent communications plan, which mapped out the movement of features from Skype for Business to Microsoft Teams, the Office 365 team collaboration service launched in March 2017. Since that September 2017 conference, Microsoft has added meetings and calling features to Teams, while also enhancing the product’s overall functionality.

Organizations that run Exchange need to understand how Microsoft Teams relies on Office 365 Groups, as well as the setup considerations Exchange administrators need to know.

How Microsoft Teams depends on Office 365 Groups

Each team in Microsoft Teams depends on the functionality provided by Office 365 Groups, such as shared mailboxes or SharePoint Online team sites. An organization can permit all users to create a team and Office 365 Group, or it can limit this ability by group membership. 

When creating a new team, it can be linked to an existing Office 365 Group; otherwise, a new group will be created.

Microsoft Teams layout
Microsoft Teams is Microsoft’s foray into the team collaboration space. Using Microsoft Teams with Exchange will require administrators to stay abreast of roadmap plans for proper configuration and utilization of the collaboration offering.

Microsoft adjusted settings recently so new Office 365 Groups created by Microsoft Teams do not appear in Outlook by default. If administrators want new groups to show in Outlook, they can use the Set-UnifiedGroup PowerShell command.

Microsoft Teams’ reliance on Office 365 Groups affects organizations that run an Exchange hybrid configuration. In this scenario, the Azure AD Connect group writeback feature can be enabled to synchronize Office 365 Groups to Exchange on premises as distribution groups. But this setting could lead to the creation of many Office 365 Groups created via Microsoft Teams that will appear in Exchange on premises. Administrators will need to watch this to see if the configuration will need to be adjusted.

Using Microsoft Teams with Exchange Online vs. Exchange on premises

As an Exchange Online customer, subscribers also get access to all the Microsoft Teams features. However, if the organization uses Exchange on premises, then certain functionality, such as the ability to modify user profile pictures and add connectors, is not available.

Microsoft Teams’ reliance on Office 365 Groups affects organizations that run an Exchange hybrid configuration.

Without connectors, users cannot plug third-party systems into Microsoft Teams; certain add-ins, like the Twitter connector that delivers tweets into a Microsoft Teams channel, cannot be used. Additionally, organizations that use Microsoft Teams with Exchange on-premises mailboxes must run on Exchange 2016 cumulative update 3 or higher to create and view meetings in Microsoft Teams.

Message hygiene services and Microsoft Teams

Antispam technology might need to be adjusted due to some Microsoft Teams and Exchange integration issues.

When a new member joins a team, the email.teams.microsoft.com domain sends an email to the new member. Microsoft owns this domain name, which the tenant administrator cannot adjust.

Because the domain is considered an external email domain to the organization’s Exchange Online deployment, the organization’s antispam configuration in Exchange Online Protection may mark the notification email as spam. Consequently, the new member might not receive the email or may not see it if it goes into the junk email folder.

To prevent this situation, Microsoft recommends adding email.teams.microsoft.com to the allowed domains list in Exchange Online Protection.

Complications with security and compliance tools

Administrators need to understand the security and compliance functionality when using Microsoft Teams with Exchange Online or Exchange on premises. Office 365 copies team channel conversations in the Office 365 Groups shared mailbox in Exchange Online so its security and compliance tools, such as eDiscovery, can examine the content. However, Office 365 stores copies of chat conversations in the users’ Exchange Online mailboxes, not the shared mailbox in Office 365 Groups.

Historically, Office 365 security and compliance tools could not access conversation content in an Exchange on-premises mailbox in a hybrid environment. Microsoft made changes to support this scenario, but customers must request this feature via Microsoft support.

Configure Exchange to send email to Microsoft Teams

An organization might want its users to have the ability to send email messages from Exchange Online or Exchange on premises to channels in Microsoft Teams. To send an email message to a channel, users need the channel’s email address and permission from the administrator. A right-click on a channel reveals the Get email address option. All the channels have a unique email address.

Administrators can restrict the domains permitted to send email to a channel in the Teams administrator settings in the new Microsoft Teams and Skype for Business admin center.

Plan your Exchange migration to Office 365 with confidence

Introduction

Choosing an Exchange migration to Office 365 is just the beginning of this process for administrators. Migrating all the content, troubleshooting the issues and then getting the settings just right in a new system can be overwhelming, especially with tricky legacy archives.

Even though it might appear that the Exchange migration to Office 365 is happening everywhere, transitioning to the cloud is not a black and white choice for every organization. On-premises servers still get the job done; however, Exchange Online offers a constant flow of new features and costs less in some cases. Administrators should also consider a hybrid deployment to get the benefits of both platforms.

Once you have determined the right configuration, you will have to choose how to transfer archived emails and public folders and which tools to use. Beyond relocating mailboxes, administrators have to keep content accessible and security a priority during an Exchange migration to Office 365.

This guide simplifies the decision-making process and steers administrators away from common issues. More advanced tutorials share the reasons to keep certain data on premises and the tricks to set up the cloud service for optimal results.

Definitions related to Exchange Server migration

Understand the terms related to moving Exchange mailboxes.

Microsoft Teams e-discovery enabled for hybrid clouds

For businesses with on-premises Exchange mailboxes, Microsoft will facilitate the electronic discovery of Microsoft Teams chats — a feature that should appeal to large enterprises in the process of migrating to the cloud.

Upon request, Microsoft will create cloud-based mailboxes for the sole purpose of storing the Teams chat data of users with on-premises Exchange mailboxes. Those users must have their on-premises identities synced to the cloud in Office 365’s Azure Active Directory. 

Organizations that take advantage of the tool will be able to search, preview and export Teams chat data stored in the cloud. That activity could be useful for Microsoft Teams e-discovery cases, compliance reviews or data service requests related to the General Data Protection Regulation.

However, businesses won’t be able to apply Office 365 retention policies to that chat data or place it on hold. In a blog post announcing Microsoft Teams e-discovery for hybrid setups, Microsoft said it would “provide more updates about our plan to address this gap soon.”

Microsoft Teams muddles path to cloud for large enterprises

Microsoft needs to continue to promote hybrid capabilities, such as its new Microsoft Teams e-discovery feature, to help on-premises customers feel comfortable with the transition to the cloud — a process that could take years.

“It’s messy to be in the middle, and I think Microsoft forgets that if you’ve got 100,000 people, you’re going to live in the middle for a long time,” said Kevin Kieller, a partner at consulting firm EnableUC in Oakville, Ont.

Many large enterprises with on-premises Skype for Business deployments had previously been gearing up to transition to the cloud version of that platform, Kieller said. Then, Microsoft introduced Teams last year, significantly complicating the cloud migration path for those businesses.

Microsoft has been steadily rolling out interoperability features between Skype for Business and Teams over the past several months, such as persistent chats and aggregated presence. But almost all of those features require businesses to have their employees registered through Skype for Business Online, the cloud version of the service.

“As far as I’ve seen, there isn’t really a good and easy way to migrate from Skype for Business on-prem to Teams,” said Zeus Kerravala, founder and principal analyst at ZK Research in Westminster, Mass. “It just seems like [Microsoft] didn’t think about it very well.”

Advanced telephony features for Teams coming soon

Microsoft is on track to add dozens of telephony features to Teams that are critical to large enterprises by the end of June, including call queues and organizational auto attendants. The final advanced calling features are expected to come online by year’s end.

The perception that Microsoft Teams lacks the full capabilities of Skype for Business has slowed adoption of the platform, particularly among large enterprises. But even as those features get added, Microsoft faces another hurdle: perception.

It could take months to get the message across that Teams is fully built-out, Kieller said. “Microsoft has a tough time, as everybody does, in terms of discoverability of the right information for somebody that’s contemplating this migration.”

Still, there is no end date in sight for support of Skype for Business on premises. However, while Microsoft plans to release a new on-premises server in 2019, the vendor is expected to keep some of its latest and most advanced collaboration tools as cloud-only offerings.

“It’s almost, by definition, going to be a hybrid mode,” Kieller said. “It’s just another way that I think Microsoft, even for on-prem customers … [is] effectively pushing them, moving them, cajoling them to move to the cloud.”

Mastering PowerShell commands for Exchange by the book

The key to manage Exchange Server 2016 is to master PowerShell commands for Exchange.

With this latest version of Exchange, IT administrators must learn how to manage Exchange 2016 mailbox and client access and troubleshoot issues with the edge transport server, which routes email online and protects the system from malware and spam. Part of the difficulty of managing Exchange Server is learning how to use PowerShell, as the web-based Exchange admin center cannot handle every issue.

The book Practical PowerShell Exchange Server 2016: Second Edition by Damian Scoles and Dave Stork, teaches administrators with little PowerShell experience how to use the scripting language to ease configuration jobs or handle tasks with automation.

For experienced PowerShell users, this book shares ways to improve existing scripts. Administrators can learn how to use PowerShell commands for Exchange to customize their servers, manage mailboxes and mobile devices, and create reports.

From migrating to Exchange 2016 to taking advantage of its new functions, this book walks administrators through common tasks with PowerShell commands for Exchange.

From migrating to Exchange 2016 to taking advantage of its new functions, this book walks administrators through common tasks with PowerShell commands for Exchange. This excerpt from chapter 14 explains why mailbox migrations work better with PowerShell commands for Exchange:

It’s very unlikely that there is no Exchange admin that has not or will not have to move one or more mailboxes from one Exchange database to another. While some scenarios are quite easy, there are some scenarios that require some more planning, reporting and so on.

With the introduction of Exchange 2010, Microsoft also improved the one element that would grow into an almost impossible task: Mailbox moves. The revolutionary change in Exchange 2010 made it possible to move mailbox data while the user still could access and modify his/her data: Online Mailbox Move. New incoming mail is queued in mail queues until the mailbox is available again (i.e. when it’s successfully moved or has failed).

Practical PowerShell Exchange Server 2016

With the trend of growing average mailbox sizes, this was a necessary step. Otherwise it could mean that a migration would take too long to perform in a single big bang, meaning that you have to migrate mailboxes in stages and maintain a coexistence environment until the last mailbox has been moved. It was also a major step towards making Office 365 more accessible to migrate to and more flexible for Microsoft on managing servers and databases. Just consider moving mailboxes like in Exchange 2003, hoping that every mailbox has moved before your maintenance window closes… .

Luckily this has changed, and as Exchange 2016 can only coexist with Exchange 2010 and 2013, earlier versions of Exchange won’t be an issue. However, the option is still there with the -ForceOffline switch in the New-MoveRequest cmdlet. You shouldn’t have to use it under normal conditions, however from time to time a mailbox is fickle and can only move via an Offline move.

Now, most of the move mailbox options are available from within the Exchange Admin Center in one way or another. But in our experience, EAC is probably fine for simple migrations or the incidental move of one mailbox. If you migrate your server environment from one major build to another, it’s almost impossible to ignore PowerShell. Those migrations are far more complex and full of caveats, that it mostly always requires the use of custom PowerShell cmdlets and scripts

What are some considerations for a public folders migration?

— but there’s another level of complexity when cloud enters the mix.

A session at last week’s Virtualization Technology Users Group event in Foxborough, Mass. detailed the nuances of Office 365 subscription offerings and the migration challenges administrators face. Microsoft offers a la carte choices for companies that wish to sign up for a single cloud service, such as Exchange Online, and move the messaging platform into the cloud, said Michael Shaw, a solution architect for Office 365 at Whalley Computer Associates in Southwick, Mass., in his presentation.

Microsoft offers newer collaboration services in Office 365, but some IT departments cling to one holdover that the company cannot extinguish — public folders. This popular feature, introduced in 1996 with Exchange 4.0, gives users a shared location to store documents, contacts and calendars.

For companies on Exchange 2013/2016, Microsoft did not offer a way to move “modern” public folders — called “public folder mailboxes” after an architecture change in Exchange 2013 — to Office 365 until March 2017. Prior to that, many organizations either developed their own public folders migration process, used a third-party tool or brought in experts to help with the transition.

Organizations that want to use existing public folders after a switch from on-premises Exchange to Office 365 should be aware of the proper sequence to avoid issues with a public folders migration, Shaw said.

Most importantly, public folders should migrate over last. That’s because mailboxes in Office 365 can access a public folder that is on premises, but a mailbox that is on premises cannot access public folders in the cloud, Shaw said.

“New can always access old, but old can’t access new,” he said.

IT admins should keep in mind, however, that Microsoft dissuades customers from using public folders for document use due to potential issues when multiple people try to work on the same file. Instead, the company steers Office 365 shops to SharePoint Online for document collaboration, and the Groups service for shared calendars and mobile device access.

In another attempt to prevent public folders migration to Office 365, Microsoft caps public folder mailboxes in Exchange Online at 1,000. They also come with a limit of 50 GB per mailbox in the lower subscription levels and a 100 GB quota in the higher E3 and E5 tiers. Public folder storage cannot exceed 50 TB.

Still, support for public folders has no foreseeable end despite Microsoft’s efforts to eradicate the feature. Microsoft did not include public folders in Exchange Server 2007, but reintroduced it in a service pack after significant outcry from customers, Shaw said. Similarly, there was no support for public folders when Microsoft introduced Office 365 in 2011, but it later buckled to customer demand.
