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?


A public folders migration from one version of Exchange to another can tax the skills of an experienced administrator…

— 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.

Cryptocurrency exchanges increasingly targeted by cyberattacks

Hacks on cryptocurrency exchanges seem to be on the rise.

Youbit, a cryptocurrency exchange in South Korea, filed for bankruptcy after losing 17% of its assets in the second cyberattack it has suffered in the last year. In April 2017, Youbit lost nearly 4,000 bitcoins in the first attack — worth about $5 million at the time of the theft but now valued at tens of millions of dollars.

Youbit has said that its customers’ cryptocurrency assets will be marked down to 75% of the full value and has stopped all trading in an attempt to minimize any further losses to the company and its customers.

Korea Internet & Security Agency (KISA), the South Korean government agency responsible for internet security, linked the April cyberattack to North Korea, though there’s no word yet on who may be behind the most recent attack. Attacks on other cryptocurrency exchanges Bithumb and Coinis this year have also been blamed on North Korea.

Youbit is one of the smaller cryptocurrency exchanges in South Korea, while Bithumb has about 70% of the bitcoin trading market share in the country.

A different cryptocurrency exchange, EtherDelta, took to Twitter to alert its customers to a cyberattack on its systems.

EtherDelta shut down its site and services when it learned of the cyberattack. In its tweets, the exchange warned that its DNS server was compromised by malicious actors. Since the initial tweets, EtherDelta followed up Thursday morning saying it is “in the last step to bring the service back.”

EtherDelta is ranked as the 85th largest cryptocurrency exchange, according to CoinMarketCap. It is known for offering a selection of alternate cryptocurrencies before they become widely available and is only a cryptocurrency-to-cryptocurrency trading platform; customers cannot convert cryptocurrency holdings to fiat currencies through EtherDelta.

DNS hijacking attacks on cryptocurrency exchanges aren’t unusual either, as the websites of Classic Ether Wallet and Etherparty initial coin offering also both suffered similar attacks this year.

Hackers were also recently able to steal nearly 4,700 bitcoin, worth almost $80 million at the time of the theft, from Slovenian bitcoin exchange NiceHash.

In other news:

  • The facial recognition authentication technology in Windows 10, called Hello, can be bypassed with a simple photograph, according to security researchers. Matthias Deeg and Philipp Buchegger of the penetration testing company SySS GmbH, based in Tubingen, Germany, posted a warning about the issue with the Hello program earlier this week. “Due to an insecure implementation of the biometric face recognition in some Windows 10 versions, it is possible to bypass the Windows Hello face authentication via a simple spoofing attack using a modified printed photo of an authorized person,” the researchers explained. They listed seven different builds of four different versions of Windows 10 Pro that are affected by the vulnerability. The researchers also noted that enabling “enhanced anti-spoofing” on the system makes the spoofing attack less reliable, but it doesn’t actually stop the attack.
  • Facebook introduced a new anti-phishing security feature this week that enables users to check if the emails they receive from the company are legitimate. Facebook notifies its users when there is a suspicious login attempt or authentication activity on their account by sending them an email. Malicious actors often try to spoof those emails and trick Facebook users into clicking on a malicious link or going to a phishing site. Now, when users receive an email, they can log in to their Facebook account, check their security settings, and see any recent emails Facebook has sent them. If an email is listed as sent, they know what’s in their email inbox is legitimate. If no email is listed, users know that what they received is malicious. This new feature is the latest attempt by Facebook to prove that it takes user security seriously. The company came under fire when it was discovered that malicious actors tied to Russia placed thousands of ads on Facebook in an attempt to influence the 2016 U.S. presidential election. Mark Zuckerberg followed up by saying, “We’re serious about preventing abuse on our platforms. We’re investing so much in security that it will impact our profitability. Protecting our community is more important than maximizing our profits.”
  • Five hackers were arrested in Romania this week due to ties with international ransomware attacks. Romanian law enforcement worked with authorities from the Netherlands, the United Kingdom and the U.S., as well as Europol and security company McAfee to bring in the suspects who allegedly spread ransomware through Europe and the U.S. They seized hard drives, laptops, external storage devices, cryptocurrency mining tools and documents from the suspects’ houses in connection with strains of ransomware known as CTB-Locker or Critroini and Cerber. The suspects are not thought to be the authors of the ransomware, but distributors of it. CTB-Locker ransomware is known to be difficult to detect and often spreads through phishing messages. It was one of the first ransomware families that used the Tor network to hide its command-and-control infrastructure.
