Because the end is listless, this edition of Short Takes looks at a temporary Outlook problem that broke the Internet, Google’s Microsoft envy, a well-intentioned but ill-conceived plan to fix Edge and Chrome memory usage, Microsoft layoffs, and so much more.

Microsoft will remove the Search-Mailbox cmdlet from Exchange Online on July 1, but that doesn’t mean you can’t purge bad messages from user mailboxes. Office 365 content searches and content search actions can hard- or soft-delete messages. Some limitations exist, but not enough to be worried. And we include a PowerShell script to show how to get the job done.

The revelations that Exchange Server has had a vulnerability in the Exchange Control Panel since Exchange 2010 shocked some. Microsoft has patched CVE-2020-0688, but the problem gives on-premises administrators something to think about as they look to the long-term future of their email service. Staying on-premises is an option, but going to the cloud might be more secure.

Outlook users are more than aware of the problems involved in message recall, a feature that’s only available in Outlook desktop and has a nasty habit of not working. The reasons why the feature fails are well known, but soon might be addressed by a new Exchange Online implementation that promises to work for all clients and across Office 365. Time will tell if careers and love can be rescued by the new message recall.

At Microsoft Ignite 2019, the Exchange product group announced the public preview of a set of REST-based PowerShell cmdlets to replace some of the most popular (and in performance terms, most painful) traditional cmdlets. The new cmdlets are more reliable and robust and run 2-4 times faster than the older Remote PowerShell-based cmdlets (your mileage will vary). All good stuff.

A recent Microsoft post contained the news that Exchange Online uses Windows Server Core. That might be news to some, but not to anyone who’s been following the advice of the Exchange product group. Exchange Online doesn’t use virtual servers, follows a preferred architecture, wants to reduce the potential attack surface, and extract as much CPU as possible out of its servers. All good reasons why Windows Server Core helps.

In a surprising but welcome announcement, Microsoft moved the end of extended support for Exchange 2010 to October 2020. This version of Exchange was the most technology-rich and significant in the product’s history, which might be the reason why so many organizations still depend on Exchange 2010 for email. Better options exist, and Exchange Online is the natural place to go… if your network and applications allow the move.

Microsoft has updated the vererable Get-MailboxStatistics cmdlet in Exchange Online PowerShell to return a bunch of new mailbox activity properties. The properties cover different activities like email and calendar, but the problem with the LastLogon property remains and you still need to do some extra work to get accurate last login information for a user.

OWA is the only Outlook client that supports “Likes.” This begs the question how OWA supports likes and where the information about likes is stored. Some probing using easily accessible tools reveals the answer. You might think that the answer only interests Office 365 Trivial Pursuit nerds, but it’s actually of real interest to eDiscovery investigators.
