Unless you have been living under a rock for the last week, you could not have missed that the Microsoft 365 world has been abuzz with worry after Exchange Server 2010-2019 succumbed to zero-day exploits, believed to being used by a group known as HAFNIUM. These exploits are allowing an attacker to compromise Exchange and…
Microsoft has released several new patches for Exchange Server after they discovered an active 0-day vulnerability.
Microsoft has announced that users who receive a high number of messages, they will soon be cracking down on the rate at which you can receive email.
In a surprise development, Microsoft has released the source code for the Extensible Storage Engine (ESE) on GitHub. Fans of the non-SQL database engine, which has powered every version of Exchange since the initial 4.0 release twenty-five years ago, now have the chance to peruse the ESE code.

At the time, my assessment was “I don’t expect Microsoft to ship on-premises versions of Exchange or SharePoint in the way they’ve done in the past because…
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.
