In a service alert spotted by BleepingComputer, Microsoft revealed that the glitch started on February 5 and has been preventing some Exchange Online users from sending and receiving emails. "Some users' legitimate email messages are being marked as phish and quarantined in Exchange Online," Microsoft said in the service alert. "We've determined that the URLs associated with these email messages are incorrectly marked as phish and quarantined in Exchange Online due to ever-evolving criteria aimed at identifying suspicious email messages, as spam and phishing techniques have become more sophisticated in avoiding detection."

"Customers have shared that this limitation creates significant operational challenges. Your feedback is important, and we are committed to solutions that balance security and usability without causing unnecessary disruption," Microsoft officials wrote on the Exchange Team blog.

The plan, which Microsoft refers to as "reimagining archiving," involves automatically moving the oldest items from a user's primary mailbox to an archive location when the mailbox approaches 90 percent of its quota. Administrators will be interested to learn that the function will also temporarily override the current archiving policy and cannot be turned off if archiving is already enabled.

Microsoft Exchange Online is experiencing an outage that mainly affects European users. Users have been experiencing delays in sending and receiving emails since around 12:30 p.m. Central European Summer Time. Several users have reported experiencing problems, although the exact extent of the issue is still unclear. Microsoft acknowledges the problems on a support page in the closed admin center. The company states that "some users located in Europe" may experience problems sending or receiving emails via Exchange Online.
