Since January 31, 2020, I have reported almost daily about problems or failures of Microsoft's Azure Cloud services. The last issues was the team failure due to an expired certificate.

New failure in Exchange Online

Blog reader Andreas P. already informed me yesterday evening by mail about new status information about Exchange Online (thanks for that). I haven't found anything on Microsoft 365 Status yet.

Here are the status messages of the administrator dashboard from February 4, 2020.

Title: Can't access archive mailbox

User Impact: Users' archive mailboxes may unexpectedly appear as empty.

More info: This is a continuation of EX199646.

Users' standard mailboxes are unaffected.

This issue only affects users who had an archive mailbox and had renewed their Exchange Online license or had their mailbox disabled and re-enabled between December 4, 2019 and January 11, 2020. Please contact our support team to expedite the reconnection of the archive mailbox.

Current status: We've deployed a restoration script in order to reconnect the archive mailboxes to a subset number of affected users. We're reviewing diagnostic data to identify the remaining users who may still be impacted and who have not received the deployment yet.

Scope of impact: Any user who has an archive mailbox and has recently renewed their Exchange Online license or have had their mailbox disabled and re-enabled may be impacted.

Start time: Tuesday, December 17, 2019, at 9:20 AM UTC

Root cause: A recent update to streamline the process of enabling and disabling mailboxes caused issues with archive mailboxes.

There are problems with mail archives and e-mail accounts in Exchange Online – possibly due to a December 2019 change. Downdetector shows a smaller number of problems over the past 24 hours.
