On November 22, 2021, at ~7:44 am UTC, Microsoft communicated via tweet (@MSFT365status) that they were investigating an issue in which users were unable to load images in Microsoft Teams chats or channels.

For IT professionals and system admins with Microsoft admin center access, the initial issue # was TM299667.

Twitter followers responded shortly and gave some indication that the matter involved more than just image loading with Teams chat.  Some Twitter followers also responded and stated that the image loading issue had been an issue for several days, notwithstanding the message Microsoft tweeted this morning (November 22)  indicating that the issue was a "new" issue.

Approximately 30 minutes after their first message, Microsoft followed up with a second message giving no further indication as to what the precise issues and impacts were, and no indication as to what the cause of the issue was.  Microsoft only stated that a fix had been applied to remediate impact.  Microsoft also provided a second issue #, LY299673, for IT professionals to reference in the admin center.
