[German]Short message for Exchange Online administrators. If no mails were delivered or messages ended up in quarantine as of today, March 21, 2025, it is not due to the tenant. Microsoft has posted a message in the Microsoft 365 Admin Center under EX1038119 that a bug is being investigated that causes messages to end up in quarantine by mistake.

I don't have access to the Microsoft 365 Admin Center – but the colleagues at Bleeping Computer picked up on the EX1038119 bug a few minutes ago in the following post and the article Microsoft: Exchange Online bug mistakenly quarantines user emails.
According to the entry EX1038119, Microsoft is investigating a bug in Exchange Online that causes anti-spam systems to incorrectly quarantine some users' emails. The problems, which have been classified as a critical service issue, began at 10:11 UTC (12:11 CET).
It is unclear which regions are affected. Microsoft only writes "Certain URLs are being miscategorized and quarantined by our anti-spam systems, which is having an impact". The Exchange Online emails of some users then end up unexpectedly in quarantine.
Microsoft's efforts to add the affected URLs to the appropriate permission list have so far been unsuccessful. The technicians are currently trying to manually correct the affected e-mail locations to eliminate the effects and are looking for further incorrect URLs. Has anyone been affected by this bug?
