Hi!

I have several checks where e.g. a Synology NAS sends a Mail for HyperBackup or Snapshot Replication State to a mail address from us. In Outlook web, we then have forwarding rules configured, that forward some of these mails to CheckCentral. I have now an Issue with only one check, which worked previously.
We receive the mail from NAS, the rule gets processed, but the mail is not processed by the Check or received by CheckCentral at all. I don't see the mail in the Activities.
What I tried:
- Checked Message Trace in M365: The mail leaves the tenant. If I add my private mail as a recipient in the same Rule, i receive the forwarded message.
- Created a whole new check with a new checkcentral alias several times - still not working.
- Forwarded the mail manually to the exact same CheckCentral mail address as in the forwarding rule - then it works and the message is assigned to the correct check.
- Created several new forwarding rules - same effect.
- Created a ticket, but either did not receive a response or it got lost somewhere too.

Do you have an Idea what could be the case?

Thank you and best regards
Christian
