No mails incoming Exchange Online since this morning

Hello,

currently since a few hours I don't get an incoming mails - outgoing is working perfectly fine.

Also no NDR is created, can it be that this is still related to the issue a few days ago?

Wondering, cause colleagues from other companies don't have thi issue.
Sitting in Germany.

Edit for so far done troubleshooting:

Yes you are right, excuse:

- MX Records are point to Exchange Online Protection
- Message Trace shows NO incoming mails, only outgoing (started at around 9am this morning)
- No Mailbox rules or something
- It is for all user in my Tenant (3 currently)
- No Connectors or soemthing configure, it's cloud only

Greetings
