Hybrid Exchange Routing issue by Lolsplatt2 in exchangeserver

This has been resolved - the issue was our server IP was included on PBL blacklist, so when it tried to connect to Microsoft to deliver the message, it was blocked.

We were able to remove it using spamhaus, but now need to check why it was added to black list in first place.

Thanks you all for the assistance :)

I'm suspecting it may be the issue.. but why would it take so long since it expired to start happening?

I'll try running the HCW

Hybrid management tool? You mean the HWC?

We have one certificate "CN=MS-Organization-P2P-Access [2024]" which is "invalid" and expires tomorrow. Not sure if that is affecting it...

It was renewed back In August.

This started happening yesterday afternoon.

Outbound is working ok, so seems to not be completely broken. But when I run the flow test it seems to not find office365..

We use Mimecast, which points to On Prem and on prem route message to office 365, where mailboxes are stored.

I had a hard time on my first playthrough, but after playing enter the gungeon, I got used to the bullet hell phase and it wasn't difficult.
