Hello,
I have migrated two of our clients from on-premise Exchange servers to Office 365. Since their migration, my own office, which still has an on-premise Exchange server, receives emails from these two clients delayed.
We only have these delays from the Office365 servers coming into our own servers.
Sometimes there is no delay but more often than not, delays can be several hours long.
Any ideas?
