554 5.6.0 Permanent error while processing message
Hello, We have one mailbox with the issue: when the user wants to send an email with an attachement bigger than 1 mb, the servers returns immediatly the error. This mailbox was OK until yesterday......
Having the exact same issue. One random user mailbox.
3.5 hours on with MS support still no resolution.
I am looking at the outbound filters and rules for my org while I wait for MS to call me back again. Let us know if you get anywhere with this...
thanks,
I've deleted the recoverable items on the mailbox, and after a couple of hours, all was working fine again
