Hi all,
One of our Exchange 2013 CU9 user systematically receives an error 550 5.1.1 when an incoming email arrives whereas OOF activated.
This error is about an email deliver failure to a recipient that has been deleted.
When I look for a possible email rule, I find nothing. In addition, this issue occurs only when OOF is activated.
Any idea about that ?
Thank you.
