Office 365 rejecting inbound mail
Posted on 2015-01-09
Im trialing office 365 at the moment and have a domain attached to said account, the issue is that if i send an email from gmail from a web browser i get the below error, but if i send the same gmail email from within an outlook configured account the office 365 account recieves it no problem, so far all other domains i have tested ok sending and recieving from the 365 email address
any ideas, thanks in advance
