We are currently running office 365 for one of our clients and they are saying that they are getting bounce back messages when e-mailing them stating Delivery is delayed to these recipients or groups:.
I have had a look into this and called the company in question who say it's on our side not theirs. I know they are using google mail as their provider for e-mails. Are there any known conflicts between the 2 which could be causing such a delay?
Thanks in advance.
