HI, We have recently migrated our email away from one provider to O365. Since then, I now have 3 users that do not get notifications anymore when tagged in tickets, or forwarded .

If a secondary domain address we have is used (which has a email divert set up to the address onthe primary domain), then they get the notifications on the primary domain email.

If I change thier primary email in Freshdesk to be the onmircosoft.com (or our secondary domain account), then they also get the email,

Running a delivery report from the 0365 dashboard seems to show that these emails are not even hitting the o365 email system.

Is there a report in freshdesk I can run that would should any bounced back email send from our freshdesk account, and why they bounced ? 

Thanks in advance
