Office 365 group to receive external email
Hello all,
Lately I have been running into an issue with trying to email to an Office 365 group with an external email address. Even with the group having external email enabled, none of the email ecternally is coming through. Does anyone know how this can be fixed?
Thank you
- Is this an issue happening Today? I'm asking this because EXO is experiencing a lot of problems Today...at least in my EMEA tenants and I think is also affecting Outlook.com e-mail
- Juan Carlos González Martin I'm experiencing the same problems today, including Outlook.com. Possibly an EMEA wide issue.
- Agree John, and problems are still there...I have several customer asking me what's happening with e-mail today...and my Microsoft accounts have not received any e-mail since a while
This has been an issue from the start. We are trying to have this work and unable to do so. I am not sure that other steps have taken place to ensure external emails can send to Office 365 groups.
- I think you need to follow your mail through to figure out what's happening. If you use Mail trace in exchange, find messages heading to that address and see what's happening to them.
Can you do a message trace? Also, there have been some issues with Exchange online for Anti-x piece. Can you look at your spam configurations or quarantine emails? There have been issues going on with message quarantine for last few days with O365 tenant.
Tim Ihrig, please make sure, your Domain DNS settings are set up correctly, especially the MX-Record.
Go to: https://admin.microsoft.com/AdminPortal/Home#/Domains and check, if everything shows up ok.
One common problem in your case is caused, when a migration from Exchange on premises is not yet completed to Exchange Online and the DNS-MX record is still targeting the on premises Exchange, which does not know the MS 365 groups.
In that case, the sender might e.g. receive an e-mail error message containing:
autodiscover.[your e-mail domain] Mail delivery failed : returning message to senderKind Regards,
Achim
