O365 Network email notifications not working

[Eric Mullerbeck]

I've joined several communities and spaces, and have edited my personal preferences for notifications. I've never received a single email notification from the Office 365 Network (including into my spam folder). Is there a plan to get email notifications working? A couple of previous posts on this topic, dated in July, seemed to suggest there was...but no sign of it for me.

They should be working fine now, but if possible check whether they are not blocked before reaching your mailbox (for example, run a Message trace if your mailbox is an O365 one).

Notifications are definitely still not working.

My mailbox is O365. What information do I need to give our IT admins, in order to run a "Message trace"? Presumably at least the email address from which the notifications come; it would be helpful to know at least that (since as mentioned I've never seen a notification from this network).
