Email Delivery Issues With O365 Accounts
The organization that I support continues to have issues with emails coming from Expensify that the concierge has been unable to resolve. Most of the time they arrive but the morning is typically when they fail to arrive.
Through the concierge we have been provided three different domains that email should be coming from:
However running message traces against the domain I only show emails coming from the expensify emails. I also manually reviewed all messages that show as failed and spam filtered and none show that could have possibly been expensify. Upon logging in it will sometimes say that it has issues delivering and that we need to whitelist the domains and then click the button to deliver emails again. We click the banner message as requested saying we whitelisted the domains and it works fine for a couple days and then we get the banner again.
In case it matters, here are additional factors:
- It is going to a distribution list set to delivery to multiple people handling that account
- We recently migrated from Google Workspace to O365. I also ran a message trace in Google's panel but nothing shows to have been received since we changed the MX records over.
- No other reports of missing email.
