Hi List Maybe somebody could enlighten me, what is going on....
We very often face the issue of Office365 business customers sending an email to us and asking for reply, but when we reply we get: === schnip === Your message to [RECIPIENT] couldn't be delivered. The group [USERPART OF EMAIL] only accepts messages from people in its organization or on its allowed senders list, and your email address isn't on the list. === snap === I used to think, this is a miss configuration on the o356 customer side. But now I start to wonder, if this is some kind of anti-spam measure which causes the recipient to receive emails ONLY from an email address they previously sent an email to. I have observed that those cases almost always happen when an email for example is sent to our info@ email address, but then replied from a personal email address. So the address replying is not the one the o365 sent the email to. Has anyone more insight in this?
