Microsoft Teams email server – Microsoft Community Hub



I’m having an issue that I’ll try to explain in few steps:

1. Our company has O365 Business Standard licenses.

2. We are using our own locally hosted mail server.

3. By default, when creating Teams meeting, mails would be sent from “”. Our boss didn’t like that, as people are unable to reply to it and he wants it to me be sent from our domain.
4. I’ve tried fixing issue by adding our domain to tenant, but now there is no mail sent at all. In logs it is possible to see that he tried to send mail by Microsoft Exchange but it is not possible since no settings regarding mail dns and other stuff were set (everything is still pointing to our local mail server) and I can’t change that since employees that don’t use O365 at all would lose mails.

My question is, does anyone have any idea how can we force Teams to send email invites with our mail server and/or domain (not without fully transferring email to Microsoft Exchange ?


Thanks a lot in advance !
