Reply settings for Office 365 Groups
In fact, you can do that Reply-To rewriting - but not in the group settings alone, you do have to use Exchange mail flow rule for that:
- Conditions: the recipient is [group e-mail]
- Action: Set header value: set header Reply-To value to [group e-mail]
- Rule mode: Enforce
Lukasz032 This doesn't appear to work, I think. Exchange will kick the following message back to you:
You can't set header 'Reply-To' with value '<group e-mail address>'
I think an Edge Transport server is required to do that task. I am playing around with getting M365 groups to do this exact thing and haven't gotten it to work so far.
aseabrookthanks for the update. Here's my use case: I have a O365 group that I want to use for email communication with a group of about 340 users (a professional association) who are all outside of my organization. The list is a place to ask questions and share announcements.
I've been able to replicate most functions we've traditionally used on Listserv using Azure AD and Power Automate. The one thing where I'm stuck is lots of people in our network have auto reply messages to let their usual clients know how to get help for time sensitive matters. When you send a message using O365, you get a whole bunch of auto replies and it's a bit overwhelming. Listserv would have caught those. O365 will prevent any auto replies from going back to the list, but not to the original sender. I was hoping to change the outbound message so that the group address was the sender, then have O365 filter out the auto replies.
I've searched pretty thoroughly, and it seems like this is not possible using Exchange Online (we don't have on-premises services).
I have some ideas for how I might be able to use Power Automate to achieve the same result. Essentially users would send to an email alias, then Power Automate would redistribute the message to the members of the 0365 list. Wish me luck!
BarryPT hi! Thanks for reminding me of this.
I was unable to find a way to do this with exchange on its own.
What I intended to try next, and have not yet had a time to fully explore, is leveraging one of the other platforms in O365 to mimic the Google groups functionally- creating a community either in Teams or Yammer.
I'm pretty heavily into Teams and SharePoint administration and have only scratched the surface of Yammer, but I still feel like the functionality is there, it just needs to be strung together with a Flow or some other type of automation that allows people to email an entire community at once, and then have others reply to that email by default to the same address.
Thank you for reminding me of it, I need to get back on this because I still have an email list that could use the benefit if I figure out how to make it work.
