Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Leslie,
Thanks for your updates.
If the group option “ Subscribe New Members” has been enabled, and the group members are still receiving group invitation emails in their own inbox folder. In this case, your group members ( including yourself) can try to sign into the office 365 outlook web app(https://outlook.office365.com/owa/ )and then find out the group settings which is on the up-right corner of the outlook web app, follow the steps below to have a try:
1. Click the office 365 group which you don’t want to receive invitation emails in your inbox folder.
2. Please click the group settings, and then choose “ manage group email” in the settings
3. In the Stop following in inbox settings, please try to "choose receive only replies to you" or “Don’t receive any group messages option”.
4. Save your changes and then check if you still receive the invitation emails in the group.
If you got any updates, welcome to share with me, thanks.
Regards,
Oliver
