Teams email notifications of missed chats coming from wrong email address?
For the past several days, when some users have missed a chat message in teams and they are setup to receive an email notification, the sending email address of the notification is incorrect. It has always been that these notification emails appear to be sent from the person who sent the original chat message, but now, they are being sent from our global administrator account email. Obviously creating lots of confusion and has broken these users' ability to reply via email. Has something changed, or is this a bug?Teams Messaging Gets Autocorrect
The addition of Autocorrect for messaging is a small but important change for Teams messaging brings Teams up to speed with the other Office applications. It’s taken Teams a little longer than it perhaps should have to support Autocorrect and the implementation is not as functional as it is in Outlook, but that’s not a reason to overlook the update. https://office365itpros.com/2025/12/10/teams-autocorrect-messaging/
Require approval from IT to join a Team and/or Shared Channels
My company has two sides to its business. Both sides are under the same Microsoft 365 tenant. They can be called Group A and Group B. Group A should not be able to add those from Group B into teams and channels on their own. Likewise, Group B should not be able to add those from Group A. If either side wants to add the other to a team or channels, they should have to get approval from IT, with IT making the additions to the team or channel. We would rather not have this just done over emails. This has to be done while still allowing members of Group A and members of Group B the ability to have 1 on 1 and group chats. Does anyone have any suggestion how to do this?
