Cant share/attach files in MS Teams chat
It would be good if there was a setting to control messaging policies for chats with external parties, but there are no options in the Teams Admin center for this (at least as far as I can see). I use 3rd party document management software so the ability to share actual files and not links is critical otherwise I may as well revert to email messages.
Sorry I can't help but perhaps someone else has a workaround or idea for this.
NickPuzzle The other options are to use Teams and Channels. You would need to bring the external parties in as Guests (which have higher permissions than External users) or set up shared channels with their tenant.
HelloBenTeoh so actually generating teams channels for external parties vs group chats only. Not a bad idea thanks. Would that mean the external party has to switch Teams tenants? I don't think the external chat messages require tenant switching. Thanks for the advice, much appreciated.
NickPuzzle if they're added as a Guest, they'll need to switch tenants (but they won't need to sign out of Teams).
If you go down the path of Shared Channels, it's a bit more effort as your Teams Admins will need to coordinate and set up B2B direct connct (B2B direct connect Microsoft Entra overview | Microsoft Learn) but it means they won't need to do any switching and your channels will appear in their regular teams/channels area.
Here's some more info on Shared Channels: Shared channels in Microsoft Teams - Microsoft Teams | Microsoft Learn
