Channel stopped linking to email attachments
As of March 12, 2021, Teams has stopped doing something we relied on. When someone needs to order supplies, they fill out a form. That form then sends an email with an attached PDF to a Teams Chann...
I had the same issue. This is happening because an untrusted user is sending to the Teams channel. If you go to the Sharepoint site and add the user to it. The proper envelope icon will show up again. We resolved ours by routing the messages to a trusted mailbox, then had that mailbox forward the messages to the Teams channel in question.
In our case I couldn't add a user, since the emails were sent by a system account of our phone system (voicemails). It also works again if you add trusted domains in the email settings of the channel.
It stopped working again - since about 13:00 CET Teams stopped adding attachments to the channel. The channel is configured to accept mails from 3 domains - no change has been made.
