Failed to send
This is not a problem since March, the 75M Teams do not have an issue. At the time of the original message in this thread there was an outage at Microsoft, it lasted a few hours and is long gone now.
In general the failed to send error would imply your network is blocking access to some of the Teams messaging URLs, perhaps through a proxy or other network device. Try it in a browser and bring up the F11 debug tools and you'll quickly see which addresses are not responding.
We had this issue in one of our Teams chats. The issue ended being one of the users in the chat was no longer with the company, that account had been either disabled/not enabled/allowed to login, and the mailbox had been converted to shared inbox. 'Sign-in Blocked'
Immediately after removing the problem user from the chat, attachments to the teams chat started working and no longer 'failed to send'
