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 are also having troubles ... we cannot send messages inside a channel ... whereas we can send everywhere else ... is there any solution yet ? any workaround ?
I'm having a very similar issue. I can post to all teams bar one, and I keep getting the same error message as above.
