Hello,
Seriously this bug has been going on since 2015.
I am not a Microsoft MVP anymore. I was wondering if current MVP or Microsoft employees could report this to the highest level.
After successfully connecting a Gmail account it keeps disconnecting after some time (1 or 2 days) and we cannot use it to send messages from Outlook.com. This may concern other third-party accounts. Note that Microsoft directly added Gmail OAuth API to connect.
Error: "Couldn't send the following message"
Affected: All browsers / All OS - It's a server bug
Thank you
