I have a Huawei Mate 20, use there already pre-installed App- Now I have more often the error message 'Connection problem 550: Request failed, Mailbox unavailable'. I have rewritten the email several times, the receiver is also quite sure and yet it does not work. Also tried to send a short mail to myself and friends-was not synonymous. Does anyone have any ideas why this could be so? Google did not make me very smart.

Delete the memory of the app, but then you must reconnect.

Uninstalling will not be enough.

I can't uninstall it, is fixed on the Handy.das with the memory I try, if I find that.

Back up data, set mobile phone to factory settings.

OK then maybe server problem, forget about the factory setting, brings nothing.
