SMPT din't work on Thunderbird mobile

more options

I installed MThunderbird on my Android phone today, using a QR Code to import settings. Receiving messages works perfectly, while sending messages is a mission impossible. I keep getting the message when sending: "Authentificanion failed". I have the same settings on my computer, and Thunderbird works normally, both sending and receiving messages. I don't know where the problem could be, so please help!

I'm also attaching a screenshot of the outgoing server from the desktop computer, which is also set up on the mobile application.

Hello there Bearded.

You try to use that phone and it didn't work out well ,okay, You do use Imap?can you switch to Imap use? If you sure that all settings were okay to use both of these device’s ,okay.

I do think that the telephone is doing well. But the answer on this is leading to a not good configured mobile phone. As the answer is lied near to not good configured account credentials and server settings. These subjects are not related to wrong named receiving maps for that mobile what could give other error messages.

Greetings Googlethunderbird.
