« on: December 23, 2019, 03:55:45 pm »
Hi, since a few days ago Aquamail suddenly can't access my account anymore. I think it was just about after an android update.
I found a thread with a similar problem here: , but it's an old thread and it couldn't help me.

The error on the main menu says "Error synchronizing mail, Authentication error: NO Login failed: Authentication failure". When I try to manually reset the settings, Aquamail can't sync up the outgoing server, and gives the error: "Outgoing mail server (SMTP): Error connecting failed to connect to (port 587)"

My settings are SMTP-server:, security type: STARTTLS (strict check), server port: 587. Two-factor auth is not set up on my outlook account. I've tried on multiple Wi-fi networks and 4g connection.

Any assistance would be appreciated, thanks.
