Password required, server says unauthorized, not yahoo

The email is set up on Microsoft Exchange.

Until midday, the mailbox was working normally. Then suddenly, this message started to appear. Incoming messages do not show up, nor can I send anything. The mailbox is definitely working because I can log into it through the browser.

I am having the same problem intermittently (3-4 times a day). I have to close the app and restart to fix it. It is starting to get very annoying and I need to find a fix.

Error log follows.

Until midday, the mailbox was working normally. Then suddenly, this message started to appear.

If you have any optionally installed eg: Firewall / Security programs, or Antivirus programs or VPN’s installed other than what comes default with the OS, try completely disabling those to test.

If that makes no difference or you don’t have any optionally installed programs like that, then it might be something related to eM Client V10 Beta which you appear to be using from the error log.

I would suggest to email the error and the log to [email protected] who can then advise if its anything possibly related to the V10 Beta. Also let them know what version of Windows you have.

timc1 · February 16, 2024, 2:28pm

Thanks. All I have installed is Nord VPN and I have disabled it. Same problem. I will send the log to the testing email.
