Since today i have this authentication failed message. It was always configured to "Auto", i tried the rest and did not worked, only "Plain text".

I also tried giving access to Opera with an App Password (when two step security is enabled), but it did not matter because the problem did not got away.

I noticed that the messages not showing in the regular view (ex. Outlook tab or section) they do appear in

All Messages-->Received

How do i make them show up in Outlook section?

Thanks it worked, but i had to re-enter the passwords.

Thanks for your reply. IMAP is enabled in Outlook.com and in Opera. The server is imap-mail.outlook.com.

I noticed today that Opera Mail was not downloading all of incoming email. But when i go to Outlook.com directly with a browser the email messages are there.

I want to backup the email accounts because i will need to refresh Windows 10 and i don't want to re-enter every email account again because i have 5.

Hello,

I am new with Opera Mail client. I already have configured 4 email accounts and i am receiving messages without problem, but i would like to do a backup or export the accounts if possible so in a case of corruption i could avoid setting the accounts again (setting passwords, IMAP settings, etc).
