Unable to configure IMAP mailbox in mac machine


The imap mailbox (yunohost user) is configured and was working well in windows and android in outlook application.
I used the following details:
Incoming server: mail.testdomain.com
username: testuser1@testdomain.com
password: testpassword
outgoing server: mail.testdomain.com:587
username: testuser1@testdomain.com
password: testpassword

In windows, i selected SSL for incoming and TLS for outgoing in outlook app.

Everything works fine, BUT iam not able to configure the same in mac machine.

In mac machine, the incoming was fine but unable to send emails out. iam getting an error as:
" Authentication failed because Outlook doesn’t support any of the available authentication methods."
error code: 17895

Does anyone has a successful yunohost mailbox configured in Outlook application in mac please?

any help would be greatly appreciated.

Thanks and Regards,

Hmm, is your software / OS up to date or are you using some old version ? (Just a random guess)

it is up to date. I even checked in 3 different mac machines and everywhere iam encountering the same error.

anyone experienced this issue in mac? kindly help…
