Hello,
Iv got a windows 11 fresh install with thb 91.6.1 (64 bits) and avast free 22.1.2504 (version 22.1.6921.709)
It's impossible to send or draft save an email with my gmail account with an expired smtp error detected. When i switch off avast protection it works.
My parameters of connection are correcte (imap smpt ssl/tls oauth2 993 in 465 out)
note : my other accounts(not gmail) works fine
best regards
