Hi, my Gmail account on Tbird is failing to copy sent emails to the sent box. The email hangs with "connecting to Imap Gmail" and then "your email was sent but a copy could not be placed in your sent box". I have re-downloaded Tbird, deleted and re-connected to Gmail but the problem persists. I have tried the fixes mentioned on this forum in 2024 (e.g. changing the destination folder as suggested, changing threads to "all") but nothing seems to work. Help!!
