Hello,

I'm trying to move my emails from Outlook (Office 365) to Gmail. I can drag and drop in the Thunderbird UI; it's working well, except when an email has an attachment. It takes about 45 seconds, and then a timeout appears from Gmail. Is there a solution to increase this timeout?

Please note gmail have limits on number/size of emails that get imported via imap. Maybe your issue is due to the limit being reached ? Upload with IMAP is 500 MB per day. https://support.google.com/a/answer/1071518?hl=en

Do you have any Anti-Virus etc scanning outgoing emails ? If yes, then the intervening scanning process may be slowing things down. Stop scanning outgoing mail.

You could try increasing the timeout.

  • Settings > General
  • Scroll to bottom and click on 'Config Editor'
  • It opens in new tab - Advanced Preferences
  • In top search type: tcpt
  • look for this line: mailnews.tcptimeout
  • click on the pencil icon to edit
  • Increase the number - (mine is 100 by default) try 500
  • click on the tick icon to save
