Just check if there is some mails in the outbox folder thats blocking.

it just shows downloading ## of ##### in inbox

try this

• go offline,
• open troubleshooting information (under help)
• copy to clipboard (use button)
• open show folder (explorer opens)
• close Tbird
• find your servername (under mail or ImapMail)
• Open that directory
• delete INBOX.MSF (just the .msf-file) It will be recreated.
• start Tbird (now in offline mode)
• When tbird is ready rebuilding .msf .... Go online

If it behave as it should, great, otherwise paste what you copied earlier here (or get it again)

Did it work? go offline and compact your boxes go online to see whats happend. Use webmail to check whats in your boxes.

It didnt work.. im not sure what you mean by 'boxes' and 'webmail'

My confusion, Tbird stores the email in whats called a mbox = your folders. Also folders are sometimes named "outbox" or "inbox" etc. Webmail: You can login to your gmail-account using Firefox or IE or Crome or ?? and check whats in your INBOX

My current inbox in gmail and in Tbird is up to date.. i am not missing any emails in inbox and outbox or any other folders yet it is still downloading... (see image of previous post)

Read this about McAfee.

https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee

Doesn't help.. see screen shot :(

Have you checked the INBOX at the server (GMAIL.COM) using webmail???

Apparently you are keeping messages on the server.

Now im talking about server-side:
Are there many  in INBOX? Is trash empty?

what should happen when you delete and empty trash? Are they still kept in "all files"? Make a new folder on gmail and move all your inbox files there. start Tbird. If it doesn't download compact your inbox. If it still does go offline repair your inbox try again go online. If all well, subscribe to your new folder.

IF YOU'R NOT keeping them on seerver (account-settings / syncro.... / marked "keep messages for ......." then move all from your inbox on Tbird to a local folder (while offline)

Not sure what you mean.. but still freezing up my computer and not working

Keep Tbird not running. Login with webmail (using Firefox or IE) to gmail.com (thats the server) This is when you are logged in: Do you have many emails in that inbox? Empty the junk- and trash- folders? Make a new folder (still on server) Move (not copy) all emails in your inbox to that folder. Zipp thru the content and delete as much as you can. Empty trash log out from Gmail.

Start Tbird Is it still trying to download? If good then right click on your account and subscribe to that folder you made earlier.

OH and do not subscribe to All Mail (maybe that was the trouble from the beginning)
