Thunderbird freezes for long when sending or moving a message with an attachment

Hi,

I would much appreciate your help dealing with attachments in Thunderbird.

1) Whenever I sent (or save as draft) a mail message containing an attachment, TB freezes for 20-30 secs (for a pdf of say 300kb; longer when bigger).

2) The same long freeze happens when I move a message with an attachment from my (IMAP) sent folder to my (local) archive. If I move multiple mails with attachments, this freeze can easily take up to a minute or more.

TB is set up to cache all messages offline for all accounts & folders.

Could you please advice me on how to solve this freezing?

Mant thanks, Galua

How large are the folders on disk? Right click, select properties to see the size.

Create two new folders. Copy a mail into one and wait a few minutes, now move it from the first to the second folder. Do you see the same delay?

Hello Matt,

Thnx for the quick reply.

I've done the test with 2 newly created local folders. TB freezes for about 40 secs when moving the mail from one to the other (the test mail containes 2 attached pdf's of together 169kb)

Any thoughts?

(the folder size doesn't seem to be an issue. The same happens with small and bigger local folders.)

On Windows my first suggestion would be to exclude your Thunderbird profile folder from your anti virus scanner. But do you even have one?
