Hello, I recently switched vom TB 2.x to 3.0x.
I use IMAP, the inbox-file in TB 2 was approx. 1. mb big, the new one is over 50 mb.
How do I undo the change?
Thanks a lot for your help!

Did you try compacting the inbox? (right click the inbox)
I just did, but it has no effect on the size of the "inbox"-file.
My understanding is that TB3 now stores a local copy of IMAP email by default. TB2 has the option though it was off by default. Try poking around in Synchronization & Storage.

"With new IMAP accounts, offline folders are enabled by default. When necessary, existing IMAP folders are configured to be offline. Disable either in the individual folder's properties or in Account Settings | Synchronization & Storage. (Click the Advanced button on the Synchronization & Storage page to access a folder list that allows you to specify a group of folders for offline storage.)"
