Mail always re-fetching for one mailbox

[mmagier]

Hi All. New here.
Running 10.7.4 on iMac and PowerMac. Recent onset of same issue on both machines. Running Mac Mail. 2 IMAP accounts, one is iCloud. Numerous mailboxes on iCloud. In only one of these mailboxes, every time I view ANY message, there is a delay, the view pane shows "Loading" and the activity window shows "Getting message . . ." It will eventually load correctly. None of my other mailboxes show this behavior. They're all instantaneous view, as you would expect for locally stored messages. My preferences include local storage of all messages and attachments. The mailbox in question has 312 messages, the mbox file is about 30 MB. Also, every time I start Mail, it spends a VERY long time "Updating attachment names for messages."
I've tried rebuilding the mailbox. I've deleted the account and re-adding it. I've tried archiving half the messages. I've tried renaming the mailbox. I've tried deleting the Mail prefs. I've tried the "sqlite3 Envelope" thing in Terminal.
As I said, identical behavior on 2 different machines.

This is troublesome, as it's my most-often-used mailbox, contains rather important "legal" messages which I need to refer back to often.

As I said, it just started doing this about 3 days ago.

Any help out there?

Thanks.

No idea why Mail.app is doing multiple refreshes.
But if you refer to these documents often, why not put them into a folder in Finder?

Keeping them in IMAP mail to be able to access easily from various locations.

You could use iCloud (or Dropbox) for this.

Sir, can you tell me which one is best iCloud or Dropbox. ?
