I'm having the same problem, but clicking the stop sign doesn't resolve the problem. This is under 10.7.1. I tried deleting my email account through System Preferences and rebuilding all my mailboxes from scratch. No luck. Activity Monitor shows Mail downloading a data from the Exchange server for a few seconds after startup, but then it grinds to a halt.

This still happens constantly under 10.7.2.

Agreed that this still happens all the time under 10.7.2.
Also, I have my doubts about the 'corrupted message in the Exchange mailstore' theory. This is because I have Mail set up to vacuum everything out of the Exchange mailstore and refile it on local disk, so my Exchange mailstore typically has only new messages in it, and that only transiently. Unless the occurrence of new corrupted messages is crazy frequent (multiple times per day) this theory doesn't explain what I observe.
FWIW clicking the stop sign does clear the condition for me always or almost always, although frequently I have to click it several times in a row.

I too have this problem. 10.7.2.

I am having this problem with Mail 5.1 under Lion 10.7.2. Invariably, I can click the red stop sign and Mail recovers at that point. Oftentimes, it will immediately hang again with "Requesting Latest Information". I can click the red stop sign again, and it recovers again. Sometimes this cycle repeats 4 or 5 times in a row.
It's a pain because sometimes I don't immediately recognize that Mail has gone into this "deaf loop" requesting the latest information. I sometimes wonder how long it's been sitting there spinning.

I had the same problem, and was eventually able to "fix" it, in an unsatisfying way.
I noticed that I always got the "requesting updated information" message along with "moving messages" or "copying messages". Clicking the stop sign on the "requesting updated information" message sometimes got it un-stuck, but sometimes then left one or more mailboxes in an inconsistent state, which required me to do "Rebuild mailbox" frequently.
The solution? Disabling all of my auto-filing mail rules. It seems that the problem occurred when these rules were being triggered to move messages from my inbox to a local mail folder. I turned off the rules, and haven't had the problem since then. I can move messages by hand which does not cause the hanging problem.
This is unfortunate, since I really like being able to auto-file messages by project. I didn't have this problem with Snow Leopard.

I had this problem with Mac Mail.app (in Lion) and Microsoft Office 365 exchange. We eventually turned off the "Exchange" email account in Mail.app, and set up an IMAP account instead. We left the Exchange account enabled in Contacts.app, iCal, etc.. just set up IMAP and SMTP for our Exchange account. So far so good!

Me too. After being on IMAP for about a month, I'm happy with the result.

I've been irritated by the same ongoing problem too: disabling client-side rules helps but not entirely reliably in my experience. The one new observation I have to contribute is that the problem appears to have been *fixed* in Mountain Lion (on my MacBook that used to display the same problem). Unfortunately my desktop Mac Pro is too old to run Mountain Lion :-(
Presuming that Mail.app v6 (the Mountain Lion version) won't run on Lion, what chance of a maintenance update to Mail v5 for those of us left behind?! Presumably Apple have identified the cause of the problem?

I had to delete and re-configure my Exchange account after upgrading to Mountain Lion, but Mail.app has since run without a single hang. Mountain Lion simply smokes Lion in any way you'd want to compare them, with the exception of loosing RSS support in Mail.app.

I see the last two posts have recorded improved results with Exchange in Moutain Lion. My question is, is the improved performance with Rules enabled. Rules appear to be the most common culprit if Mac Mail hanging in an exchange account.

I have five or six rules on my Exchange email and haven't had a single hang.
With Lion, I'd get several hangs a week.

I'm on Mountain Lion (10.8.3) with Mail 6.3, and I also had Mail hanging with "requesting latest information" in the Activity window. Disabling all rules did indeed help, but that is somewhat dissatisfying. I have more than 30 rules to move mails into local mailboxes.iMac, OS X Mountain Lion, 27in, Mid 2010
