Question about Windows Live Mail and IMAP Accounts

Hey guys,

Just got a quick question regarding Windows Live Mail. I know it's probably not supported anymore (the version I installed is from 2011, even!) but my mom uses it for her email, and has been using it since it came out in 2011, and we just now switched over from POP3 to IMAP.

I had her recreate all her storage folders in the IMAP server, so that she can access them from the new Windows 8.1 tablet we got her as well. The messages being stored on my ISP's server and not locally makes that super convenient and easy

Well, the problem is that with POP3, when my mom would click the "Sync" button, it would only do two tasks - check for new mail on the POP3 server, and send anything in the Outbox.

Now with IMAP, it checks *every single folder* for new mail, and since she has about 75 folders, the entire process takes several minutes. We only want it to check "Inbox", as that's the only place new messages would be anyway... the other folders are strictly storage folders that messages get moved to once she's read them.

There was a setting under Account that looks like this:

I tried unchecking "Check for new messages in all folders" but that did nothing. Not even restarting the program changed anything... it still tries to check all 75+ folders and takes a very long time.

Any suggestions or ideas?
