Microsoft Outlook and IMAP issue

Sometimes when the email is too big, outlook will freeze while retrieving the email, causing us unable to use the email client totally for a few minutes.

Outlook 2003 has an archive file limit of 2GB, when it reaches that size, we will need to move to a new archive file. When manually moving the emails (drag and drop, copy and paste, etc), there seem to have no limit on 2GB, I have experience going up to 2.5GB and we still can copy emails over there in the new *.pst file, well, I stopped at 2.5GB just to be safe.

As IMAP is fetching headers only from the mailbox, generally IMAP is faster than POP3 protocol in searching for new emails. And especially if we get a lot of large emails and we want to delete them without downloading it, IMAP is the way to go. Especially on cellular network where each bytes of usage would cost some penny, using as little volume as possible is important.
