I think I know the answer to this, but I thought it would be worth posting anyway.

I have a BB7100R with 4.0 OS and BES 4.0 doing all the OTA stuff and I really like it. The problem I have is with syncing my e-mails with outlook. It works fine under a high-speed connection to the network, but on a dial-up connection, I see a whole bunch of re-syncing going on - for example, I'll get an e-mail with a 2-3MB attachment and flip it open on the BB. It will come into Outlook as a header (unread), download the attachment and become a usable e-mail, then shortly after that, it will turn into a header e-mail and re-download the attachment.

Is there anything I can do to stop this from happening? On a dial-up, it's a bit of a drag. I'd like to keep Outlook Cached Mode as it's great for being offline and I'd rather use it instead of offline folders.

Any suggestions?
