I have a user that has a large Outlook 2007 OST file. It was over 4 gigs... We got it down to 1.7 gigs. The problem she is having is anytime she logs into OUtlook 2007 it always starts out by updating Inbox with 150MB of data.. regardless if there is emails to be downloaded or not.. Currently using Cached mode... Cannot use online mode with our current internet speeds. She has to constantly click send / receive to get new emails to download or exit outlook and log back in.. when she does this it still looks to download 150MB of data. Please advise.
