Win XP SP3, Office 2010, running on Exchange. We have many other users are running Office 2010 on XP SP3 fine.
I removed 2007 and installed 2010 to fix some other issues the user had (.doc and .docx attachments would not open and hung Office). All is well except the Sent Items folder is perpetually empty. However, they DO appear fro user when attached to Outlook Web Access. I can get the folder to display the number of items in the Sent folder, just not the actual emails. It's always completely empty when clicked on. This user has been known to fiddle with settings, but want to reinstall as a last resort. I'd also like to understand the issue should I encounter it again
TIA for any insight - the user I'm supporting could not be much more impatient and high-profile.
Edit: we use Cached Exchange mode. I've checked to make sure "save copy to Sent Items" box is checked.
