We've got someone VPNing in internationally and whenever they try to open their inbox in Outlook, the program sits in a busy state for nearly a minute before coming back.
There's no subfolders in the inbox and only less than 100 emails at any one time.
Switching between other folders is fine and snappy - even with thousands of emails, but when they go back to the inbox, the problem happens.
Cached mode is enabled and on slow connections, only the headers will be downloaded.
Does Outlook do anything special when the inbox is opened?
Thanks,
Andrew
