Hi friends, I have a number of users to whom I have added a work environment through a terminal server (in addition to a computer at work).
When they open Outlook in the terminal, Outlook starts sending a lot of old emails of the users,
Even 7 years back emails.
Even though I emptied the sent emails folder.
On the PC at work this does not happen, only in the terminal.

Anyone have any idea?
