I have tried to look for a solution, but I haven´t found one.
Setup is like this. 2 servers running win2k (as base OS) with Exchange 2003. Running smoothly. With 100´ish mailboxes.
For a long time clients have only used Office 2003. We have now started to deploy Office 2010.
We have a GPO that makes Outlook2003 empty the deleted mails folder in Outlook on exit. This works for the Outlook 2003 clients, but not for the Outlook 2010 clients. I asume this should be possible, But I can´t find any on this.
