Agree completely with @Armen. Continue to have the same issues after installing RU3. Can someone from MS please report whether this is fixed or not, and if it "has" been fixed, why it continues not to work.
Same scenario as before. User on Outlook 2003/Exchange 2003 (Online mode). 10 e-mails in Inbox, deleting one-by-one, all move to Deleted Items and nothing remains in Inbox.
User on Outlook 2003/Exchange 2010 (Online mode). 10 e-mails in Inbox, deleting one-by-one, all "move" to Deleted Items (no. of items updates) but some (usually 3-4) remain in Inbox and do not move. Subsequent attempts to delete result in "Unknown Error" and attempts to open in "Can't open this item".
I have tried EnablePushNotifications registry entry at 0 or 1 with no difference in experience.
Can someone from MS please comment on this specific issue.
