Thanks for this thread all. Having to rethink our upgrade to SP6 MR3. Some users already complaining about meetings going missing, can only imagine what would happen if things get worse.
A colleague found this doc to clarify MS stand on meeting request do/don'ts in Outlook:

Has anybody checked if the delegates have full access to the Deleted Items folder on their delegator's (?) mailbox? I tend to use the "DelegateWasteBasketStyle" registry key (in WinXP, Outlook 2003), hence the need for this level of access.
Glad we're not the only ones experiencing this problem.
