The www.microsoft.com/exchange web team and PSS put together a page with links to a bunch of other sources of information about mailbox management in Exchange 2003:
New e-mail meassage tool bar:
What does Do not deliver before actually mean e.g. I could enter 10 June 2000 23:00. the wording could mean deliver in 2 years time!!! or 1 years time or anytime not before the stated date. It does seem a perverse wording e.g why could it not say Deliver at 10 June 2004 23:00 then we would know exactly when to expect it to go.
You views/adviuce on this would be most appreciated.
