Ever since we installed Exchange 2003 we have noticed when changes are made to a mailbox the changes do not show up right away. Usually if we wait overnight then things work as expected in the morning. Is there some type of overnight processing which has to occur before changes become active.
For example, adding a different user to a mailbox permissions. The user has to wait till next morning before they can access the mailbox.
It is not a real problem but we are curious about the delay.
