I have Exchange 2010 setup. On the database we setup default storage limits for, for example issue warning at 400MB, prohibit send at 450 MB, and prohibit send/receive at 500 MB.
If I go into a user mailbox and go to where I can adjust the Storage Quota for that user, I uncheck 'Use mailbox database defaults', and then set my own limits for that mailbox. The limits I am setting do exceed the default limits, but that should not matter since I told this mailbox not to use the mailbox database defaults. When I adjust it to a greater value, I am still unable to send an email to that mailbox even after the limits are set greater than the current mailbox size.
Any idea on why I cannot override the default database storage quoats? Am I being impatient and is there something that runs to update this? Is this not an immediate effect?
