exchange 03 running out of space, trying to move all new users to a new store that was created. trying to migratte over all the users to the new store but a lot of them have a lot of memory that they are taking up up to 5gb. when trying to move them to the new mailbox its not always going smoothly and it also take a lot of time. without doing the offline defrag to also find out how much space is actually left on the drive is there anything else that i would be able to do to. any ideas would be greatly appreciated.
