Does anyone know the maximum storage you can hold for a single mailbox?
Answers:
it mostly depends on the hardware resources (diskspace) you (the admin) can set boundaries within exchange admin however.
Standard Edition have a database store hold back of i believe 18gig. Enterprise edition have no mark out.
There is no maximum decrease for the mailbox surrounded by Exchange 2k3, the GUI will permit you set the mark out upto 2Gb, however using ADSI gag you can remove this time limit and set your own if required
Whatever the admin sets. If in attendance are no confines next it's the size of the storage wall.
