Re: How to save Outlook mailbox ?

[Patrik Dufresne]

Hello Alex,

/B required some extra privilege according to the documentation. Still I
tested it and it's failing as follow:

ERROR : You do not have the Backup and Restore Files user rights.
*****  You need these to perform Backup copies (/B or /ZB).


Elevated privilege is not always available and I cannot rely on it...

products to successfully back up.

Do you know such a product ? And how is it working ?
