Public Folder administrator mailboxes

Hi there,

I am looking at doing some public folder migrations from Exchange 2010 to Exchange 2013. As a pre-requisite, I need to create Administrator mailboxes. How do I go about doing this? Is it just an account with a mailbox? what permissions does this mailbox need to have? I am planning to use the same account that I use for the mailbox migrations for public folder migrations.

Quest documentation is not very clear on this and just says "Administrator mailboxes should be created on all Exchange servers". So in production, if I have 2 or 3 servers that have public folders in the source environment, do I need to create that many administrator accounts?

Any assistance will be appreciated. Thanks.


  • An Administrator's mailbox is just a mailbox hosted on the same server as the PFs, no special permissions. In the tools configuration it is used as the start point for the PF's that are visible to the job. So if you have 3 servers hosts public folders, will have 3 administrator's mailboxes, one on each server. That means there is NO way you can use the same account you use for the mailbox migration. This account is used for access, the mailbox is used for the MAPI profile for visibility to the data.
