How to grant FullAccess Rights in BPOS (Business Productivity Online Services) (90189)

To migrate data from BPOS, your administrator account must have FullAccess rights to each mailbox that will be migrated

If you have not already done so, download and install the Microsoft Online Services Migration Tools toolkit.

To grant FullAccess rights in BPOS you will need to use Powershell:

1. Open a Powershell command prompt and add the Powershell snapin for the Microsoft Online Services Migration Tools by running the command:
   Add-PSSnapin Microsoft.Exchange.Transporter
2. Use the Add-MSOnlineMailPermission cmdlet to grant the appropriate admin user(s) the GrantFullAccess and GrantSendAs rights.
