# ImpersonateMailboxOwner

The user that connects to the Exchange Web Service (as specified by the `Username` or `WSUsername` parameter) must have permission to read messages from the mailboxes that you want to index.

To grant this permission, use one of the following methods:

- In Exchange, grant the user permission to impersonate other users. Then, in the connector’s configuration file, set `ImpersonateMailboxOwner=true`.
- In Exchange, grant the user full access permission on each mailbox that you want to retrieve. Then, in the connector’s configuration file, set `ImpersonateMailboxOwner=false`.
- In Exchange, grant the user “Reviewer” permission to each folder in each mailbox that you want to index. The user must have this permission on all folders below the root of the mailbox (or the folder specified by the connector’s `BaseMailboxFolder` configuration parameter). If the user does not have permission to access a mailbox folder, that folder and its contents cannot be indexed. In the connector’s configuration file, set `ImpersonateMailboxOwner=false`.
