# Troubleshoot the Connector

This section describes how to troubleshoot common problems that might occur when you set up the Exchange Web Service Connector.

The Connector does not Retrieve a Mailbox

`ERROR: Unable to retrieve chosen root folder for mailbox: user@domain ... Server error message: Connection did not succeed. Try again later.`

`ERROR: Unable to retrieve chosen root folder for mailbox: user@domain ... Server error message: The specified object was not found in the store.`

If you encounter one of these errors, the user configured to access the Exchange Web Services might not have sufficient permissions to access a mailbox.

Permissions Error when using Impersonation

`ERROR: Unable to retrieve chosen root folder for mailbox: user@domain ... Server error message: The account does not have permission to impersonate the requested user.`

If you encounter this error, the connector is configured to retrieve messages by impersonating other users but the user configured to access the Exchange Web Service does not have permission to impersonate the owner of the specified mailbox. Consider granting the user permission to impersonate the mailbox owner. Alternatively, set the connector’s `ImpersonateMailboxOwner` configuration parameter to `FALSE`, and grant permissions to the Exchange user through a different method.

Error when Accessing Public Folders

`ERROR: Failed to process Public Folders ... Server error message: In order to access a public folder, the effective caller must have a mailbox.`

This error occurs when the user configured to access the Exchange Web Service does not have a mailbox and therefore cannot access public folders. To prevent this error, create a mailbox for the user. After creating the mailbox, you might have to wait for the change to take effect.
