Scan accounts must have the ApplicationImpersonation role assigned to enable the scan engine to scan user mailboxes within the Exchange mailbox database(s). If you are running Exchange Server 2010 or later version, a new unlimited EWS Throttling Policy is created for the user account. Ensure to configure the EWS Throttling Policy for the scan account to avoid too many operation requests by ESET Mail Security, which might otherwise cause some of the requests to timeout. See EWS Best Practices and Understanding Client Throttling Policies articles to learn about the Throttling Policies. Also, see Change user throttling settings for specific users article for further details and examples. |
If you want to assign ApplicationImpersonation role to a user account manually and create new EWS Throttling Policy for this account, you can use the following commands (replace ESET-user with an actual account name in your system, you can also set limits for the EWS Throttling Policy by replacing $null with numbers):
