When using Batch Faxing from a fax that is not connected directly to your computer, you must have a Microsoft Fax Server destination entered into the Microsoft Fax Server field on the File ? Company Info ? PO/Email/Fax tab. Example: DM-Domain2.
If you receive an error -214??Access denied? while batch faxing, be sure that the user is a member of the Local Administrators of the Fax Server. If the Server is also the Domain Server, then the user must be an Administrator of the Domain in order to send the batch faxes.
