Service Accounts

In order for the Email Signature Manager Service to be able to write Outlook signatures and deploy OWA signatures to user mailboxes, using Exchange Web Services (EWS), it is necessary to create an appropriate service account on Exchange Server. The details of this account (or accounts if you have a hybrid environment) are then entered in the Environment Configuration dialog.

•If you are using On-Premises Exchange Server, create an account using Active Directory User and Computers on a domain controller and then assign it the appropriate rights depending on the version of Exchange Server you are using:
 
è On Exchange Server 2016 and 2019.
è On Exchange Server 2013.

è On Exchange Server 2010.
è On Exchange Server 2007.

 
In addition, if you are using Exchange Server 2010 or higher, please read this topic on Exchange Server Throttling Policies.

•If you are using Hosted Exchange, you will need to contact your hosting provider and ask them to create an account with the appropriate permissions.
 

•If you are using Office 365, please read this topic to create the account through the administration portal.

Note If you have selected the Exchange without Impersonation Account option in the Environment Configuration dialog, then you do not need to create any service accounts. However, selecting this option, OWA signatures will not be deployed, and automatic support for Outlook signatures for remote users will not work.
