Service Accounts

In order for the Email Signature Manager Service to use Exchange Web Services (EWS) to write signature settings and deploy OWA signatures to the users in your organization, 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.
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.
