Using a domain account to load MailSite Services To use a domain account to load the MailSite Services (instead of a local account) you will need to ensure the account has the following privileges:

• Log on as Service. This is under Group Policy Object Links > User Rights Assignment
• If you are running ExpressPro and associated services, then the account needs to be a member of IIS_WPG
• This account needs to have read/write permissions on the MailSite installation folder
• This account needs to have modify permissions on the BOX, Spool and Logs folders

As well as setting the MailSite services to log on with this account, you will also need to change the anonymous user within IIS for the various virtual directories (Express, ExpressPro, WebCal, WSS, Microsoft-server-activesync, and Pocket. You will also need to change the Application Pool called ExpressPro to use this domain account.
