Set up service users in SharePoint
You can only use service users if you do not use two-factor authentication to log in to SharePoint.
SharePoint Online
If you use SharePoint Online, you do not need to set up a special service user in SharePoint. In this case, a service account with no user reference is used automatically.
SharePoint On Premise
If you use SharePoint On Premise, you can define SharePoint users to be used as service users. You must enter the user names and passwords for these users in Intrexx.
You can find detailed information on this in the section Create service user for SharePoint On Premise.
