Error While Adding User to a Group

While adding a user to a EUM Group, an error message might be displayed. There might be several reasons of the error message:

1. The user is already a member of the group
2. The user could not be added to the SharePoint group associated with the EUM Group

The user could not be added to the SharePoint group associated with the EUM Group

This can happen due to a few reasons:

1. The SharePoint site is not externally shared
2. The SharePoint Site Collection URL added to the EUM Group is not acceptable to the EUM Group
3. The SharePoint Group added to the EUM Group has a typo

The SharePoint site is not externally shared

For EUM to be able to add users to the SharePoint Group belonging to a SharePoint site, the SharePoint site should have external sharing ON.

1. Please login to the SharePoint Admin as an admin
2. Search for the concerned site
3. Click Sharing in the top menu
4. The External Sharing should be set to "Existing guests only"
   

The SharePoint Site Collection URL added to the EUM Group is not acceptable to the EUM Group

The SharePoint Site Collection URL added to the EUM Group must be the URL to the site, and not to any page of the site

The SharePoint Group added to the EUM Group has a typo

The SharePoint Group added to the EUM Group could have a typo, an extra space, or some formatting carried over from SharePoint if copied from there.
