This could have two possible causes:
The **Access Connect Service** on the server is not running with the relevant permissions. We always recommend using the Domain Administrator account. Ask your IT team to set the **Access Connect Service** to run with a server profile account with full domain admin permissions, such as the **Domain Administrator** account.
The Database has not been synchronised / linked with Workspace for the user. Within the Access Supply Chain database, the User Record attempting the process should be set so their Linked User is set with their own Workspace Account for the Set ADM User.
Note: If they have multiple databases, we need to link all databases for the unauthorised error to disappear.
To fix this, go into Access Supply Chain and link the accounts with Workspace:Click **System**, **User Records**.
Search for and select the required user.
Open the user record.
Click **Linked Users**.
Enter the **Workspace credentials** and select **Set ADM User**.
Click **Save and Close**.
