Behavior:
When attempting to access DocuWare for Outlook, the following error is given, 

"InteractionRequiredAuthError: consent_required: AADSTS65001: The user or administrator has not consented to use the application with ID 'fd6a5943-4e75-45a8-9044-52e5ceadf7aa' named 'DocuWare for Outlook'."

Solution:
AADSTS65001 error points to an issue with consent not being given to the user for the DocuWare for Outlook add-in. 

An Azure Administrator must consent to DocuWare for Outlook add-in from the Microsoft Entra page. 
Microsoft Entra admin center

Alternatively, a URL can be constructed to grant tenant-wide admin consent, which will provide the consent window when accessed.
