Dynamics 9.1 on-prem -> Sharepoint 2019 on-prem: Server-based integration

Posted on by 55

Hi all

I'm trying to connect my dynamics 365 organization with a SharePoint 2019 instance.

I was going step by step following the instruction from the MSDN (

There we no errors, everything was successfully, but as result, I got the 401 exception (The remote server returned an error: (401) Unauthorized.)

I've found a lot of solutions in this community regarding it but they didn't helped

All the prerequisites have been met. A domain is the same. ADFS is 3.0

User in the CRM already has the sharepoint email field and value.

When I'm trying to validate the SP site in the Settings -> Document Management -> SharePoint sites, I'm getting the same error.

Here is my PowerShell script on the SP side:

    Hi Michael.

    Have you configured User Profile Service Application within SharePoint?
    Be sure that the "work email" is set on on the user's profiles and matches the SharePoint Email Address field in Dynamics 365.

    If you have already done this I would recommend you check the SharePoint ULS log when you've reproduced the 401 Unathorized error.
    It's quite simple to see what is missing there and if i recall correctly the SP correlation id is in the error so you can just copy that from Dynamics 365 and search for all corresponding entries and you will see why SP throws the 401, and if not just go for "401" or the "mail/upn" you have for the user reproducing the error which is the SharePoint Email address field mentioned earlier.

    Hope this helps.
