Error message when using the new server-based SharePoint integration for Microsoft Dynamics CRM Online and SharePoint Online: "List Does Not Support This Operation"

This may be the result of a mismatch between the Display Name of the CRM entity and the corresponding Name of the SharePoint document library. 

To verify: Check the SharePoint website to see if the Display Name of the CRM entity matches the Name of the SharePoint document library.


Step 1: Check the Display Name of the CRM entity (Example: Opportunity)

1. In CRM, navigate to the Settings page.
2. Select Customizations from the Settings dropdown in the navigation bar.
3. Click Customize the System.
4. In the new window, select Entities from the left-hand column.
5. In the list of entities, select the desired entity (in this example, select Opportunity).
6. In the General section, look at the text shown in the Display Name field. This is the name that will be displayed for the CRM entity.

Step 2: Check the SharePoint document library Name (Example: Opportunity)

1. In the SharePoint website used for Document Management, navigate to Site Contents.
2. Select the document library that corresponds to the CRM entity mentioned in Step 1 (in this example, select Opportunity).
3. Select the Library tab in the ribbon at the top of the page. This will expose additional site actions for the library.
4. Click the Library Settings site action.
5. Select the List name, Description, and Navigation link under General Settings.
6. Look at the text shown in the Name field. This is the name displayed for the SharePoint document library.

The Display Name shown for the CRM entity in Step 1 must match the Name shown for the SharePoint document library in Step 2. If these fields do not match, this issue could occur.
