"The folders you are trying to change do not support this operation" error occurs in Microsoft Dynamics CRM

  • Article

This article describes a by design behavior that when you try to remove a Microsoft Dynamics CRM item that is added as a follow-up item in Microsoft Outlook, you receive the error "The folders you are trying to change do not support this operation".

Applies to:   Microsoft Dynamics CRM
Original KB number:   2502954

Symptoms

This issue can occur if you follow steps similar to these:

  1. In Microsoft Dynamics CRM Client for Outlook, right-click on a Microsoft Dynamics CRM record (For example, Contact).
  2. Choose Follow Up to add an Outlook Follow Up item to the ToDo Bar.
  3. Next, switch to another Entity like Accounts or Opportunities.
  4. Attempt to delete the Follow Up item from the ToDo Bar.

The following error will occur:

The folders you are trying to change do not support this operation. Could not complete the operation because the service provider does not support it.

Cause

MAPI event listeners only listen to the folder events for the current grid that is displayed. If you switch to a different entity (account) and you're trying to delete a contact you'll get this error.

More information

This is by design as the MAPI event listener does not listen on all folders for performance reasons. If you want to delete a record from the ToDo bar in Outlook, you need to switch to that entity type.
