Unable to delete contactFolder (getting ErrorCannotDeleteObject)

Question

Hello,

I'm trying to do a simple delete operation on the user contact folders.

It was working fine until last sunday (05/05/2024).

Since then, I keep getting the following error:

{
	...
	statusCode: 403,
	body: '{"code":"ErrorCannotDeleteObject","message":"Object cannot be deleted."}',
	...
}

I'm almost certain I have all the correct Read/Write permissions and that the ids I'm passing are valid.

Here is the method I use to delete the folder:

  public async deleteUserContactFolder(userId: UserIdentifier, contactFolderId: string)
  {
    return this._client.api(`/users/${userId}/contactFolders/${contactFolderId}`).delete();
  }

Thanks for your help

Hey Martin,

Not really.

I guess Microsoft simply does not like when we delete entire contact folders over and over in order to sync our users address books.

The cleanest solution is to delete contacts within the folder in batches.

You can delete up to 20 contacts in a single batch.

What I would suggest is either doing in two times:

• Get the list of contacts in the folder
• Delete all of them one by one in batches

or having a way to remember every contact you've synced and delete/update them in a smarter way.

Hope it helps,

Baptiste

this endpoints worked fine.

But

does not work.
