Description

I am consistently getting a failure when calling the Microsoft Graph API for contacts on my account. The API returns the following error:

API: https://graph.microsoft.com/v1.0/me/contacts

{
    "error": {
        "code": "ErrorTooManyObjectsOpened",
        "message": "Too many concurrent connections opened., Cannot open mailbox. Server = DM6PR17MB3772.namprd17.prod.outlook.com, mdbGuid = f792079b-96dd-4162-ae3d-a96effad59b2, maiboxGuid = 40f4b8af-4b87-4d37-9bd9-afab653e6544"
    }
}

Research direction

Start by reproducing the request to https://graph.microsoft.com/v1.0/me/contacts and record whether ErrorTooManyObjectsOpened occurs consistently. Then determine whether the failure is specific to Graph Explorer or the account; done requires a confirmed cause and a maintainer decision on whether a repository change is needed.
