This was definitely a first for me.
Hmmm, who knew that ten phones was too many?

Subject: Error with your new mobile phone partnership
You have 10 phone partnerships out of the maximum allowed 10 partnerships. After you reach the maximum, you can’t create additional partnerships until you delete existing ones from your account. To do so, sign in to Outlook Web App, click Options > Phone > Mobile Phones, and delete any unused partnerships.
