Exchange 2010 Mobile phone sync issue
"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."
I have checked this via OWA as advised, and via the Exchange 2010 Management Console, however there are only 3.
How can I fix this (also, I don't have access to my clients phone, so I'm hoping I can fix this server side)
