maximum exchange partnership exceeded – how to solve

with a lot testing with mobile device, i reached again the maximum number of allowed mobiles devices to sync with exchange environment via active sync

You have 100 device partnerships out of the maximum allowed 100 partnerships. After you reach the maximum, you can’t create additional partnerships until you delete existing ones from your account. To do this, sign in to Outlook Web App, click Options > Phone > Mobile Devices, and delete any unused partnerships.

when logged in via webmail it is possible to remove the paired devices via selfservice, unfortunately it is just possible to remove each device by itself in a not very performant ui

exchange mobile devices

as an admin there a other ways to get around this limitation via powershell

change the limit and increase the number – execute Get-ThrottlingPolicy | Set-ThrottlingPolicy -EASMaxDevices 20

programatically remove paired mobile devices Get-MobileDeviceStatistics -Mailbox "tonysmith" | Format-Table DeviceType, FirstSyncTime, LastSuccessSync, Guid
