How to cancel ModernSync

Updated 13 October 2026

You cancel in the portal yourselves. Offboarding stops all runs, and you get no more invoices. It cannot be undone, so if you only want a pause, tick Test runs only under Settings instead.

1. Choose what happens to the contacts

Go to Settings and click Offboard under Administration. The dialog asks what should happen to the contacts, and nothing is selected in advance:

  • Remove the contacts. Every contact ModernSync has created is removed from the recipients’ mailboxes, and with them from the phones. Contacts the users created themselves are not affected.
  • Keep the contacts. The contacts are kept but no longer updated. New colleagues are not added, changed numbers are not updated, and people who leave are not removed.

If you use the calendar add-on, the calendars follow the same choice, and the options are called Remove contacts and calendars and Keep contacts and calendars. ModernSync only removes the calendars it created itself. Users’ own calendars are not affected.

2. Confirm

Type your organisation’s name in the dialog and click Offboard. If you chose to remove the contacts, ModernSync starts a run that removes them along with any calendars, and you can follow it under Runs. When it has finished, Overview shows that the organisation is offboarded.

3. Remove the app in Microsoft Entra ID

Wait until the removal in step 2 has finished, because ModernSync needs its access to delete the contacts. Then open the Microsoft Entra admin centre, go to Enterprise applications, find ModernSync Contacts and delete it. If you used the calendar add-on, delete ModernSync Calendar as well. Microsoft then stops issuing access tokens to the app. If a run is in progress, it can continue for up to an hour.

Your data afterwards

After offboarding we delete the data we have processed for you, unless the law requires us to keep it. We do not store the contacts themselves, so there is nothing to hand back. Contacts you keep are your own data from then on.
