This article describes how to change Office Apps license type:

Note: it is not possible to have Office Apps and Office Apps ProPlus licenses assigned to one user at the same time.

Changing License Type in CONTROL PANEL

In order to change licenses, login to CONTROL PANEL with your administrator's credentials and navigate to Services > Smarsh Hosted Services Office Apps > Users.

Control Panel

To Unassign the Licenses

  1. Go to the Users section and select the target users 
  2. Click Unassign licenses from selected... button
  3. Choose Office Apps > click Save changes button

Control Panel

Note: end-user data should not be lost on the license unassignment if the account remains without a license for less than 30 days. After 30 days an unassigned end-user account is deleted. If no licenses are assigned, Office will have reduced functionality and most features will be disabled.

To Assign the Licenses

  1. Go to the Users section and select the target users 
  2. Click Assign licenses for selected button
  3. Choose Office Apps ProPlus > click Save changes button

Control Panel

Note: In case you decide to change the Office license type (e.g. upgrade from Office Apps to Office Apps ProPlus), there would be no need to reinstall the Office applications. The Office will keep working as expected even after the license change.
