The list of users expiring soon can be reported from Users Generic Report (UGR) in Aptem Classic by pulling the Id, Full Name and Subscription End date fields.
Subsequently, filter for accounts expiring within the current year by choosing the 'is before' option under the filter settings for the 'Subscription End' field. Input the maximum date until which you wish to search, this will show the list of users expiring soon based on the date entered (as shown in the following screenshot). Finally, utilise the 'Quicksheet' function to export this report.
To prevent their expiration, please contact Aptem Support with the exported list of users due to expire and request an extension of their subscription.
