Spanning automatically refreshes the user list once per day to search for new users in your domain. If a user was recently added to your domain, and Spanning has not yet run this user refresh, this new user won't appear in the License Manager. To have these new users show up immediately, initiate an on-demand user refresh by following the steps below:
1. Log into your Spanning License Manager by visiting http://www.spanningbackup.com/manage.
2. Click the circular arrow button in the upper-right corner of the user list. This will repopulate your Spanning user list directly from your G Suite user list. Your newly added users should now be listed in your License Manager, and will be available to assign a Spanning Backup license to.
