LicReport365

Slowly but surely, the Office 365 dev team is adding reporting functionality to their platform, to the delight of admins and managers alike. For admins it means a lot less scripts to write, for managers it means knowing….stuff.

One report I missed was a report that tells me when users last logged on. Because if I have thousands of users, and they all consume licenses….I’d very much like to strip licenses from users that haven’t logged in since x amount of time.

Especially for companies with geographically dispersed users and inefficient exit procedures, this can save a lot of licensing costs over time.

My report was built in Powershell, and will check the last time the mailbox was accessed to determine the last logon date, this is not perfect, as I can image some organisations use specific licenses just for skype or dynamics, they will not benefit as much from this script, but in 99% of the times it should suffice 🙂

The script will list the user UPN, Name, Last Logon, Creation Date, Usage Location, Mailbox Size and Used Licenses.
