Is there any other way or method of gathering inactivity reports other than going to the Office 365 portal in reporting and exporting Office 365 active users? How accurate/reliable is the data in this for last activity in exchange, skype, sharepoint, etc.?
I also ran this PS script, but this only give me the lastlogon time/date stamp of the mailbox:
My goal is to manage 30k users, and clean up licenses that are no longer needed by 90 days of inactivity. This would include all aspects of the license: mail/exchange, skype, sharepoint, access any of the online apps such as word, excel, powerpoint, etc.
Appreciate any direction anyone can point me in!
