Connecting to the internet frequently is crucial for receiving automatic upgrades and making sure that your Microsoft 365 version is up-to-date. Failure to connect to the internet after 39 days will result in reduced functionality mode, and you will see an “Unlicensed Product” error in the title bar. To benefit from automatic upgrades and keep your apps current, you should connect to the internet frequently. Your programmes will enter a reduced capability state, and you can get an unauthorised product error if you don’t connect to the Internet at least once every 39 days. Simply sign back into Microsoft 365 after you’ve reconnected to the internet to activate your Microsoft 365 applications.
