Observed behavior: The apps can be used offline to edit locally stored files, provided the device connects to the internet at least once every 30 days to validate the license.

Manage Microsoft 365 Offline Usage and Validation

Follow these steps to ensure your Microsoft 365 apps remain functional when you do not have a continuous internet connection.

Microsoft 365 is a subscription-based service, which means it relies on periodic internet check-ins to verify that your subscription is still active. You do not need to be online to do your day-to-day work, but you cannot remain offline indefinitely.

Install the Desktop Apps

Log in to your Microsoft account at the official Microsoft services page and download the desktop applications to your local drive while connected to the internet.

Perform Initial Activation

Launch any installed Office application (such as Word or Excel). Sign in with your Microsoft 365 credentials to activate the software locally on your machine.

Work Offline and Save Locally

Disconnect from the internet. You can now freely open, edit, and create documents. Be sure to select 'This PC' or a local folder when saving your files, as saving to OneDrive requires an active connection.

Reconnect Every 30 Days

To prevent the software from locking you out of editing features, connect your computer to the internet at least once every 30 days. The Microsoft licensing service will automatically validate your subscription in the background.

Reduced Functionality Mode: If you fail to connect to the internet within the 30-day window, Microsoft 365 will enter reduced-functionality mode. You will still be able to open and print your files, but you will not be able to edit them or create new ones until you reconnect.
