Frequently Asked Questions

Why is Microsoft 365 asking for a product key during my free trial?

This usually happens if the pre-installed version of Office on your device does not recognize your digital trial license, or if you are signed in with a different Microsoft account. Downloading the installer directly from the account linked to your trial resolves this.

Can I access the Excel Developer tab on the web version of Microsoft 365?

No, the Developer tab and advanced features like VBA (Visual Basic for Applications) and macros are exclusive to the desktop version of Excel. You must download and install the desktop app to use these features.

What happens to my desktop apps when the Microsoft 365 trial expires?

Once the trial period ends, the downloaded desktop applications will enter a reduced functionality mode. You will still be able to view and print documents, but you will not be able to edit existing files or create new ones until you purchase a subscription.
