Frequently Asked Questions

Can I use Microsoft Project desktop with an Office 365 E3 license?

No, Office 365 E3 does not include the Microsoft Project desktop client. You must purchase a standalone Project Plan 3 or Project Plan 5 subscription to use the desktop application.

What is the difference between Project Plan 1 and Project Plan 3?

Project Plan 1 only provides access to the cloud-based Project for the Web. Project Plan 3 includes everything in Plan 1 plus the fully functional Microsoft Project desktop application.

Why does my Microsoft Project say 'Trial' when I have a Plan 1 license?

Since Plan 1 does not grant desktop access, downloading the desktop app will default to a trial version. You must use the web browser to access your Plan 1 features.

How do I check which Microsoft Project license I have?

Log in to your Microsoft 365 account, click on your profile picture, select 'View account', and navigate to the 'Subscriptions' tab to see your active licenses.
