In 2021 I purchased a licence for Office which allows me to use it on 3 separate machines. It was installed on a Mac and is working fine. I have just tried to install it and run it on a MacBook Air. It has installed ok and although I can open each app it won't save any work, instead it asks me to subscribe to Msft 365.
Word opens but I can't type anything.
I've tried logging in to my account from the MacBook but it doesn't make any difference

2026-09-30T13:15:35.7933333+00:00 Yes, that is correct, you would need to purchase a new Office licence for the MacBook, and do not update Office 2019 on the Mac, because if you do, it would go into Read Only mode after that update they released in July.

Not good news then, if I want to use my laptop then I have to buy Office 2024?
Final question please. If I did that and didn't upgrade the desktop version would the versions be compatible? In other words could I create things on one machine and work on them or present from the other?

2026-09-30T13:04:55.4833333+00:00 I just re-read your details, if your Office version is 2019, then you will not be able to use Office on the MacBook, after an update released in July, it is no longer possible to update the security certificated on Office 2019, and Office would go into Read-only mode, they provide full details on that update on this link.
