Can't activate Microsoft 365 (purchased) on new Mac

A few years ago, I bought (outright purchase, not subscription) Microsoft 365. I have recently changed computers from a seven-year-old model running Ventura to a new M4 iMac running Sequoia. I cannot activate Microsoft on the new computer.




If I open the Word or Excel program and then select “About word” or “Activate office” from the File menu, I get a message that says “Licence not activated” but does say “Belongs to:” with my email address and also shows a product ID and a session ID. It invites me to refresh. But if I try this sometimes it will not accept the email address which it has indicated is mine, sometimes it will say “loading” and then go on loading forever.




If I open a Word file I have previously created, it cannot be edited or saved. There is a message "action required. We’ve detected a one time purchase licence. This licence can only be used with Microsoft 365 apps downloaded directly from Microsoft 365.com. 




So I go to the Microsoft 365 site and login. It accepts my email address and the associated password, but lists me as having no products. I have followed all the instructions I can find but just go round and round in circles. There seems to be no provision for speaking to a human being by telephone or sending an email.




Does anyone have any suggestions?

iMac 21.5″ 4K, macOS 13.7

The version you have may not be compatible with Sequoia on your new Mac.


It would help if you can identify the exact version you purchased and when/re/how you purchased it. Are you sure it was Microsoft 365, not Office 365 or Office 2016, 2019 or 2021? "Office" versions were one-time purchases. "365" versions, afaik, have always been subscription, and certainly are only that today. I do not believe there is any option to convert a one-time purchase version to a subscription plan.


Also, did you migrate the app from your old Mac, or do a new install on your new Mac? If a new install, was it from disk or download?

There is no way to “outright purchase” Microsoft 365. It has always been a subscription service.

You can purchase Office “Home” or “Home & Business” versions.


If your Microsoft account says you have no active purchases (subscription or otherwise), then that account probably doesn’t have the license info. That account page will show all subscriptions and single-purchase versions you have registered with them.

You need to contact Microsoft to resolve that.

Many thanks to all three of you. You are all, of course, right: what I purchased, it turns out, is Office 2019. After a certain amount of digging, I find that I purchased it in September 2019 from Amazon. It was delivered as a download via an email. There is no kind of identifying number. I transferred the data from the old computer to the new via a Time Machine. This went smoothly, though there have been a couple of other apps which I have had problems reactivating, though these are now resolved.




If I open Word or Excel and select About Word or About Excel, it shows the version as 16.29 and says “Belongs to:” with my correct email address. There is a Product ID but this is just a row of zeros. There is a Device ID of 32 characters.




I find that, whatever I google, it leads to Microsoft 365 rather than Office. And I’m asked for a Product Key, which I don't appear to have been given. I'll persevere.
