Office 2016 has suddenly become Office 365. Is this normal?

Until recently I had Office 2010 installed on my laptop, but after serious software problems, the technician at the university department where I work replaced it with Office 2016.
Last night I added some additional language packs to Office, and then noticed when I started up Word and Outlook this morning that instead of seeing Word/Outlook - Office 2016 I now get Word/Outlook - Office 365. Is this 'update' normal? And am I going to have to pay every so often to maintain Office 365 (I read somewhere that it is not an upfront payment like Office 2016, but a type of subscription service).

I'd check with your I.T. person to see what was purchased.

Whats the difference between Office 365 and Office 2016? - Office 365

Thanks for the reply, Berton. The version originally installed on my laptop was Office 2016; it was under licence to the university I work for, and has been installed on various PCs in my department. I obviously paid nothing for it. I have just checked out Office 365 (thanks for the link), and it is in fact a subscription service. I didn't request an update, and was happy with Office 2016. As far as you know, is it possible to go back to the previous version?

Is there a problem with your Office 365? Have you tried opening an Office application while not connected to the Network and Internet? The only issue I've seen, on a client's computer, was he had to sign in at least once a month to keep it activated. Again, it may depend upon what was purchased, most companies and institutions will get the Enterprise pricing to cover a large number of computers.

Many thanks for your feedback, guys. No, I don't think there are any problems with Office 365, but as I mentioned earlier, I've only had it since this morning!
I do not have a personal Microsoft account, so it will be interesting to see what happens after a month. But precisely because I don't have an account, I can hardly be expected to sign in. I'll just have to assume that the university will handle the expenses!
