Using work email to use in personal devices. Any risks or things I need to know?

I stopped using Microsoft office after graduating from university which gave me access to office365.

Been using just google docs for 3 years now until I started working on a company which I can use my work email to use office365.

Apart from losing office365 subscription if I stop working with this company, are there any risk and disadvantages I should know when using with my personal devices?

Can they access my files? (Not gonna use cloud storage to save personal office files)


Can they see the history of files I open?


Other stuff I should know?

Don’t particularly care about cloud features that allow me to access files seamlessly across multiple devices.
