You can still use office365. It's just that the cloud-based M365 shouldn't be used. TBH, i used to work at a bank (and now at an energy company), and anecdotal evidence i have is that no big business use M365 cloud services(2 for 2 now). At least not in the IT departement, even where we have people using access to mash .xlsx together and get actionnable data from it. [edit] I must add that the bank used azure (as an AWS backup mostly), and still, we had no M365 product installed on our microsoft computer. I'm not a hater or anything, i do have a FOSS bias, but i try to stick to the facts here.
