Onedrive as a central storage for a small business

Once a day I've found I can't enter to any MS service of my BUSINESS account with any ID, incl. OnDrive cloud storage where I still have a lot of working files like contracts, drawing, notes etc. And there's ONLY working files as some of the files and directories are shared with partners I seeked technical assistance but get the cloudy response: "We examine new government mandates thoroughly to be certain our compliance does not impact a customer beyond what is required by law. ******.onmicrosoft.com has been identified as subject to mandates and we're obliged by law to take action. Our legal team is required to follow a government mandate process to identify and suspend service. If you require any further information on this I recommend you seek external counsel.
