So you'll be forced to get a TMP-device just to use M365, a piece of software you already use on another device for years?
That means that Office 365 will have to get the boot.
As an 'oldie', I can remember when every office computer had to have .doc capability. I haven't seen a .doc file (including .docx) for years. Everybody uses .pdf these days. Why? Simply because there's no bullshit about reading or writing .pdf files.
