Powershell 7 and Exchange Online MFA

VasilMichev That's the irony here -- ACS only supports the active tenant you're working with and only supports PS 6.2 with no way to modify, while also requiring cloud storage commitments (no purist O365 management).   I admit the costs are small but that's not really the point.

The REST commands are useful but are so limited as to be not relevant here; it's really about connectivity and viability to a tenant.

I would consider ACS a moderate step to the end goal if I could use a personal ACS to remote into others, but that is not possible in any ways I can find.  

I appreciate the work that MS is doing in this area but it seems like there's no conversation in this space - you simply can't authenticate into EXO from PS 6 or 7 on Windows (Modern auth).    I believe I could probably get this to work without using modern auth but that seems like a horrible step backward, which is why I'm trying to shake this tree.
