Projects List

This is a list of some of the things I’ve been looking at. I don’t have time to write posts about them all, but if there are any that are of interest, let me know using the contact form below and I’ll write them up.

Comments are welcome; it would be nice to know if anyone actually reads any of this!

Currently (June 2021) you can’t have a CA policy that implements a ‘block all applications except’ rule without blocking MyApps and MFA registration. ¬†Using Powershell to access the Graph REST API, this keeps the polices up to date without having to list all the exclude apps manually.
