The reason boot.win doesn’t boot is because the Dells are too new and missing network drivers.

Solution: install the following network drivers from
​https://www.dell.com/support/kbdoc/en-us/000109842/dell-command-deploy-driver-packs-for-precision-models

Very important: after adding three drivers in wds, and enabling them, do not forget to right click on the boot image and add the drivers there, so the boot image to rebuild including the network drivers.

Close Outlook 365.
Go to folder

• ~/Library/Group Containers

Erase directories:

• UBF8T346G9.ms
• UBF8T346G9.Office
• UBF8T346G9.OfficeOsfWebHost

Empty the trash bin.
Start Outlook 365.
Make sure when you are using MFA, you are using MS Authenticator for confirmation, not SMS code. If you use SMS code to confirm MFA, you'll end up with the same problem.

And a close up of the pin (the little marks around it are where I was trying to hit at it with a hammer and flathead):

It took me a new bottom hinge ($40 from LG’s website, p/n AEH75957701 Center Hinge Assembly) to learn how. Simply make sure your 1/4” hex range goes all the way in the hinge’s pin and unscrew it as a regular screw. That’s all. On the photo is my original hinge which I managed to unscrew with an ease, after I knew what to do. The manual has to read “unscrewed like a regular screw” instead of “loosen”.

to put an existing image in oobe mode, press windows key + R and type

%windir%\system32\sysprep\sysprep.exe /audit /reboot

​after rebooting, check options "generalize" and "shutdown", delete all existing users from "advanced system settings/profiles" first, and then from "users" with "computer management", and proceed with the commands below:

run "disk cleanup"

from cmd run:

dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase

shutdown the vm using the sysprep program, change the boot order to boot from winpe, boot winpe. from diskpart assign A (the disk you will capture from) to the source, and B to the target (the disk where you'll put the .wim on).

The configuration below took me a bit, so I am putting it down to save you the time I spent.

You have to have a running Apache2.4 with mod_ssl and, configured SSL certificate in place already.

Below is the conversion matrix you need, in order not to get confused.
​I used LastPass to generate my password, but using anything else is fine.

Use yum to install these libraries and mod_auth_openidc

yum install jansson hiredis mod_auth_openidc jose

Below are my Azure AD parameters followed by my exact working auth_openidc config. It is placed in my "/etc/httpd/conf.d/auth_openidc.conf". The config file, begins with "OIDCProviderMetadataURL" =]

Below is how you add a connector (app registration)

These are the configuration settings in Azure Ad once you add the connector above.

This is how you get all the values you need. Just copy and paste them.

That URI below and the one in the apache configuration have to be the same.

Just add new client secret and Azure AD will generate a password for you, which password you will use in the apache configuration.
