Issue :-

unable to move certain users to the new Pool. AD-Permissions on these users are inherited.

I'm getting the following message inside of the Power Shell when trying to move:

PS C:\Users> Move-CsUser -Identity "user" -Target "newpool"

Confirm

Move-CsUser

Solution:- go to the old pool server try Power Shell command to move the user to the XYZ-pool first. Then move it to the oldpool. Now you can run the original command of moving user from old pool to the newpool

Solution :-

This issue is caused due to the certificate miss-match or absence of required certificates.

it showed that the Public certificate had issues and need to reinstall the same. It is due to deletion of the root cert (internal CA1). Reinstall the certificate and restart the services. Please make sure all the edge external services FQDN in the public certificate SAN list. You can have a try to reinstall the public certificate again. Delete the external public certificate from the Edge server certificate folder in MMC. Then import Certificate again in the Certificate Wizard and assign the certificate to the External Edge interface. If the external services port is grabbed by other application, it also would cause this issue. Please have a check.
