Exchange Security Groups not present in the Security of organizational units and on users


Goodmorning everyone,

I have implemented a coexistence between an Exchange 2010 and an Exchange 2016.

In doing the move on the DB of 2016 I have an error extended on several users related to the homeMDB permissions

Error: MigrationPermanentException: Active Directory property 'homeMDB' is not writable to recipient

The prepareAD did not give me any errors during the installation phase of Exchange 2016

I have checked the versions from ADSI and they are all up to date.

The Exchange Security groups all exist, also because an Exchange 2010 is already present in the environment

However, I realized that they are not present in the OU and user security

Some users, I was able to move them, as they had the correct ACLs and did not have active inheritance

By adding Exchange Trusted Subsystem, on individual user objects, I am able to make the move

I wanted to restore the permissions upstream, to act in propagation on everyone

Would it be enough to re-run Setup / PrepareAD?

Are there other solutions to be adopted?

Thank you

Hi, @ekos80fm-6298

As Andy said, PrepareAD won't reset the permission settings on specific user object if permission inheritance is blocked.
To fix it, you may need to Enable inheritance on the user object.

I suppose manually add the required permissions may also work but it is not recommended to modify the default settings.
