So we have a user that is not showing up in the Global Address List. I made sure the hide from address list checkbox was unchecked, and set to false in ASDIEDIT. I also checked the showInAddressBook value, which was blank.
After copying the correct showInAddressBook value from another user, I am able to find that user in the GAL. Another search in the GAL and the user no longer shows. Looking at the showInAddressBook value again, it is blank. I am making the ASDIEDIT changes on the exchange server itself.
Any ideas on why the value keeps going blank on me?
