We have a user that has Hide from Global Address List (GAL) set to 'yes' in Exchange Admin Center.
When I set to 'NO' and save I get "Operation Failed"
I checked the "msExchHideFromAddressLists" attribute on our on premises AD and that attribute isn't even listed.
We don't have an on premises Exchange Server
I'm stumped any help is appreciated.

Hi @Dan Smart ，
When I set to 'NO' and save I get "Operation Failed"
Is there any other error aside from "Operation Failed"?
Any luck if you try using the EXO powershell?
Set-Mailbox -Identity User@contoso.com -HiddenFromAddressListsEnabled $false
Ok, are you using AADConnect to sync from on-prem to Azure? If so, then the only way to make that work is add the Exchange schema by this method ( and then refresh the AADconnect schema in the AADConnect Wizard)
or not sync from on-prem.
Sorry, I've been focused on a different issue.
We don't use AADConnect (that I'm aware of). we are using the Microsoft Azure AD Sync running as a service.
Was Exchange ever installed? Its not supported to remove it from -prem unless you meet certain requirements if you are syncing with AAdConnect.
If Exchange was previously installed, then that attribute should be available. If are not seeing it on-prem, it could be just your filter view of that account. Make sure the view is set to show all values - even ones that are blank.
We have never had an on premises Exchange. I did filter the the Attributes to "all" and there isn't "msExchHideFromAddressLists"
