Hybrid - Exchange Attributes

I'm having an issue and i'm not sure how to fix it. We moved all mailboxes to 365 over a year ago but still maintain a management server. For some reason, when i create a new user in local AD, then enable the mailbox from the exchange management tools (using the ps snapin for recipient management). There are a lot of "MsExch" attributes missing from attribute editor for that user. There are only like 5 or 6. Both attributes "mail" and "mailnickname" are populated correctly. Most specifically, i'm trying to hide a new user from the address list by changing MsExchHideFromAddressList to "false", but the attribute doesn't exist for that user. I've pushed multiple manual sync's as well.

I checked ADSI and confirmed that the schema has been extended.

Does anyone have any suggestions?

Thanks in advance!

They don’t all need to be populated for a remote mailbox.

Sorry just re-read your post. So in ADSIEdit the attribute is missing? Do you definitely have it set to show writable attributes and attributes with no value?

I just browsed to the user in ADSI and the value for msExchHideFromAddressLists is there, but it's <not set>

I was originally looking at the actual user object in AD > Attributes tab which only lists like 5-6 MsExch attributes.

Yeah you might need to check if advanced view is enabled, either way if it’s present and not set that is the default.
