Solved: User won't hide from Global Address List GAL in Exchange 2007 | Experts Exchange (3)asked on

Hello, we are running Exchange 2007 and we are having an issue hiding former users from the global address list. I wasn't able to find any other threads about this but we go into the user’s properties and select "Hide from Exchange address lists" but the account will not disappear on the gal. We are running a single domain and I have checked to make sure "Hide from gal" was both checked in Exchange and AD which it is, but the accounts are still showing up. Any thoughts?

I hope this helps,


Once you have checked Hide from Exchange Address List, you have to update the Global Address List to make the user disappear.

Run the following EMS Script to update your GAL

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Thanks, I have marked the option to "hide" on both AD and Exchange, but it will not go away, and this has been months ago since I told them to hide but refuse to. I have run the cmd update-globaladdresslist and it runs but gives me a warning that "Offline Address Book is invalid and could not be updated".


The following command will return all mailboxes marked as "Hidden from address list". Use it to confirm the users you want hidden are really configured as hidden.

get-mailbox | WHERE {$_.HiddenFromAddressListsEnabled -eq $True} | ft Displayname, HiddenFromAddressListsEnabled

Let me know if you get something interesting out of this command.

So then the problem seems to come from the address list itself. First, I need to know how many Address List do you have?

Then, update those AL
Get-AddressList | Update-AddressList

Do you still get the error? If no, verify the Offline Address Books

Get-OfflineAddressBook | FT Name,AddressLists
What address list is it associcated with?
Try to update the OAB by running an update only on that OAB

Provide any error you are getting.

Martin Gagnon, MCSA, MCITP:DBA, MCTS:Exchange Server 2007, VCP



Thanks Martin, when I Get-AddressList | Update-AddressList I get the attached errors

also in the even viewer:
Event ID 9360
OALGen encountered an error while generating the changes.oab file for version 2 and 3 differential downloads of address list "\Global Address List". The offline address list has not been updated so clients will not be able to download the current set of changes. Check other logged events to find the cause of this error.
If the cause of the problem was intentional or cannot be resolved OALGen can be forced to post a full offline address list by creating the DWORD registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA\Parameters\OAL post full if diff fails" and setting it to 1 on this server. When OALGen next generates the offline address list clients will perform a full OAB download. After that time the registry key should be removed to prevent further full downloads.


Event ID 9340
A new parent Legacy Exchange DN container value '/o=company name/ou=Exchange Administrative Group (************)/cn=Recipients' was found during generation of the differential update file for offline address list '\Global Address List'. This will force clients using this offline address list to do a full download of the offline address list.
- Default Offline Address List




I guess this setup is an update from 2003, right? If so, do you still use Exhange 2003?

To my knowledge when we migrated we had a clean install of 07 on a new server, ran them parallel and then migrated the boxes over. We do not currently use 03, but at one point 03 was still running on our network because our BES server needed it until we upgraded to the latest version of BES.

When you say you ran the OAB update do you mean you ran the Update-OfflineAddressBook EMS command?

Found another:

Event 9327
OALGen skipped some entries in the offline address list '\Global Address List'. To see which entries are affected, event logging for the OAL Generator must be set to at least medium.

I went into ESM and right clicked the offline folder and clicked "update"

Have you corrected the entry? If yes, have you updated the AL and the GAL? Do you still get the error that some objects are invalid?

Please restart your mail client and verify if the desired users are hidden now.



They are still in there, I also did a send/receive, download address book



Ok for fun I wanted to Re-enable the user and unhide it from the address list (to try and rehide the user) and this is the error I got when I tried to apply the settings

After I fixed that error in the update-offlineaddresslist I did what Martin said and updated the GAL and OAB at first the users did not disapear, but I went into Exchange and unselected the user from being hidden, applied the settings then re-added them as hidden, went back into the shell updated the GAL and OAB and the user was now hidden.

Thanks Martin!


"I went into ESM and right clicked the offline folder and clicked "update"

The above worked great for me. It failed but in failing it indicated to me that the Exchange System Attendant Service was not running. Started up the service and then was able to succesfully update the offline folder.

Followed that up with a fresh download of the Global Address book from the Send/Receive option in Outlook and the Global Address book was back to normal. No longer showing hidden mail boxes. Thank you!
