Exchange – New User(s) Not Showing Up On Global Address List

KB ID 0000775 Dtd 24/02/13

Problem

If you create a new user, give them a mailbox, and they seemingly fail to appear then don’t panic!

Create new user and mailbox

Firstly and fore mostly: If you do anything in Exchange: Apply the “cup of coffee rule”, never make a change then go and prove that change works straight away! check it later.

However most of us work in the real world and you have a user who needs to use this mailbox yesterday!

Bear in mind, the process you need to follow is;

1. Make sure the user does have a mailbox.
2. Make sure that user/mailbox is on the GAL.
3. Make sure the OAB you are looking at, has been updated from the GAL.
4. If using Outlook, query the GAL directly, or download the latest OAB.

Solution

Make sure the User Does Have a Mailbox

1. Before you do anything send the user you created a ‘Test Email’ from your own account. If you receive an error message then you can investigate further (Note: Set your Outlook client to send you a delivery report on the test email as well). Then check the mailbox Exists (See Check for existence of mailbox sections below).

OWA Request Delivery Receipt

Check for the Existence of the mailbox (Exchange 2000 /2003)

1. Click Start > All Programs > Microsoft Exchange > System Manager.

2. Expand the Exchange Organisation > Administrative groups > Administrative group name (First Administrative group is the default).

Note: If you cannot see Administrative Groups right click the Very top object > Properties > Tick Display Administrative Groups.

3. Expand Servers > Server-name > Storage Group (First Storage group will be the default) > Mailbox Store > Mailboxes.

4. The Mailbox SHOULD be in the right hand window (Providing you are in the correct administrative group, on the correct server, and in the correct mailbox store!).

Exchange 2003 Mailbox location

Check for the Existence of a mailbox (Exchange 2007/2010)

Remember with Exchange 2007 / 2010 you create the mailbox with the Exchange system Manager anyway!

1. On the Exchange Server, Start > All Programs > Microsoft Exchange Server 2007 > Exchange Management Console.
2. Expand recipient Configuration > Mailbox.
3. The Mailbox should be listed in the centre window.

Exchange 2010 Mailbox location

Check for the Existence of a mailbox (Exchange 2013/2016)

Connect to the Exchange admin center > recipients > mailboxes > locate your user.

Exchange 2013 Mailbox location

Mailbox is there but the user is not listed on the Global Address List

1. Make sure the user is not “Hidden from the Global Address List”

Exchange 2000/2003

On the Exchange Server > Click Start > run > dsa.msc {enter} >Locate the user in question > Right Click the user > Properties > Exchange Advanced Tab > Ensure “Hide from Exchange Address Lists” is NOT ticked.

Exchange 2003 Hide From Address List

Exchange 2007/2010

On the Exchange Server > Start > All Programs > Microsoft Exchange Server 2007 > Exchange Management Console Expand recipient Configuration > Mailbox > Locate the Mailbox for the user in question > Right Click the Mailbox > Properties > General Tab > Ensure “Hide From Exchange Address Lists” is NOT ticked.

Exchange 2010 Hide From Address List

Exchange 2013/2016

Connect to the Exchange admin center > recipients > mailboxes > locate your user > Edit > Ensure “Hide From Exchange Address Lists” is NOT ticked.

Exchange 2013 Hide From Address List

Make sure the user is on the Global Address List on the server.

The easiest way to do this is simply connect to Outlook Web Access, and query the GAL directly (OWA uses the GAL no the OAB like Outlook running in cached mode does).

Exchange 2000/2003

Click Start > All Programs > Microsoft Exchange > System Manager > Expand Recipients >All Global Address Lists > Right Click Default Global Address List > Properties > General Tab > Preview > Check the user is on this list.

Exchange 2003 View Global Address List

Exchange 2007/2010

On the Exchange Server > Start > All Programs > Microsoft Exchange Server > Exchange Management Console > Select Organisation Configuration > Mailbox > Address Lists Tab > Locate the all users Object > Double Click it > Select Preview > Check the user is on this list > OK > Cancel.

Exchange 2010 View Global Address List

Exchange 2013/2016

Connect to the Exchange admin center > organization > address lists > Default Global Address List > Edit > Preview recipients in the global address list includes… > Locate the user.

Exchange 2013 View Global Address List

The User/Mailbox IS listed on the Server But NOT in Outlook.

Remember, if you are looking at the Global Address List in Outlook then you are NOT looking at the Servers Global Address List*. If you are using Outlook 2003 or 2007 you may be in “Cached Mode”, and you are looking at a copy called the “Offline address book” This only gets updated Every 24 hours, and the copy on the server only gets updated every 24 hours at 04:00 (by default). In addition to this there a a few methods by which your Outlook clients get the offline address book.

*Note: Unless you are NOT in cached mode.

Outlook 2003 (and older)* clients get their OAB from a public folder, Outlook 2007 (and newer) clients can get their OAB from ‘Web-based distribution’ (basically form the website on the Exchange (or Exchange CAS) server. So there are three factors stopping you seeing that new user on the GAL (I personally advise you simply wait, however if that’s not an option, read on).

*Exchange Supported versions of Outlook

Support for Outlook 2000 was dropped with Exchange 2007, Exchange 2010 only supports Outlook 2003 (post SP2). Exchange 2013 only supports Outlook 2007 (post SP3 and cumulative update), and Outlook 2010 must be at SP1 with cumulative update.


a. Firstly force update the Offline Address Book.
b. Force your Outlook Client to Download the Offline Address book.
c. Check that the OAB is getting distributed from the Exchange/CAS server.

Update the Offline Address Book from the Global address List

Exchange 2000 / 2003

Click Start > All Programs > Microsoft Exchange > System Manager > Expand Recipients > Offline Address Lists > Right Click the “Default Offline Address Book” > Rebuild > HEED THE WARNING > OK > Right Click it again > Properties, You will see the time it updates (by default) you can change that here..

Exchange 2003 Update Global Address List

Exchange 2007 / 2010

1. On the Exchange Server > Start > All Programs > Microsoft Exchange Server 2007 > Exchange Management Console > Select Organisation Configuration > Mailbox > Offline address book tab > Right Click the Default Offline Address Book > Update > HEED THE WARNING > OK > Right Click Again > Properties > You can change the Schedule at which it updates.

Exchange 2010 Update Global Address List

Exchange 2013/2016

You can also force the OAB update with the following PowerShell command;

get-offlineaddressbook | update-offlineaddressbook

get-fflineaddressbook

Check the OAB is getting Distributed to Outlook

Exchange 2000 / 2003

Click Start > All Programs > Microsoft Exchange > System Manager > Expand the Exchange Organisation > Administrative groups > Administrative group name (First Administrative group is the default) > Expand Servers > Server-name > Storage Group (First Storage group will be the default) > Public Folder Database > Ensure it is mounted.

Then expand Folders > Public Folders > OFFLINE ADDRESS BOOK > Make sure it’s displayed as per the image below.

Exchange 2003 Public Folder Offline Address Book

Exchange 2007 / 2010

On the Exchange Server > Start > All Programs > Microsoft Exchange Server > Exchange Management Console > Select Organisation Configuration > Mailbox > Offline address book tab > Right Click the Default Offline Address Book > Properties > Distribution.

Note: Make sure the Generation Server is set to a server that exists, and it’s online.

In the diagram below you can see this server is performing public folder AND web based distribution, this is probably because you ticked this box when you installed the product.

Exchange 2010 OAB Distribution

For public folder distribution ensure the public folder database is mounted, and at least one server holds a replica. Also in the properties of the mailbox database, your users are using, make sure it points to the correct public folder database.

Exchange 2010 Public Folder OAB

For web-based distribution make sure the site is up.

Exchange 2010 Public Folder Web Site

Exchange 2013/2016

Exchange 2013/2016 will only be distributing the OAB via web-distribution. make sure the default website is up.

Exchange 2013 Public Folder Web Site

Force Outlook to Download the New Offline Address Book

For all versions of Outlook (since 2003) you have two choices, either take Outlook out of cached mode* (so it queries the ‘live’ global address list). Or force Outlook to download the latest version of the offline address book.

*Note: Disabling cached mode is not really a fix!
