Assuming the HiddenFromAddressListsEnabled attribute is set to $False on the mailbox or distribution group.

When an entry is missing in the Global Address List it is not necessarily needed but good to know if we can find the object in the GAL on the server.

If an entry is missing in the Global Address List you can query the GAL on the server:

Independently from the outcome of the above PowerShell commands I usually update the Offline Address Book and the Global Address List afterward.

I have put in the option to query the Global Address List for the missing entry because I usually do it.

Ok here we go > Update the Offline Address Book:

Now update the Global Address List:

In most cases, this solves it.
 
I usually wait 15 Minutes [ one AD sync cycle ] before notifying the customer.
The user should download the Address Book afterward or restart Outlook.
In OWA new entries should be visible straight away.
 

If the problem persists check the showInAddressBook attribute on the object in AD:

Compare the values of the attribute showInAddressBook with an account or DL that is available in the Global Address List and add them accordingly if one or more entries are missing.

If appropriate entries are missing here you wouldn’t get a result when querying the GAL for the missing entry at the beginning of this post. Further it is likely that HiddenFromAddressListsEnabled is set to $true.

When HiddenFromAddressListsEnabled is set to $true:

Find some examples at the end of this Microsoft description.
 
If all entries are visible in showInAddressBook you should be fine.
Otherwise add the missing entries under showInAddressBook.

 
Have a nice day!

Part 3: Join AD Domain Server Core

This is Part 3 of how to Prepare a Hyper-V Exchange 2019 Lab and this post named Join AD Domain Server Core describes exactly what the name suggests:  We will join Windows Server 2019 Core ( Exchange2019 ) to the Domain we have set up in Part 2

Join AD Domain Server Core – Join Server 2019 Core to AD domain:

Logon to Exchange2019 ( Windows Server 2019 Core ) and type:

> sconfig > Choose 1  > Choose (D)omain
> type in the name of the domain to join. In this case testlab.local.

You will need to provide the credentials of the domain admin user.

When asked if you want to rename the computer before restart do so if not already done otherwise click:

Your domain ( testlab.local ) should be pingable now from this server.

Manage Server Core from AD Server Manager via GUI:

Log on to AD2019 ( Windows Server 2019 Desktop Experience ) and open Server Manager
Go to:

> Dashboard > Add other servers to manage

Choose the DNS tab and write in the server name of the Exchange 2019 server ( Exchange2019 ):

> Add the server and click OK.

Exchange2019 will now appear in All Server ready to be managed with the following options to your disposal:

Before we start to install Exchange Server 2019 on Windows Server 2019 Core ( Exchange 2019 ) let’s check the system requirements and prerequisites covered in Part 4:

Part 2: Install Active Directory Role Server 2019

In order to install Exchange 2019 on Windows Server 2019 core, we will need an Active Directory Server promoted to a Domain Controller. In Part 1 we already have prepared 2 VMs running Windows Server 2019 Desktop Experience ( AD2019 ) and Windows Server 2019 Core ( Exchange2019 ).

Install Active Directory Role on Server 2019 ( Desktop Experience )

Log in to the AD server and get rid of the nasty stuff + some preparation:

Configure a static IP address and Default Gateway on the NIC of the default switch:

The Default Gateway and preferred DNS IPs point to the HyperVisor default IP 172.24.96.129 which NATs to the NIC of the host machine.

>OK

After login with the built-in administrator account, I was not able to open the  network adapter options via right click on the taskbar > Open Network & Internet settings >  Ethernet > Change adapter Options:

It was possible though to open the network adapter properties the old school way:

You can find some workarounds on this TechNet forum:
Network-change-adapter-options-windows-cannot-access-the-specified-device-path-or-file

I worked around this issue creating a new domain admin user by copying the built-in administrator:

After login with the new admin, the adapter options can be opened via the network icon in the taskbar.

In Part 3 we will join the 2nd VM running Windows Server 2019 Core to the domain:

We won’t be able to deliver this message because the email address is no longer valid.

Additionally calendar delegates are not able to access the calendar of the person whose mail address displays the mailtip after it has been chosen from the GAL.

The Global Address List obtains the recipient’s address from the following fields which represent all the same attribute :

The value of the mentioned fields should be the same as the PrimarySMTPAddress or should at least contain an alias address from emailaddresses.  Otherwise the email address no longer valid message will be displayed as mailtip.

If you have just a few affected recipients it is easier to just paste the PrimarySMTPAddress into the E-mail field under the general tab of user properties.

When this issue occurs with more recipients you may want to change it in bulk by setting the WindowsEmailAddress to the same value as the PrimarySMTPAddress.
In our case this problem occurred when a customer initially synchronized an OU via our Microsoft Identity Management server. Later he changed the PrimarySMTPAddress for all his mailboxes on our platform but left the initial synchronized E-mail address in the source AD.
So the initial address got synchronized again overwriting the changes.

Hope it helps when an email address no longer valid message starts to get on your user’s nerves.

Enjoy the summer
