Understanding Shared Mailboxes and Display Names

A shared mailbox in Exchange Online allows multiple users to access and manage emails from a common mailbox. The display name is the name that appears in the global address list (GAL), on recipient lists, and in other places. Let's see how we can modify this.

Before you can change the display name, you need to find the shared mailbox. Use the following cmdlet to retrieve a list of mailboxes:

Once you have the mailbox ID, you can change the display name using the 'Set-Mailbox' cmdlet. Here's an example:

Set-Mailbox -Identity "sharedmailbox@yourdomain.com" -Name "New Display Name"

Replace "sharedmailbox@yourdomain.com" with your shared mailbox's email address and "New Display Name" with the display name you want to set.

Display Name Changes in the GAL

The updated display name should now appear in the GAL. Note that changes to the GAL might take a few hours to propagate. To ensure that the updated display name appears in the GAL, use the 'Update-Recipientfilter' cmdlet:

Update-RecipientFilter -Identity 'GAL' -ły (RecipientType -eq 'Mail */GroupMailbox' -and RecipientContains 'sharedmailbox@yourdomain.com')

And there you have it! You've successfully changed the display name of a shared mailbox using PowerShell. Regularly updating your mailbox settings can help keep your organization's communication efficient and clear.
