Understanding the Display Name in Exchange Online

The display name in a shared mailbox is the name that Exchange users see when they view the shared mailbox in their global address list or when they send a message to or receive a message from the shared mailbox. Changing the display name can help make the mailbox more easily identifiable.

The display name you set is also used as the 'From' name when sending messages from the shared mailbox. This can be particularly useful in customer-facing situations where you want to control the representation of your organization to external parties.

Accessing the Exchange Admin Center

Before you start, ensure you have the appropriate permissions in your Exchange admin center (EAC). You'll need to be an administrator or have the Exchange administrator role. To access the EAC, sign in to your Exchange Online portal using your admin credentials.

Once you've logged in, you'll be presented with a dashboard containing various settings. Familiarizing yourself with this interface will be crucial in managing your Exchange Online environment effectively.

Reverting or Additional Changes

If you want to revert the changes or make further modifications, simply repeat the process. However, do so with caution to prevent any disruption to existing workflows or communications.

Remember, the display name change will only apply to the shared mailbox itself. If users have existing email addresses that were sent to the old display name, these will still function until manually updated.

Lastly, ensuring consistency in your display names can significantly enhance user experience and credibility. Consider setting up a policy or guide for managing shared mailbox display names to maintain this consistency.
