How to change the display sender name in Outlook: Desktop and cloud version walkthroughs

Display names provide users with the opportunity to present additional information, conceal their identity or promote their organization. This is achieved via a special name used in place of your actual name and will be present across the Office 365 suite.


  1. Open the Office 365 Admin Center
  2. Open the Users dropdown
  3. Select Active users
  4. Select a user by clicking their name
  5. Scroll to the bottom of the user card
  6. Select Manage contact information
  7. Input a display name in the labelled box
  8. Click Save changes

Please note that the method above will change the user’s display name in all Microsoft 365 applications — not just Outlook.

In this post, we will be helping you learn all about display names in Office 365 — what they are, where they are, how to get them, and how soon the change will be reflected. If you need help, stick around for our image-guided step-by-step walkthrough.

What you need to know about display names

What is a display name

A display name serves as the name presented to viewers of content posted by you, as well as the name presented to viewers of your account. This is particularly useful for work accounts where your name would otherwise be in use.

Where will people see my display name

Display name’s are associated with your account and thus appear wherever your account is viewed. This means your display name will not only appear within Outlook but other applications as well

Will my display name appear straight away?

Unfortunately no. When preparing the demo for this post we found that a change in display name (even if it’s your first one) can take several hours to take effect.

Setting an Office 365 display name for Outlook via the Microsoft 365 admin center

Please note that a change in the display name could take some time to update. Try checking your name in Outlook the following day. We found this out when creating the demo that we’re going to walk through now.

Step 1 – Access the Office 365 Admin Center

To begin, visit to access the Office 365 Admin Center. we’ll need to access the admin center to update user display names. Be sure to use an account with Administrative privileges.

If you don’t have an account with admin privileges, the link above won’t work for you. Speak to your organization’s Microsoft 365 admin about getting the privileges, or send this blog post over to them and they can make the display name changes for you!

Step 2 – Open the Active users page

From the Admin center, locate the side panel on the left. Click Users to reveal its additional options. Select Active users.

Step 3 – Locate the user and click their name

Once you’re on the Active users page, locate the user you wish to change the display name for.

Please note that there is no easy way to change display names in bulk. You have to do this one user at a time.

Step 4 – Open the contact details menu

Scroll to the bottom of the user account card. You’ll be able to identify the Manage contact information option under the Phone number header.

Step 5 – Input your intended display name

Look to the textbox labeled Display name. The display name in the demo has been hidden for privacy purposes. Upon entering a display name, select Save Changes to finish.

Step 6 – Send an email to test your display name

If you’ve only just updated your display name, we recommend waiting several hours before attempting the following step. However, if you’ve already finished waiting send an email and head to your Sent folder in Outlook. From there we can view your email and check the name displayed.

End note


A display name within Office can be applied (albeit with some delay) via the Office 365 Admin center. Although a change will not take effect immediately, the change is useful for promoting your organization or somewhat concealing your name.
