How to Change Your Name in Microsoft Teams Meetings in 2026: 3 Name Types and Permission Limits Explained

Why Does Your Name Still Show the Old One in Meetings After You Change It?

Last week, I had a meeting with an external vendor. The name on the invitation was "Wang Xiaoming," but when they entered the meeting, it showed "wang_xm_2023"—I was genuinely confused for a moment and didn't know how to address them.

Later, I realized that many people searching for "how to change your name in Teams meetings" are actually stuck on a fundamental misunderstanding: There are at least 3 different "names" in Teams, and they're changed in completely different places.

In this article, I'll share the pitfalls I've encountered and clearly organize how to change all 3 name types, so you don't end up changing things for a while only to still see the old name in meetings.

First, Clarify: Which Name Do You Want to Change?

Under the Teams architecture, there are 3 main names related to "names":

1. The meeting title itself: The name that appears on your calendar and meeting invitations.
2. Your own display name: The name others see in meetings.
3. Guest display name: The name shown for external invitees when they join the meeting.

These 3 names have different modification entry points, effective times, and permission restrictions. Let's go through them one by one.

Type 1: Changing the Meeting Title

If You're the Meeting Organizer

The most common scenario: You created a meeting with a casual title and later want to change it to a formal one.

Here's how:

1. Open the "Calendar" in Teams.
2. Click on the meeting you want to modify.
3. Click "Edit" in the top-right corner.
4. Modify the meeting title field directly.
5. Click "Send Update" to send the change to all participants.

This change will sync to all invitees' calendar invitations. However, note that for meetings already in progress, the title won't update in real-time—participants may still see the original meeting name on their screens.

If You're a Participant, Not the Organizer

From my experience: You can't directly modify a meeting title created by someone else.

If you're just an invitee and see a typo or a vague meeting name, the best you can do is ask the organizer to change it. Teams doesn't grant general participants permission to edit meeting invitations.

Type 2: Changing Your Own Display Name

This is what most people actually want to change. The name shown in meetings is tied to your Microsoft account.

Regular Members Can Do This

1. Open Teams and click your avatar in the top-right corner.
2. Click your name to go to your profile.
3. Click "Edit Profile."
4. Modify the display name and save.

After changing it, new meetings you join will show the new name. However, if you're already in a meeting, some versions may require you to rejoin for the change to take effect.

When Admins Are Involved, It Gets More Complex

According to admin responses on Microsoft Q&A, if your account is managed by your company's IT department, changing your Teams display name may also affect your Office 365 email display name.

This means if you want to change your Chinese name to an English one for easier recognition by international colleagues, you might find that your sender name in emails changes too.

So, if you're operating under a managed corporate account, it's wise to check with IT before making changes:

• Does the company have a unified naming convention?
• Will this change affect the email display name?
• How long will it take to take effect?

Microsoft's official documentation also notes that some name changes may take up to 24 hours to fully sync across all services.

Type 3: Changing Guest Display Names

When external guests join meetings, their names often appear as "abc," "guest_123," or system default accounts, which is confusing for meeting records and addressing them.

Guests Can Change It Themselves

Before joining a meeting, Teams usually shows a screen where guests can enter a name. Simply change the display name to a proper name in Chinese or English before joining.

However, many people habitually click "Join Now" and skip this step, resulting in the default account name showing in the meeting.

Organizers Can Remind, But Can't Directly Change

As the meeting organizer, you cannot directly modify a guest's display name during the meeting. What you can do is:

• Before the meeting, remind guests in the invitation to set their names properly.
• At the start of the meeting, verbally remind everyone to check their display names.
• If someone's name is too vague, ask them to leave and rejoin, modifying it before joining.

Admin-Level Changes

For internal guest accounts, admins can modify display names in Azure AD. But keep in mind:

• Changes may not reflect immediately in Teams.
• It may take up to 24 hours.
• This change may also affect display names in other Microsoft services.

3 Things to Know Before Changing Names

1. Changing Display Name Doesn't Change Account Name

Updating your display name in the Teams app doesn't change your Microsoft account name itself. This is good for those who want to distinguish between "internal alias" and "official account."

2. Real-Time Text Makes Names More Important

Microsoft's roadmap shows that Teams launched Real-Time Text (RTT) in May 2025, allowing participants to communicate via text in real time during meetings.

This means display names have become more important—if everyone's names are vague, it becomes hard to track who sent which text message. My recommendation: For internal meetings, require members to use a "Department + Name" format; for external meetings, at least use "Company + Name."

3. Meeting Names and Meeting Content Are Two Different Things

Changing the meeting title or display name doesn't change the fact that the meeting still needs to happen and content needs to be recorded.

My own approach: When hosting Teams meetings, I use Tinrec desktop to capture system audio directly, without adding extra bots to the meeting. After the meeting, transcripts, summaries, and action items are automatically organized, so I don't have to spend time re-listening to recordings or manually writing meeting notes.

Getting names right is important, but preserving meeting content is equally crucial—that's what complete meeting management looks like.

Summary

Teams has 3 types of "names": meeting titles, personal display names, and guest display names, each with different modification entry points and permissions.

The most common need is changing your personal display name, which regular members can do in their profile; but be cautious with managed corporate accounts, as changes may affect email display names and take up to 24 hours to fully take effect.

Meeting titles can only be changed by the organizer, while guest names require guests to modify them before joining.

Once names are set, recording meeting content and organizing it into action items and minutes ensures no meeting just disappears after it ends.
