Outlook – Teams Meeting – Change language of invite

Without meeting policy

By default, most users have the Office Display Language set to their native language.
When sending out a Teams meeting request in Outlook, you will notice this meeting request will use the Office Display Language.

Teams meeting request – Dutch

If you prefer the meeting request to be sent out in a different language, you’ll have to adjust your Office Display Language to the language you prefer for the meeting requests.

Outlook – Change Office display language

After changing the Office display language, restart Microsoft Outlook and restart Outlook.

Note: After restarting Outlook, you’ll notice the first Teams meeting invite you try to create will still be in the language that was previously set.
Just close this meeting request and create a new one.
This one should be in your new Office display language.

Teams meeting request – English

Using a policy to set default meeting request language

In an Organisation environment, it might be more interesting if this can be managed by the system administrators.

It is possible to pin the language used for the meeting invites down by using a Teams Policy.
The option which needs to be set is sadly enough not visible in the Teams Admin Center, so we’ll have to adjust this setting through Powershell.
For this we’ll need to use the MicrosoftTeams Module.

Below you’ll find the PowerShell commands which I used to add the Teams Meeting invite in 2 languages when you click on the Teams Meeting button in Outlook.

As this is a policy change, you will need to have a policy group to which you want to assign it.
I’ve created a new Meeting Policy (MattiasVdlTestGroup) just for testing functionality:

In case you haven’t installed the MicrosoftTeams module yet in PowerShell, execute the following code:

Install-Module -Name MicrosoftTeams -Scope CurrentUser

When you’ve got the module installed, connect to your tenant using the command:


A pop-up window will appear in which you will have to select the account which has Teams admin rights.

First I want to check to make sure the custom Meeting Policy I created can be found and what settings can be set for it.
For this I used the following command:


This gave me this result:

Next we want to the languages for the meeting requests.
In my case, I’ve set the language “en-GB” and “it-IT”.
This is done with the following code:

Set-CsTeamsMeetingPolicy -Identity "MattiasVdlTestGroup" -MeetingInviteLanguages "en-GB,it-IT"

Language codes can be found here:

Finally I wanted to assign this Meeting Policy to a custom security group I created in Azure Active Directory.
This is done in the Teams Admin Center:

The policy with the lowest number has the highest priority.

Display language in Hybrid environment

In a cloud environment, you can change your display language on Microsoft 365 (https://www.office.com) when you click on the gear icon on the top right of the page, and then selecting “Change your language”.

Office.com – Change your language

For users in a Hybrid environment, the possibility to chose the display language is greyed out.

Office.com – Change display language greyed out

In order to change the Display language, the user needs to contact the administrator of his organisation, which can then change the language to the preferred language in Active Directory.

The administrator needs to change the attribute “preferredLanguage” to the preferred language code under the users properties (Attribute Editor), in Active Directory Users and Computers.

Active Directory Users and Computers – User properties – Attribute Editor

After setting this value to the prefered value, it will take some time before this value is synced to Azure Active Directory, and take effect for the user in Office.com.

To speed up this proces, you can trigger a Delta sync from the server which contains the “Azure AD Connect” application.

Open a elevated Powershell Prompt on that machine, and type in the following code:

Start-ADSyncSyncCycle -PolicyType Delta
PowerShell – ADSync

Once the sync is completed, you should see the same value as you set under “preferedLanguage” in the properties of the user in Active Directory, appear in the Azure Active Directory admin center in “Overview” – “Properties”:

Azure Active Directory admin center – Preferred language

Next time the user in question logs in on Office.com, the language should be changed to the set value.
