Users in different regions need to view Microsoft 365 mailbox folders in their native language without changing the folder names for other users accessing the same mailbox.

How to Set Outlook Folder Language for Different Microsoft 365 Users
Product
Microsoft Outlook
Device & OS
not provided
Scenario
Configuring display and folder languages for shared mailboxes or multiple users accessing a central Microsoft 365 account from different international regions.
Observed behavior
When one user changes the folder language settings, the default folder names (like Inbox or Sent Items) change on the server, disrupting the experience for users who require a different language.
Before you start

Verify whether users are accessing a shared mailbox or logging into the primary account, as language modifications at the server level will automatically sync and alter the folder names for all connected clients.

Solution 1Recommended

Configure Separate Outlook Profiles for Different Regional Users

Creating individualized Outlook profiles prevents local client language settings from conflicting with the central mailbox configuration used by other team members.

Because default folder names are tied to the mailbox language on the Exchange server, simply changing the language on one machine can affect everyone. By managing separate Windows profiles and Outlook profiles, you can maintain localized UI languages.

1
Open Mail Setup

Open the Windows Control Panel, change the view to Large Icons, and click on 'Mail (Microsoft Outlook)'.

2
Add a New Profile

Click the 'Show Profiles' button, then click 'Add'. Name the new profile according to the user or region and click OK.

3
Configure the Account

Follow the on-screen prompts to add the Microsoft 365 email account to this new profile and finish the setup process.

4
Set Display Language

Open Outlook with the new profile, navigate to File > Options > Language, and set the Office display language to the user's preferred regional language.

Configure Separate Outlook Profiles for Different Regional Users
Avoid Resetting Folder Names Globally: Do not run the 'outlook.exe /resetfoldernames' command from the desktop client unless you want to force the server's folder names to match this specific user's language, as it will impact all other users.

Frequently Asked Questions

Why do my Outlook folder names change when a colleague changes their language?

Default folder names (like Inbox, Sent Items, and Deleted Items) are stored at the mailbox level on the Exchange server. When a user updates their language settings and chooses to rename default folders, that server-level change syncs to everyone accessing that specific mailbox.

Can a shared mailbox have different folder languages for different users simultaneously?

Natively, Exchange shared mailboxes enforce a single language for the default server-side folders. While users can have their own Outlook client interface (menus, ribbons) in their native language, the actual folder names will remain in the language established on the server.

Does changing the Outlook desktop display language automatically rename my folders?

No. Changing the Office display language under File > Options > Language only changes the user interface menus and buttons. It does not rename the default folders on the server unless you specifically launch Outlook using the '/resetfoldernames' command switch.
