How to Set Outlook Folder Language for Different Microsoft 365 Users
Question details
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.

- 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.
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.
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.
Open the Windows Control Panel, change the view to Large Icons, and click on 'Mail (Microsoft Outlook)'.
Click the 'Show Profiles' button, then click 'Add'. Name the new profile according to the user or region and click OK.
Follow the on-screen prompts to add the Microsoft 365 email account to this new profile and finish the setup process.
Open Outlook with the new profile, navigate to File > Options > Language, and set the Office display language to the user's preferred regional language.

Adjust Interface Language in Outlook on the Web
Modify the display language directly through the Outlook web interface to instantly change regional settings and optionally rename default folders.

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.
