The language of your Outlook folder names will match the language of Outlook by default. But only the first time that you open your mailbox. To change the folder names in Outlook you will have to use the /resetfoldernames
switch.
Changing the language of your inbox folder items isn’t something that you do often. But when a user opens their mailbox for the first time in Outlook, the language matches that of the Outlook installation. So if that is English, then the folder names will be in English as well.
In this article, I will explain how you can change the folder names to another language.
Change Language folder names in Outlook
To change the language of the folder names we will need to restart Outlook with a specific switch. Make sure that you first have set Outlook in the correct language, because the folder names will match the language of the Outlook installation.
- Close Outlook
- Open the Start Menu
- Type:
outlook.exe /resetfoldernames
and press enter

Outlook will now open and the folder names should now match the language of your Outlook Installation.
Manually change the folder names in Outlook
We can also manually change the folder names in Outlook. This way you can translate the folders to any language that you want, without the need to change the language of Outlook.
To change the names, we are going to use a small program, MFCMAPI.
- Download MFAMAPI.X64.exe from this Github page. Choose the third option: MFCMAPI.x64.exe.21.0.21127.03.zip
- Unpack the zip file and open MFCMapi.exe
- Click on Session > Logon…

- Click Ok to open your Outlook profile
- Double-Click on your mailbox
- Expand Root – Mailbox
- Expand IPM_SUBTREE

8. Click and wait a second on a folder name to change the name of the folder

When done close MFCMAPI and start Outlook.
Wrapping Up
The easiest way to change the folder names in Outlook is to first set the correct language in Outlook and then use the outlook resetfoldernames command. Manually changing the folder names is an option, but can be a bit time-consuming.
