Steps to change the language and regional settings on Exchange server
One of the reason to change the language
For Instance: Your source Inbox folder is named 'Boîte de réception', which is in French language. If you migrate this folder directly to the destination server then by default it will not get mapped to the 'Inbox' folder on target server. In order to map this to the respective folder, change the regional settings on exchange target server to that of your source mailbox folder language (in this case, it is French).
Steps to change the language settings:
1. Sign in to Outlook Web Access.
2. Click on the Options button on the top right of your screen, then select See All Options.
3. In the navigation tree on the left, click on Settings.
4. Click on the Regional tab.
5. From the Language drop-down menu, select the language.
6. Check the option Rename default folders so their names match the specified language.
7. Click the "Save" button.
8. Your default system folders should now be renamed to the selected regional language.
