Change regional Settings for a Mailbox using powershell

Below is the screenshot of a regional settings page from the OWA, these settings can now also be set using the PowerShell, which I am going to discuss in this post.


I came across this issue where the mailbox folder names were showing in regional language, and I was requested to change them into the English language, in this post I will demonstrate the steps I took to make the changes.

Get the current regional settings# Run the below CMD to get the current regional settings

Get-MailboxRegionalConfiguration -Identity sunil

Set the new regional Settings# Run the below CMD to change the regional settings

Below example sets mailbox language to English US and localizes the default folder names in English.

Set-MailboxRegionalConfiguration -Identity sunil -Language en-us -LocalizeDefaultFolderName

This example sets the date format for Sunil's mailbox.

Set-MailboxRegionalConfiguration -Identity Sunil -DateFormat "d/m/yyyy"

Below Culture Name can be used for setting Language.
