Recently I have had a few scenarios, where we had to change the Language and Time Zone of all or certain specific user Mailboxes in Office 365. So I thought, I might as well write up, this blog post, to collect all the information needed, to change setting on Language and Time Zone on Mailboxes.
This would also work for Exchange (on-premise), it is the same cmdlets.
If you need to do this, you need to connect to Exchange Online using PowerShell and use the following cmdlet: Set-MailboxRegionalConfiguration
Once connected to Office 365 using Powershell, you can change settings by running the cmdlet:
Get-Mailbox | Set-MailboxRegionalConfiguration -Language -TimeZone
For Language, there is a Language ID to use and for Time Zone, you have to specify the Time Zone name. I have found all Language and Time Zone options, which can be used and they are documented below:
Language ID option
The Language ID is a number that corresponds to the correct language type and the table below, gives you a good overview of which number corresponds to which language:

Examples
In the Example below, I will set my mailbox in my Office 365 Tenant to the Danish Language (DK) and the GMT+1 Time Zone (Romance Standard Time).
Get-mailbox [email protected] | Set-MailboxRegionalConfiguration -Language 1030 -TimeZone "Romance Standard Time"
Below, I will now be doing the same for all Mailboxes in my tenant, which would be the following command:
Get-mailbox | Set-MailboxRegionalConfiguration -Language 1030 -TimeZone "Romance Standard Time"

This was very helpful but I had to change “A.U.S. Central Standard Time” to “AUS Central Standard Time”. Something else I found handy was -EA “SilentlyContinue” to continue on error.
