Office 365 Set mailbox default language
Posted On July 30, 2019
When you do large migrations, it might be convenient to change the default mailbox language settings for all your end users. By default each user needs to set the default language and time zone at first login to OWA in Office 365.
With the following PowerShell Script you should be able to change it within a few seconds. In this script we used the Dutch language code and Western European Standard time. Change it accordingly.
get-mailbox | Set-MailboxRegionalConfiguration -LocalizeDefaultFolderName: $true -DateFormat dd-MM-yy -Language 1043 -TimeZone "W. Europe Standard Time"
The Language ID is a number that corresponds to the correct language type. The following table shows you which number corresponds to which language.

Have you ever thought about including a little bit more than just your articles? I mean, what you say is valuable and everything. But just imagine if you added some great visuals or video clips to give your posts more, “pop”! Your content is excellent but with images and clips, this blog could definitely be one of the most beneficial in its niche. Excellent blog!
Hi,
I’ve thought about that, I’ve already created some video manuals, I might publish some in the future.
