Reset mailbox foldernames Exchange 2010
Sometimes when you import pst’s into exchange 2010 you got some problems with language settings and foldernames. I discovered that the option / Resetfoldernames didn’t work. So I had to look for another solution.
On the exchange 2010 server you can run the following command
| Set-MailboxRegionalConfiguration –Identity **alias** -dateformat "d-M-yyyy" -timezone "W. Europe Standard Time" -timeformat "HH:mm" -Language "nl-NL" -LocalizeDefaultFolderName:$true |
After running this command all your mailboxfolders wil show up in the language you specified.
If you want to do this for all the mailboxes in the organization. You can run
| Get-mailbox | Set-MailboxRegionalConfiguration -dateformat "d-M-yyyy" -timezone "W. Europe Standard Time" -timeformat "HH:mm" -Language "nl-NL" -LocalizeDefaultFolderName:$true |
