UC Unleashed

Anyone who’s had a new mailbox on Exchange 2007 and logged in via OWA will remember seeing a screen that asks for the language and time zone, as seen below. Once they pick those, they are then taken to their mailbox.

If all of the users in an org use the same language and are in the same time zone, we can set these settings. New users will no longer be prompted for this information, but any user can change the information by going to to Options>Regional Settings in OWA, such as shown below:

To make the change, fire up the ol’ Exchange Management Shell and type:

Set-OWAVirtualDirectory "owa (Default Web Site)" -DefaultClientLanguage <Locale ID>

Replace <Local ID> with the specific Local ID for your area. For a list of Local IDs, see Locale IDs Assigned by Microsoft. For English in the United States, the Local ID is 1033. So, for my example, I use

Set-OWAVirtualDirectory "owa (Default Web Site)" -DefaultClientLanguage 1033

Once that’s set, all new users will default to that, as well as the time zone setting on the client access server.
