As far as I have found out the language setting in Office is either connected to all documents the user can made (the default setting) or to a specific character in a document (or document if you selects all and then set the language). This is made for a user using only one language, but for many user that use two or more languages this can be frustrating.

This is manageable in Word, but in PowerPoint it becomes a problem when I switch between two languages from presentation to presentation. When I insert a new slide the language is often not what I wanted and I have to manually set the language for the text boxes on the slide. I have made a template where all slides are in my desired language, but nevertheless, I get wrong language setting when I insert a new slide. I have also tried to set the default language when I start with a new presentation, but it seems having no effect when inserting new slides. It is not possible to set the default language without having an active presentation. I think that would be natural.

Could anyone give me a workaround? Or can the PowerPoint-team/Microsoft make it possible to connect the language setting to a template? Thanks.

Hello, you might want a language pack?
I work in French and English with PowerPoint and it works perfectly for me without having to set manually the language.

Hope this help,

Thanks, but I'm afraid that's not helping me. First, I use Office Mac 2011, then as I understand it, language packs helps for spelling and menus. I prefer using the English version of Office, but make presentations both in English and Norwegian.
