I read a forum question this week, where the user asked if it was possible to change his base language from French to English and he was a CRM 2011 online user.
It was quickly explained to the user that it’s impossible to change the base language.
This is a commonly known fact for experienced CRM users and might even be one of the questions on one of the CRM exams.
Suddenly from out of no where a CRM Support engineers flies in with this answer
It is correct that in the past changing the Base Language was not possible. I must inform you though that it can be achieved now by opening a Support Ticket with the Technical Support team. The base language change has it’s cost though, it can only be achieved by de-provisioning/re-provisioning your organization (deleting/recreating) which means that any data or customizations you have on the organization will be lost during this process. You will need to take care of backing up the data yourself if that is needed.

So now it seems if you are willing to give Microsoft some cold hard cash they can change the base language but it will remove all your data and customizations will be lost. This sounds suspiciously like they are just creating a new blank CRM to me and getting paid for it. This is a rather drastic measure which I can’t really see anyone going for but file it away in the good to know (but not that useful) draw.
