I'm trying to set Alternate language(s) for some of our users' personal sites that are not fluent with the default language set (witch is French, and SharePoint doesn't seems to allow it to be changed).
I can explain the users how to do it manually, but I rather like do it myself for all concerned users at the same time.
I tried to adapt the code that I found there but I didn't manage to get the
UICulture or multilingual stuff working. There is no SPOWeb and the SPOSite does not seems to contain the required methods.
Any clues on the commandlet I could use?
