I Get "Error 4201. Client. Folder name is disallowed" with Hotmail!
Q: I have the latest Hotmail Connector installed, but when I
try to sync my mail it tells me "There is an
error synchronizing your mail account. Please verify your account is
configured correctly by first accessing your mail on the web. Error:
4201. Client. Folder name is disallowed." What do I do?
A: Most likely you have created a custom folder that has an illegal name. Hotmail can be touchy about folder names sometimes. Names that work fine on the Outlook side won't sync to the server side. If you have any custom folders, especially ones with longer/more complex names you might try renaming them to something shorter/simpler and see if that helps.
