That being said, can you help me understand a bit better what your rationale behind changing ownership was?
I have recently changed my Windows Live Id - that I use to access my Office Live workspace - to a new email address.I can log in my Office Live Workspace with the new Id, but I cannot access the stored files. Saving a new file will still show Modified by the old user ID.How can I have the Windows Id change reflected in Office Live?
Changing WLID is a known issue. We are working to solve this so you can make that switch without worrying about it.
I'm sorry this doesn't solve your problem today, but it is on our list.
