The OneNote issue
Since I installed Windows 8.1 I can't open my OneNote notebooks stored on SkyDrive with OneNote 2013.
When I try to open a notebook in OneNote, I get the following error:
We can't get your notebooks right now. Please try again later.
I can open them without trouble in the Modern UI OneNote app, but I can't open password protected pages there.
Also if I try to open a notebook from a browser, I get the following error:
We couldn't open that location. It might not exist or you might not have permission to open it.
I also cannot create new notebooks on SkyDrive:
The specified location is not available. You do not have permissions to modify the specified location.
Can it be fixed somehow? Or can I at least save a notebook to my hard drive without opening it in Office? The backup file got deleted with the Windows 8.1 installation.
Edit: I tried reinstalling Office and unlinking then relinking my Microsoft account, but no luck. I also tried OneNote with my other Microsoft account which I don't use and it worked perfectly - OneNote could open notebooks from that account's SkyDrive and I could read those without problem. When I switch back to my Microsoft account which I use with Windows 8.1, however, the problem is still there.
What can the problem be with this account?
Also, I noticed that the working account saves new notebooks to
https://d.docs.live.net/----/Documents/, whereas the broken account wants to save to
https://d.docs.live.net/----/^.Documents/. Why are the
^. characters present? Is it possible that the problem is caused by this invalid path name?
The Office sign in issue
So I think these two problems are related.
Not only does OneNote not work, but neither do any of the other Office programs. My Office Upload Center is filled with a bunch of Word, Excel and PowerPoint files with the status "Upload failed, Sign in required". I can click on "Resolve" → "Sign in", which causes the status to change to "Upload Pending", but then it goes back to "Upload Failed, Sign in required".
I can also click on "Open to Resolve", which opens the document in the respective Office program and asks me to sign in. If I click that button, I get a message saying "Document not saved".
