I have been in contact with the OneDrive support, but they seemed unable
to help much.
However, I did eventually manage to log into OneDrive.app. Suport asked
me to clarify a number of points:
_______________________________________________
• Make sure you are using the correct account to login to the OneDrive
app.
•Try it once more for us if you wouldn't mind and let us know if it
worked or if the error message has changed.
• Note, that you can only use 1 Personal OneDrive account on the device
at a time.
• Check if issue persists on a different connection (e.g. 4G / Wifi).
•If you are able to sign-in with same credentials in web browser at
https://onedrive.live.com
• Check if issue affects another Microsoft account.

I did some expermentation and replied:
_______________________________________________
* I have only one Microsoft account.
* I have tried it again with mixed results.
1. I clicked on the
OneDrive.live.com link and to my utter astonishment
OneDrive.app opened and loaded my folders, with no need to enter name or
password. I left it to upload my photos, which it did.
2. I then signed out and attempted to sign in again - exactly the same
problem as before.
3. I went back to your email and clicked on the link; this took me to
OneDrive.app and the blank loading screen. After waiting several minutes
I double-clicked my home button and stopped OneDrive.app.
4. I returned to Mail and clicked the link again. OneDrive.app opened
and this time let me sign in successfully.
* As noted above, I have only one Microsoft account.
* My iPad connects to the internet via Wifi only. There is no
alternative.
* I can sign into Skype and Outlook.app with no problem. I do not
normally use either on my iPad.
* I can sign into the OneDrive web site on my iMac, and on the iPad if
OneDrive.app is not installed.
* As noted above, I have only one Microsoft account.
One additional point: when I deliberately enter an incorrect password,
OneDrive.app detects and rejects it at once. The problem only arises
when the correct username and password are used. The bug must trigger
after the password is accepted as correct.

So you might try going to
https://onedrive.live.com in Safari and
letting it launch OneDrive.app (which it should do), and trying to log
in then.
I have not attempted to tinker further.
Oh, and don't forget to put out a saucer of milk for the little people
first!
