I've just signed up to Office 365 (Home) and a OneDrive account. I'm trying to share a folder of documents so that another user can edit anything in that folder.
Although when I started I seem to have managed to share a couple of test files as read-only, every time I try now I get a message that sharing is temporarily blocked. To unblock, it wants my mobile number to send an authorisation text.
I don't want to give my mobile number to Microsoft! Is there another way to unblock this?
