Using Outlook for iOS in business environments for email and scheduling
Mine was acting the same way; intermittent syncing issues and prompt's for password. But I don't know my status. I removed my Outlook through the Apple mail account about 3 days ago. That's the account that had the problem and I did not want to see the password requests. I'm using the Outlook App account from the app store (which I suggest everyone with the problem tries) which is working perfectly. My guess is that this account is going through a different server which does not have the issue. This problem has to be much more wide spread than it appears here. It's just not being reported in this forum.
