Unable to sync outlook email on Windows Phone (error 86000C0A) or Windows 8.1 Mail app ("not available")

Exactly the same almost 14 days: 2 Live accounts, each sync error 86000C0A on Lumia 920, each service isn't available in Windows 8.1 "touch" Email application. These errors appear many times per day. Live accounts connected via Outlook Connector (Outlook 2007) seem to work correctly.

What's even worse, these apps (Windows Phone, Mail app) do sync every now and then. For example, I've been out of town for 2 weeks and the Mail app on my PC says it last synced 17 days ago, even though there are fresh emails in there, from today. :S So it works... Sometimes. But I cannot send emails using Mail on my PC.

What a mess! :S

Following a suggestion by someone somewhere to deactivate SMS and chat backup on the phone I did just that and the error is now gone. :) And even Mail apps on my Windows 8.1 devices began syncing normally. Try deactivating SMS backup and leave it be for a while (for me it didn't do trick immediately, but I was to **SG#FDG off by everything I set the phone aside and forgot about it, and when I checked it later everything was fine).

Did not work for me. Another thread recommended adding your mail address again as a separate non-linked box.  This has worked - it seemes to use your provider's servers rather than hotmail

Currently the best cure is to disable SMS and Chat backup, as it seems. I can vouch for it being 95% effective, only sometimes Windows 8.1 Mail app starts acting again but for a short while only. And more and more people are contacting me lately with the same problem, it's amazing how this is spreading like a disease. :S

It worked for me:

1) Soft reset the phone: press and hold Volume Down + Power button during 12 seconds

2) Open Internet Explorer (from phone) > go to http://account.live.com > sign in with the microsoft account we cannot sync on the phone.

3) Come back to the start screen

4) Go to settings > email and account > press and hold the account > tap on sync

or Go to settings > email and account > add an account > microsoft account

I had a similar issue 800c0008 error with outlook on windows phone 8.1 refusing to sync and OneDrive not working. I used the browser to access outlook or told me a problem had occurred but still allowed me t check mail. Then it told me that some conditions had changed (didn't let me read them) and I pressed the continue buttons expecting some t&cs to appear. It just took M to my inbox. Since clicking continue, outlook mail syncs fine on the phone.

All I can surmise is that outlook will not sync until it has told you that some t&cs have changed and you have pressed the continue button.
