How to fix error 805a8011 on Windows Phone.

I met 805a8011 today. It is one sneaky little error that made me scratch my head for quite some time.

This is a error that my Lumia 520 running Windows Phone 8 was throwing when Microsoft store was opened.

The symptoms that come with it are:

1. Internet works in IE on your Windows Phone and in some apps.
2. Microsoft store app won't even try to connect and throw this error.
3. WhatsApp won't connect to the internet.
4. Other possible symptom that I didn't encounter.


 This error is caused by LOW STORAGE space on your phone. You need to delete some photos, music or videos to make some space. Hopefully everything will be fine after you have about 100MB or more of free space on the phone.

The only explanation that comes to mind is that the OS needs this free space. Why? I have no clue.

When I Googled this, all I saw was few discussion of user having this problem and some of them 'fixing' it by a hard reset.

There was no official page from Microsoft explaining the meaning or reason for this error, let alone providing a solution. No one seemed to have an idea what this is. The discussions in languages other than English were also all dead ends. Even the clever Russians, to whom I turn to for solutions of such rare problems, had no clue.

I had this wild thought that the error was caused by the low storage space I had left. It struck me when I saw the measly 23 MB free space when I was browsing through the settings menu to find something relevant to the symptoms.

Good luck with your troubleshooting! Feel free to leave me a question or two.

Edit:

Here is another way to fix the error:

Try to manually synchronize your Microsoft account by going to "Settings".
Tap on "email+accounts".
Tap and hold on “Microsoft account“.
Tap on “Synchronize“.
