Outlook Office365 Work Account Error 0xCAA70007

Outlook 365 0xCAA70007 error message connecting to onmicrosoft Office365 account: You'll need the internet for this 0xCAA70007

Hi,

I'm facing an issue with accessing my onmicrosoft Office365 account with outlook. Whenever I open outlook in windows it shows the prompt "You''ll need the internet for this". The message says we couldn't connect to one of the services we need you sign you in. Please check your connection and try again.

The error code is - 0xCAA70007

The outlook works fine in the browser and internet connection is working.

I tried repairing office and also removed outlook credentials.  I have also uninstalled office and now the client will not even load.  

How-I-fixed-it:

I found the solution to my problem in Microsofts answers:

This is what I did:

• Shut down all Office Apps
• In Explorer, navigate to  C:\Users\%Username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC\Microsoft\Crypto\TokenBindingKeys\Keys
• Delete the Keys in the folder
• Relaunch Outlook - Keys are re-created automatically.

Office 365, Outlook 2013: OpenXChange OXTender 2 MAPI Mail profile error "oxstor.dll" could not be loaded

Today i installed Office 365 in parallel to my existing Office 2010 on my Windows 8 Computer. Under Outlook 2010 i use OpenXChange OXTender 2 - Version 7.0.62 to sync with OpenXChange Groupware.
After installing Outlook i created a new mail profile. But in Outlook 2013 i can't open the MAPI Folder. Clicking on it an error message Pops up "The Folder could not be expanded.... MAPI was unable to load the Information service "oxstor.dll" ..."

I also re-installed OXTender, but this did not fix it. Under Outlook 2010 the sync is still working fine.

I posted the question here:

How-i-fixed-it:
The document Outlook OXtender 2 Best Practices states, that it does not work having both Office 2013 and 2013 installed in parallel:
...
Please note that the following is not supported:

• Office 2010 Home and Business test version
• MS Outlook running in a virtual environment (e.g. VMware or Parallels Desktop)
• Using both OL2007 and OL2013
• Using both OL2010 and OL2013

....

I removed Office 2010 from my Computer and re-installed Outlook OXTender again, created a new profile and... it works.
