Hi,
After a month of this I got the following steps from Apple to fix this ugly thing.
First Run Disk Utility and run Disk First on your drive
Then take the following steps.
I had no access to anything relating to iCloud until I did this and now everything works again.
No more using Outlook for email!
To repair home permissions and ACLs:
1. Shut down the computer.
2. Locate the Command key and the R key on the keyboard. As you turn the computer on, press and hold Command-R before the gray screen appears but after you press the power button.
3. If you get a language screen, select your language and move forward.
4. You will now be in the OS X Utilities screen. At the top of the monitor select the Utilities menu.
5. Select Terminal
6. In the window that opens, type "resetpassword" (without the quotations, with no spaces and no capitals).
7. In the new window that comes up select the Macintosh HD at the top, then your user.
8. Click the button at the bottom right of that window to Reset Home Permissions and ACL's
9. When it is done, click the Apple menu () at the top left and select Restart
