Sorry for my bad English!
I read the writings from PDiddy825.
I also do not have a Click-To-Run version of Outlook. I have the full Home and Business version of Outlook.
As he recommended I went to the Control Panel, searched for the Microsoft Outlook, I clicked on it, above, I clicked on Repair and it took about 10 minutes to run.
Then, finished repairing, I was asked to reinitiate and so I did.
After the reboot, I opened the ICloud Control Panel that stays activated in windows bar and it opened well and the problem was fixed! The Mail, Contacts and Calendar were active again!
The ICloudPanel asked me if I wanted to synchronize (as it was the first time), I asked YES, and it made contact with my ICloud account and synchronize my Calendar (I choose not to synchronize the Contacts, because since the problem began I started saving my new Contacts on ICloud website).
After that, I opened the Outlook and all of my compromises in Calendar were save on Outlook. Then I made a synchronization with my IPhone 4 and it worked very well. Only a few “dates” were duplicated.
Reappeared ICloud Contacts and Calendars on the left bar of my Outlook!
Thanks for all the commentaries that I read, especially for PDiddy825!
