Can anyone suggest why when I click on an item, my computer is double clicking and if I am deleting an email, it double clicks on the next one and deletes it too!!  Someone suggested it may be an Outlook problem? 

After updating to Win8.1, nothing happens in Outllook when double clicking an email to open it.  Unable to delete from inbox.  Emails are received and can be sent, but not opened. 

Live.com has taken over as email program- unable to revert to outlook.

I have reset the presumably updated IE 11. 

Outlook functions fine on an older pc running XP.

Problem with IE opening ??

I have Windows 7 and up until now have been able to open attached files (.pdf, .doc etc) by double clicking on them in windows Live Mail. As of today I can not. I downloaded the latest version of Reader, cleared my history, temp files, Favorites website data,  in Internet explorer. I have checked to insure the extension is linked with the .exe program. When I right click on the data the "Open" choice appears but not the "Open With" choice. When I choose open or print, nothing happens. I can however select save and then open the file in the saved folder.
I cannot make calendar entries/schedule meetings in Outlook. Double clicking a time slot results in no action and right clicking shows the possibilities greyed out. I have rebuilt the database but that didn't help. Perhaps a coincidence but I recently upgraded to Mountain Lion.
When opening an email, I can only see the senders name not their email address. So for example it will show:

Mickey Mouse

If you hover over the name (assuming it is not in your address book) it it will bring up a window showing the name "Mickey Mouse presence unknown"
Double clicking or right clicking brings no options to see the email address.

If the contact is in your address book the on hover window will still say: "Mickey Mouse presence unknown" and then show the contacts telephone nos. If you click on the contact icon beneath this - it brings us the contact record - but no indication of which email address the email was sent from. So if your contact has multiple email addresses you have no idea which email address the email came from.

This is completely unlike entourage which will show the name and email address as follows: Mickey Mouse <*** Email address is removed for privacy ***>

Any ideas how I can get this to work in Outlook 2011 ??
