In prior versions, after I sent an email(A), i could hit back key and it would show email(A) exactly as it was prior to pressing "send"

 as if it had not been sent. What happened to that feature/behavior?

THIS WEB PROGRAM ON YOUR COMPUTER.   That statment is in yellow, then in the main content of the message it says: the program will open outside of protective mode.  Internet Explorer's PROTECTED MODE helps to protect your computer.  If you do not trust this program, do not open the program.

NAME:  Silverlight.Configuration.exe

PUBLISHER:  Microsoft Corporation

 

then it asks if I want to allow or not allow - except my screen is COMPLETELY frozen.  I can't delete, check the allow or do not allow, nothing.  I have to shut my computer down to get out of the hotmail system.  Do I have some kind of virus?  What can I do to get this fixed?  Any help will be greatly appreciated.

I am trying to open some old messages but I get the following message "'The message you selected could not be found. It may have been moved or deleted. Please click the folder again to refresh the view'''. These are important messages that I need to open. HELP PLEASE

I have recently moved our organisation to an OSX server running Mountain Lion. We have a variety of Mac clients within the network that all authenticate to an Open Directory. All clients run Outlook 2011 and connect to a hosted exchange platform. Two 10.6.8 Snow Leopard laptops run both Outlook 2011 and Entourage 2008 side by side and each client connect to different hosted platforms as we run multiple domains and one of our mail servers is not compatible with Outlook 2011 as it is pre Exchange 2007.

We have in the last 24 hours created mobile accounts for the two users who are on the laptops. Since then we are seeing a great deal of sync errors being reported on those clients all relating to the Outlook database which obviously exists effectively in two places - on the server and on the client machine. Beyond the irritation of being interrupted frequently by the OS telling me it is having trouble with the synchronisation I have not yet noticed any major problem, but my question is whether or not I have done something that is not supported. Should I be excluding the Outlook database from the sync. Obviously what I am trying to achieve is a situation whereby the laptops can be removed from the office network and used in a remote location without Outlook complaining that it cannot see its database. Anyone have any thoughts or experience of this?

Many thanks for reading.

This new "Lightning" thing makes it impossible to get to my pdf records. I've tired putting in my usual password and it doesn't work.  I've tried changing the password and that didn't work.   I'd rather they go to Word Perfect so I can just open and/or print them. 
I have uninstalled and installed Adobe 10. I have installed an earlier version of Adobe, as I was able to open PDF attachments earlier. I have installed and uninstalled Microsoft Silverlight.
