Let's say your post had typographic errors.
I can't tell as there may be an app called this or that. I really must take your EXACT words for such things when dealing with apps.
http://support.microsoft.com/kb/2563324 tells us that Exchange ActiveSync is possible but you see that note about Android 4 and yours is at 2.2.2.
My old Evo 4G is back at 2.something and my new phone is 4.something. However Microsoft's ActiveSync is not available for Windows 7 so I can't test this for you.
-> This means you get to work with your Exchange support staff to sort this out.
