Everytime I try to send a message with Outlook (or any kind of Windows messaging applicaton) a mapisp32.exe error occurred. What ca I do? Please help me, thanks.

Is the error message you're getting Mapisp32.exe caused an access violation fault in Kernel32.dll ? If it is you could have the happy99 virus. Go to start>settings>folder options> click on the view tab> look for hidden files> select show all files. Search for ska.dll, if you find it follow these steps. Click Start, point to Find, and then click Files or Folders. In the Named box, type Ska.*, and then click Find now. In the found items box, right-click Ska.exe, click Rename, and rename it Ska.old. In the found items box, right-click Ska.dll, click Rename, and rename it Ska.bad. Click New Search and in the Named box, type Wsock32.*, and click Find now. Rename Wsock32.dll to Wsock32.bad, and rename Wsock32.ska to Wsock32.dll. Click New Search, and in the Named box type Happy99.exe. As you did in the steps above, rename Happy99.exe to Happy99.bad.

I need the exact error message also have you installed a anti-virus package recently?
