There are no error messages and so far she is the only user i have heard of with this issue unfortuntely.

The short and skinny is when she double clicks on attachment, nothing happens. Then she tries to right click and save but, the save option is greyed. So then she keeps clicking several times and one of the docs opened(not sure of type). So i asked her to fwd me one of the offending emails and it opened fine for me. Then she was fwd'd the same message and it opens no problem.
 

Hi Trent...

We still need more info here...

Does this happen all file-types or is it specific to a certain set?

E.g. do text files open but MS Office attachments not open?

This happens to all attachments pre-upgrade right? All attachments sent to her post upgrade open ok?

Thanks,

Paul
