Outlook 2003, 邮件收发正常，但打不开收到的Task Request

[cecedeng]

Outlook 2003, 局域网内，邮件收发正常，能打开普通mail，但打不开收到的Task Request, Form之类的。报的错误是：“Can not open this item. An error occurred registering the form in the OLE registry.”

高手帮忙看一下，怎么解决这个问题？

I changed two files (Usrclass and Frmcache), see if it works...

“Can not open this item. An error occurred registering the form in the OLE registry.”

这个错误只在打开非普通mail时才报！
普通的mail都能正常打开。真奇怪呀！

哪位见到过这个报错的？谢谢啦
