Unknow error with methods ReplyAll and Forward

[Bingo]

I've a Outlook Mail Item, oMapiMailItem and I need to
create other Mail Items off this one by using ReplyAll
and Forward.


' Reply All
Set oMapiMailItemReplyAll = oMapiMailItem.ReplyAll

' Foward
Set oMapiMailItemFoward = oMapiMailItem.Forward

I got a run-time error for both. It's unknown error!

I've been running the same code for quite a while and
this is the first time I got this unknow error.

Any help will be appreciated. Thanks.

This only happens with certain emails. I'm still
checking to see why this happens.
