Outlook 2007 on Exchange can not accept appointments sent from Lotus Notes

We use Outlook 2007 on Exchange Enterprise 2003.  When receiving appointments sent by Lotus Notes the appointment comes through as a standard email with the actual appointment as an attachment.  
When this attachment is opened the 'Respond' area is grayed out with no Accept, Decline, etc buttons.
It also says 'As the meeting organizer, you do not need to respond to the meeting'.  Clearly my user is not the organizer....

Anyone shine some light on this?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Depends on what version of Notes the sender is using ?

If not at least R 6.5, then there are compatibility issues with ical  type of meetings etc.

I hope this helps !

Ok so after digging around a bit I found this:

if I log in as the user using OWA, the meeting email comes with an .ics attachment which when clicked on loads into Outlook and I can click 'Accept' as normal.
So it appears that for some reason when this attachment is loaded into Outlook directly it is converted into .msg format.

I found this link:

I've applied the fix and think that it will take effect next time one of my users gets an .ics meeting, so will just have to wait and see....
