Here is an interesting one I'm interested if anyone else has come across or if we are the only people seeing it.
If you recieve a meeting forward notification in your oulook it will read the item as a calendar item. If I go to forward the item in my inbox its as if I open the calendar entry and am forwarding the the original meeting. in the inbox however its just a blank body email.
If I open the same item in OWA it reads it as the forward meeting notification email and displays the body as such. If I forward the same item from owa I can then open it in outlook as an email not a calendar entry.
The issue appears to be in the code rendering difference between the two applications. not sure if this is fixed in later rollups (currently Exchange 2013 SP1 RU5) or if this was introduced in one of these as we where not experiencing this fault before, and I'm unsure if it popped up when the system was updated not that long ago.
