Hi Guys,
We encountered quite a strange issue.
User's on our Zimbra platform using IMAP with personal calendar, are having issues sending meeting invites to external Exchange server, from Outlook 2010, where the body shows up blank of the meeting.
I tested this using IMAP account with personal calendar using Outlook 2007.
The remote user on Exchange ( 2003 ) receives the meeting request body without any issues.
Using the same account, with Outlook 2010, the meeting request arrives at Exchange side with Body blank.
Below is how the calendar as received on remote server
Code:

We don't use Daylight savings Time, and our location is GMT+2
What I did notice that is strange, is the following in the calendar body :
TZOFFSETFROM:+0300
TZOFFSETTO:+0200
There appears to be a 1hour difference, which is strange considering we dont use dst, and I am tempted to think this _might_ be what's causing the issue.
Anyone else had similar issues to External Exchange servers?
