Calendar Invitations to External Invitees - DST

We’ve patched our servers and software as recommended by vendors. All calendars information is correct internally. When sending invitations externally, the external invitees are reporting the invitation is for 1 hour before the actual meeting time. Most, if not all, of the reports are coming from external invitees NOT using Notes. What could we have missed that would cause this? Could our firewall be altering the invitation as it leaves our system? Or is it possible that there are really that many unpatched systems out there…including Hotmail (I sent an invitation to my Hotmail account and the ics info displays the start time as one hour earlier than I scheduled from my Notes client)? Any help would be appreciated.

Hi Laurie -

That’s a great question and rather than try to go into it, I’ll post the reference and let you come back with any questions that remain. The first of the links below talks about the specific issue you are seeing and the second link is a higher level document about the problem in more general terms.

Thanks for the info. Since we are running on UNIX it sounds like the hotfix may be our best option.

Apologies - posted a response to another thread on this one and then didn’t catch it until I posted the updated I intended to do on this thread.
