Meetings state 1 hour early

[quietas]

I have a single user (known to us at least) who is using Outlook 2003 with the 7.0.1 connector. The issue also occurs with the Outlook connector 6.0.10.

Essentially when we setup a meeting in Outlook at 8am for Bob and send it to a ZWC user John who sees 7am instead in the wording. The strange part is that the meeting will show 8pm in the calendar preview pane and then create the meeting for 8pm as well on John's calendar.

I attached a screenshot for easier reference.

Everything seems OK between ZWC users, is the Outlook connector not aware of Daylight Saving Time or have incorrect time zones? We're in Alaska (-9 gmt, DST used) if it makes a difference.

UPDATE: Edited the title

Could be a bug with a MAPI property, I suppose. Does it only happen with users in GMT -9?

I'm not sure really, I only have users in Alaska. My loaner laptop was out most of last week so I wasn't able to replicate the issue on another system yet. I'll see if I can duplicate the error on WinXP and Office 2003 this week, plus my own Win7 with Office 2010.

Hhhm, this seems to still be an issue in 7.1 with the newer as well as older ZCO software. Any ideas?

I've narrowed this down to our users with Outlook 2003 and ZCO. This bug was around with ZCS 6, 7.0, and now 7.1.

Below I pasted the original info for two meetings. One made in Outlook 2003, the other in 2010. I think it might make a difference, but 2003 does not include the TZ lines for Time Zone information. The 2010 meetings work and display correctly, while the 2003 schedule correctly but will not display in the message body correctly.
