Hi all,

I need to change reccurence rule for existing appointment. I tried to
do that via WebDav. Here my steps

1) Search calendar folder for master appointment
2) Update rrule field for master appointment (proppatch method)

After that i get a strange bug. In OWA this appointment becomes
unvisible. In Outlook appointment is visible but not highlighted in
calendar. When i open this appointment for edit in Outlook, go to the
recurrence dialog and simply press OK without any changes this problem
is solved - appointment becomes visible in OWA and highlighted in
Calendar.

What i need to do to force recurence rule update or what a doing wrong?

Thanks,
Alexey

Usually if your setting or modifying the Rrule via WebDAV after you have
made your changes you should run a expansion query against the calendar
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/e2k3/e2k3/_cdo_enabling_recurring_appointment_expansion.asp .
You can use the code sample from
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/e2k3/e2k3/_exch2k_searching_calendar_folders_webdav.asp
and just change the start and end date.

Cheers
Glen

Hi Glen,

I tried to do eхpand search (for year), but this not help.
Unfotunatelly, WebDav find only one appointment - my Master Appointment
:( . But then i open it for edit in outlook and simply open recurrence
dialog and close, appointment begins work correctly. Maybe i need
change not only rrule field in master appointment?

I use Exchange2003 and OfficeXP

Thanks,
Alexey
