Just an FYI for those working on the DST change with Exchange - on 2/22/07 they updated
the order in which patches are applied so that now they recommend not apply the Exchange CDO patch until after the users calendars are rebased. Previously they were saying to apply the Exchange CDO patch before rebasing. Apparently the change was due to a problem they discovered with the CDO patch and OWA that would allow a user to create a recurring meeting in OWA that would not get fixed with rebasing.
They have also realeased a hotfix for the CDO patch for a rare issue that caused the stores not to mount after the patch was applied:
930241 The Exchange 2003 database does not mount, and event IDs 9518 and 9519 are logged in the Application loghttp://support.microsoft.com/default.aspx?scid=kb;EN-US;930241
The hotfix can be downloaded from here:
For anyone who has used the workaround outlined in:
