Beginning with Outlook 2007 SP2, Copy: is prefixed to the subject of meetings when they are copied within a calendar or to another calendar.
From the release notes:
"A meeting that is copied from a shared calendar does not indicate that it is a copy. SP2 adds "Copy:" to the subject line."
Copy: was added so users would know how the meeting ended up on the calendar and why it wasn't updating. There is no way to avoid it in Outlook 2007 SP2 or Outlook 2010, except by not copying the meetings. Note that even though the release notes say "copied from a shared calendar", it applies to all copied meetings. Any time you make a copy of a meeting by copying it to a new date, copying it to a second calendar in your mailbox, or export it to a pst, Copy: is added to the subject.
You can edit the subject line or use VBA to remove it.
The Infobar on meeting will say if the meeting was copied. Copy: won't be added back to the subject if you copy it again.
The following methods did not add the Copy: prefix to subject lines in my tests:
- If you are using a pst, copy the pst file then move the meetings from the pst copy to the second Outlook. Moving the meetings will preserve their ability to accept or send updates.
- If you are using Exchange server, use Outlook 2003 to export the calendar.
- Create a new pst. Right click on the calendar and choose Copy. Select the new pst as the destination. Outlook will copy the items then complain it can't copy the folder. Open the pst in the second Outlook and move the calendar items.
Below is a VBA script you can use to cycle through every appointment item in the selected calendar and remove the Copy: prefix. Works in Outlook 2007 and 2010. (Also works in older versions, if you need to mass-edit the subject line.)
Sub RemoveCopy() Dim myolApp As Outlook.Application Dim calendar As MAPIFolder Dim aItem As Object Set myolApp = CreateObject("Outlook.Application") Set calendar = myolApp.ActiveExplorer.CurrentFolder Dim iItemsUpdated As Integer Dim strTemp As String iItemsUpdated = 0 For Each aItem In calendar.Items If Mid(aItem.Subject, 1, 6) = "Copy: " Then strTemp = Mid(aItem.Subject, 7, Len(aItem.Subject) - 6) aItem.Subject = strTemp iItemsUpdated = iItemsUpdated + 1 End If aItem.Save Next aItem MsgBox iItemsUpdated & " of " & calendar.Items.Count & " Meetings Updated" End Sub
Select the calendar that needs fixed.
- Press Alt+F11 to open the VBA editor. (or Tools, Macro, Visual Basic Editor)
- Expand Project1 then double click on ThisOutlookSession to open the code window.
- Copy the code above (click in the text, Ctrl+A to select all, Ctrl+C to copy)
- Paste it into the code window then Save.
- Press the Run button.
To run the code later, press Alt+F8 (or Tools, Macro, Macros), select the RemoveCopy macro and press Run.
