CalendarSharing Object (Outlook)
Represents a set of utilities for sharing calendar information.
You can use the GetCalendarExporter method of a Folder object that represents a calendar folder to create a CalendarSharing object. The GetCalendarExporter method can only be used on calendar folders. An error occurs if you use the method on Folder objects that represent other folder types.
You can use the SaveAsICal method to save calendar information in an iCalendar (.ics) file for sharing a calendar as a URL, or use the ForwardAsICal method to create a MailItem for sharing a calendar as a payload.
The CalendarSharing object only supports exporting the iCalendar format.
The following Visual Basic for Applications (VBA) example creates a CalendarSharing object for the Calendar folder, then exports the contents of the entire folder (including attachments and private items) to an iCalendar calendar (.ics) file.
Public Sub ExportEntireCalendar() Dim oNamespace As NameSpace Dim oFolder As Folder Dim oCalendarSharing As CalendarSharing On Error GoTo ErrRoutine ' Get a reference to the Calendar default folder Set oNamespace = Application.GetNamespace("MAPI") Set oFolder = oNamespace.GetDefaultFolder(olFolderCalendar) ' Get a CalendarSharing object for the Calendar default folder. Set oCalendarSharing = oFolder.GetCalendarExporter ' Set the CalendarSharing object to export the contents of ' the entire Calendar folder, including attachments and ' private items, in full detail. With oCalendarSharing .CalendarDetail = olFullDetails .IncludeAttachments = True .IncludePrivateDetails = True .IncludeWholeCalendar = True End With ' Export calendar to an iCalendar calendar (.ics) file. oCalendarSharing.SaveAsICal "C:\SampleCalendar.ics" EndRoutine: On Error GoTo 0 Set oCalendarSharing = Nothing Set oFolder = Nothing Set oNamespace = Nothing Exit Sub ErrRoutine: Select Case Err.Number Case 287 ' &H0000011F ' The user denied access to the Address Book.
