Adding an entry to a Calendar in a shared public folder with VBA


K

Keith E.

I have a web application that stores vacation requests in
an Access database.
I would like to extend its functionality by adding a macro
to the Access DB that
would add the requests to a "Vacation Calander"
(alias: "VacationCalendar")
in a shared public folder in Outlook.

A subroutine that should do this is listed below. It works
great if the Calendar used
is an individual user's calendar. However, the following
line produces a "The server mailbox
cannot be opened because this address book entry is not an
e-mail user" error message, when the
"Vacation Calander" (alias: "VacationCalendar") in a
shared public folder in used.


Set objFolder = _
objNS.GetSharedDefaultFolder(objRecip, _
9) 'olFolderCalendar


The public folder has e-mail access enabled and appears in
the Outlook global address list.

Any insight would be appreciated.

Thanks in advance.

Keith

The message means exactly what it says: You can't use that method to get to
a public folder. It works only on default mailbox folders.

To get a folder in Public Folders, you need to walk the folder hierarchy
using the Folders collections or use a function that does that for you. See
http://www.outlookcode.com/d/code/getfolder.htm

The real question is, "How would I find the appointment that the user wants
to cancel?" To answer that you'll have to go back to the business logic of
your application and decide how you want the user to indicate that they want
to cancel a vacation. Once you've figured that out, you should know what
information you'll have available to look up the appointment. Once you have
an AppointmentItem object, you can use the Delete method to remove it.

To me that's obvious. It can be either:

...Subject or
...Start and .End

What I was looking for assistance with actual the code to
to look up the appointment.

Outlook provides the MAPIFolder.Items.Find and .Restrict methods for looking
up items in a folder based on certain criteria. Find would be better in a
case like this where you expect to return a single item. Basics on how to
use Find are covered in its Help topic. Searching on dates can be tricky --
