Hi, everyone,

I've developed one user defined appointment item in Outlook and I have
one combobox which is filled when the form is opened. And the input of
the combobox is limited to the list. So if the user inputs some invalid
value. Outlook will output one error message. Regarding to this
combobox I have now the following questions:

1. May I customize the error message of Outlook while the user gives
any invalid values?

2. If the user send this appointment to other ones, the form is changed
automatically to IPM.Schedule.Meeting.Request. When someone opens this
kind of form, the combobox will not be filled. So the user will always
get some error messages.

I'm looking for a solution without customizing the
IPM.Schedule.Metting.Request form.
The first idea of mine is to set MatchReqired = True only when the user
opens the user defined appointment item. But I tested with
Item.GetInspector.ModifiedFormPages("UserDefined") .Controls("combo").MatchRequired
= True, but it doesn't work.

Has anyone a suggestion?

3. My another question is if there is any other ways to fill in the
combobox. The ENTER action is unfortunely not supported in VBScript.

Thanks a lot

Lucia
