1) I have seen other MVP's say that when a UserProperty is added the item
should be saved , can you safely add many items (like many user properties)
before actually saving the item?

2) I am working on an Outlook addin that works great on my dev machine but
appearantly doesn't save/read userproperties for appointment items but task
items appearantly read/save fine on most systems.

1.Yes, you can set any number of properties before calling Save
2. Provide the relevant snippets of your code and indicate what exactly does
not work.

Please use my comment for your product OutlookSpy: WOW! It does what it
says!

As hard as it was to articulate the differences between two systems with
your tool I think I may have found something, finally.

Dmitry although it does require some explaination - looking at the IMessage
GetProps tab I see lots of differences in number of properties with each
Appointment item and values. As I suspected my userproperties have no values
in the system/version that doesn't work. one property that is interesting is
http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/urn:schemas:calendar:version.
BTW the value is 2.0. I don't see this one on systems that do work for my
Outlook Addin. Do you know what its for?
Can you offer an explanation why aren't my properties storing values? Is it
possible my properties somehow depend on the property offset?

What is your code that sets the propeties and saves the item?

Ok here's what I got:

Microsoft.Office.Interop.Outlook.AppointmentItem appt;
string propertyName = "MyProp";

// if the property doesn't exist
if(!appt.UserProperties.Find(propertyName,Type.Mis sing))
{

appt.UserProperties.Add(propertyName,Microsoft.Off ice.Interop.Outlook.OlUserPropertyType.olText, Type.Missing, Type.Missing);
}
appt.UserProperties[propertyName].Value = value;
appt.Save();

Try the following instead:

UserProperty prop = appt.UserProperties.Find(propertyName,Type.Missing );
if (prop == null) prop = appt.UserProperties.Add(propertyName,
OlUserPropertyType.olText, Type.Missing, Type.Missing);
prop.Value = value;
appt.Save;
