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?

Thank you for the reply unfortunately it still doesn't work on all machines.
However the changes didn't break anything on previously working machines.
First let me apologize for double posting Ken Slovak politely yelled at me
for also posting in the VSTO newsgroup. Ken my apologies. Dmitry - I
noticed your app which works perfectly well on several machines I'm working
with for testing uses a different interface. Some sample code also on
outlookcode.com by Helmut Obertanner that was inspired by yourself that
doesn't use the Outlook Object Model. Is this another potentially better
more generic approach?

Thanks

That's exactly what I see on machines that my addin is running but is unable
to set and retrieve property values on. OutlookSpy shows empty properties
with the right name but no value when I click IMessage. On other machines
my code works great, it sets and retrieves properties using the code you
suggested just as well as it did before with the code I submitted previously.
I have saved the IMessage to text files via OutlookSpy. I can provide them
if you think it would be helpful. Did I say I appreciate the help, I do.
