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.

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.
