I have one staff person (an admin assistant) who
constantly adds contacts to her boss's contacts.  (he has
given her full permission to add, delete, etc. to his
contacts)  All of a sudden the contacts that she adds do
not show up in her view of his contacts....they do show up
if you go to his computer and look at the contacts.  When
she adds the contact to his contacts...it appears for a
brief second and then disappears.  It does appear on his
computer.  Closing outlook (both sessions - his and her)
or restarting does not bring in the contacts that she has
added (when viewed from her computer).

Weird eh?
