You cant browse, but you can search
Since IMSMO 2.0.1 client we have had the
ability to search your company directory. Just enter a value and
click Check Names (or control-K) to resolve (and if multiple matches you
can select the correct one)... or you can click the To field and search
there and see all the matches and choose the correct one, viewing more
properties if needed to determine.
There is not a way to browse the company
directory without first performing a search.
