Have a user running Gw2014 sp2 (build 120664) and she has an
appointment that does not show up on her calendar.

To clarify, she has proxy access to about 8 other calendars, all of
which show up on her multi-user calendar, *and* her own calendar has in
the area of over 4000 items in it.

The properties of the appointment sent item shows she accepted it, it
just does not show in her calendar, tried F5, exiting and restarting
the client, rebooting the machine, none of which work.

Any suggestions? Running stand-alone gwcheck on her account right now.
