One of our users is accessing their mailbox in Caching mode.

His secretary added an appointment to his diary which he was able to see. She subsequently deleted this entry but it still appears in his Caching mailbox. If he looks at his online mailbox it deosn't exist but in Remote or Caching mode it does.

I've tried running Hit The Road to update the caching mailbox but the appointment still appears.

I have recreated this issue on a test box.

We are running GW8.0.1 26/08/2009 client build 88138.

Does anyone have any ideas?
