Recently I had a strange behavior with my out of office (OOF).

As I was away I enabled the OOF, with the scheduling option (send automatic reply between this date and this date) as usual.

When I get back, I desactivated the OOF but colleagues and clients still continue to receive my OOF while they should not.

The solution found was to:

  • export my Outlook rules
  • quit and relaunch Outlook using outlook /cleanrules command
  • reimport my rules​
