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
