Our auto-OOO 'on holiday until 15 August' leaks presence externally
A full OOO text to everyone tells attackers when you're away. Splitting internal vs external messages fixes it.
Try this first
- 1Outlook OOO: set separate texts for 'inside organisation' and 'outside organisation'
- 2External version: short and businesslike, no specific dates
- 3Restrict external OOO to 'my contacts' rather than everyone
- 4For C-level: no external OOO at all, internal only
When to bring us in
If CEO-fraud attempts spike during holidays: turn external OOO off for leadership.
