There are several ways do perform such action.
- by setting a custom requirement
- by using a rule set (recommended, but professional tools must be activated)
Please let us know how you created the setting
BTW 23-26 june is not available on your calender !
Thank you for your speedy reply.
I used a custom setting requirement, when I look in my calendar I can see it as available. Does it just take a while to activate?
Or how do you do a rule set, and how do you activate professional tools?
