Hi community
Adnam, I think you mean everyone can see the event prior to approval.
If you go int the calendar list settings -> Version settings
set
Yes – Require content approval of submitted items
Optionally create a version of an event and if so, how many major or minor versions you want to keep.
Draft item security:
Only users who can approve items (and the author of the item)
—————————-
Obviously, you need to have a group with approval permissions if you haven't got one. That group can manually approve and event or via your OOTB SharePoint 2010 approval workflow. Once approved your members can further checkout to edit and your readers are at liberty to view the latest approved version….
Good luck.
BTW: how did you hear about me.?
