MY RECYCLE BIN
To access My Recycle Bin, go to the User menu at the top right-hand side of the screen, then select the Recycle Bin option.
From here, you will be able to see all of your recently deleted objects. These include Items, Documents, Sections and Agendas. Items will be available for 90days. 
To restore one object, you can select the Green restore button. The restored object will be placed back to where it was deleted from. 
If you wish to restore multi objects, you can select the check box on all objects you wish to restore. 
If you delete an entire agenda but only want to restore one item from it.
When restoring the deleted item, because it no longer has an agenda to be restored to, you will prompted to select a new agenda. 
ORGANISATION RECYCLE BIN
Resolve Users with Administrator rights may have access to the Organisation Recycle bin, allowing visibility and restoration of all User deleted objects from the last 90 days.
For this option to be available, the related Security Profile requires this setting to be enabled. Contact your System Administrator for assistance.
