This macro allows adding a calendar with the same name as an existing calendar. This includes calendars on wiki pages, other calendars in the database, calendars that have been removed, calendars on pages that have been removed or purged, and calendars in wiki spaces that have been removed. For this reason, when entering a name for a calendar, enter a name that is likely to be unique.
About setting restrictions on a calendar
Avoid restrictions for calendars created with the previous Confluence calendar macro, rather than the Team Calendars macro.
