Delete Enterprise Calendar

[Edwin_Derry_Iconsys]

I need some help deleting some enterprise calendars that were created in error. We need to remove them so that users cannot use them by mistake.

I go to PWA Settings > Enterprise Calendars, select the calendar I want to delete and then click Delete. I get a message saying "The calendar is in use by the following projects" and "Edit the projects to use a different calendar and try again".

I've checked all the projects listed and they are not using the calendar I'm trying to delete!

Thanks.

When the error message states that the calendar is in use in an enterprise project, this means that the calendar is either specified as the Project Calendar or has been applied to one or more tasks as a Task Calendar. To check if the calendar is specified as the Project Calendar, click the Project Information button in the Properties section of the Project ribbon. Do you see the indicated calendar in the Calendar pick list in the upper right corner of the dialog? If so, click the Calendar pick list and select a different calendar.

To determine if the calendar has been applied as a Task Calendar, apply the Gantt Chart view. Right-click on the Duration column header, select the Insert Column item on the shortcut menu, and then select the Task Calendar field. In the Task Calendar column header, click the Auto Filter pick list button (the arrow button). In the Auto Filter menu, select the checkbox for only the calendar in question and then click the OK button. Change the Task Calendar value to either None or to another calendar.

Hope this helps.

Hi Dale,
That’s exactly what I understood the message to mean, but I’ve checked the project calendar and task calendar on every task and this enterprise calendar is not used anywhere.
It doesn’t make sense.

Very odd. I suspect this may be a bug. You might want to open a case with Microsoft Support to see if they can troubleshoot and resolve this problem. Sorry I cannot be of more help.

@Edwin_Derry_Iconsys I had the same issue - I found that the Calendar I wanted to delete was included in the project under the Organizer > Calendar tab. Once I deleted the calendar from the Organizer view, I could delete the calendar from the enterprise.
