| Make sure that the calendar to import shows up in Outlook under "My Calendars". For a illustration click here. |
| If you connect to a Microsoft Exchange server, you may need to list any public calendars under My Calendars in Outlook. To do this simply drag the calendar from the current grouping to My Calendars. |
| Depending on how the calendar was shared with you, WinCalendar might not be able to access the calendar. For this case try having the calendar shared with you using a different method... Outlook supports more than one method for sharing a calendar. Try using a different method. For more information refer to Outlook Help (search on "Sharing Calendar") or see this posting on Microsoft's website: http://office.microsoft.com/en-us/outlook/HA102504241033.aspx |
| Make sure the calendar name does not contain any non-alphabetic characters like: -~!@#$%^&*()_+{}|:"<>? ...if so rename the calendar (or have the calendar renamed if it is some else's shared calendar). |
| Try running WinCalendar with Outlook open in the background. |
| Depending on your Outlook Server settings, Network settings or Windows settings WinCalendar might still not be able to access the shared calendar. If the issue persists try contacting the your Outlook Server Administrator & ask if there is any setting that may prevent MS Office Addins from accessing shared Outlook calendars. |
