If you are using the CLD cache option and you have moved one or more calendars to different back-end servers (or changed the name of the back-end server), might not be able to see the calendars on the new server.
If this happens, perform the following steps:
Clear the CLD cache. See 12.5 Clearing the CLD Cache in Calendar Server Version 6.3.
The CLD cache will be out of date if you moved one or more calendars to different back-end servers. To refresh it, you need to clear the cache so it will be rebuilt.
If that fails, confirm that you followed the correct procedure for moving calendar. This information can be found at:
Then, clear the cache.
