CloudExtend offers limited support for syncing shared calendars depending on the approach used. CloudExtend currently requires a calendar to be owned by an end-user in Google Workspace and have a corresponding Employee record in NetSuite. Only the primary calendar can be synced.
Google Workspace offers the following options for sharing calendars.
Approach 1 (supported): Share the user’s main calendar with someone so others can see the user’s schedule. Link
Approach 2 (not supported): Create an additional shared calendar to track group activities, such as project schedules, or coworker vacations. See Link.
Suggested Workaround:
Admins can create a dummy user and share their primary calendar and enable license for this dummy user in CloudExtend Setup. Since this is a primary calendar CloudExtend will sync with NetSuite.
