Can CORE import data from Microsoft Planner?

No. BQE CORE does not provide a direct integration with Microsoft Planner. Data from the Planner app cannot be imported automatically into CORE. If needed, you can manually export data from Microsoft Planner (for example, to Excel) and then import it into CORE. If you would like to send this for a new feature request, submit it to our team at CORE-Ideas@bqe.com or post it on BQE CORE Community under Feature Requests.
