Please note that currently the Scheduler supports only recurrence rules in rfc5545
format - that why you should either describe new field in the dataBase where the Scheduler to save it's recurrence rule or manually parse the Office365/SharePoint recurrence rule format to the rfc5545
Also I would suggest to share your idea of implementing such build-in support in Kendo UI UserVoice
. Most voted ideas are included in next Kendo UI releases.
