Allow any user, regardless of their email client, to receive planner notifications
We are forced to use GSuite for our email and we are using SPO with the standalone SPO Plan 1 licensing. It appears that none of our users can get Planner notifications when a task is assigned/upcoming/past due because we don't use Outlook. Remove this restriction and allow notifications to be sent to any email address regardless of the client used. We currently receive SP alerts without issue.
