I am using EWS to schedule delayed delivery emails in advance for a package management system. When a package is "logged" the system creates two delayed delivery emails, one 7 days out and one 14 days out to remind the package recipient they have a package waiting for pickup.
When the package is picked up the system is supposed to delete the scheduled emails. This is where I am having trouble.
It seems EWS does not allow you to delete a delayed delivery email - you must use a desktop Outlook client to do so. Can someone explain the logic behind this? Are there any plans for future support of deleting delayed emails through EWS?
