Is there a way we can hook into an outlook appointment form and run some validation logic prior to "Send".
For e.g. our business requirements are somewhat like this.
- Populate your meeting request by some means. We have some addin feature that does this.
- Click on Send. Normally this should actually "send" the email. Instead of this, I need to validate with respect to another service, and post successful validation I should allow the "send" else cancel it.
How do I do this in outlook addin?
