Allow me to easily and intuitively update an invite without sending an email out to the group.

I often need to make a small change to an invite that shouldn't require blasting everyone on the invite list.

I've been using Outlook for two years and if I'm able to do this, I've not found a way that works reliably. I regularly feel embarrassed at work thanks to your software. I see little concern for users here. I'm a passionate detractor of Microsoft product as a result.
