After changing the Advanced Settings Tool in Unity UM 5.0(1) I have one user reporting they aren't getting Outlook read receipts in email anymore. We were trying to disable having the phone play the receipt as a voicemail. I'm trying to find another user to confirm this problem in Outlook.

User requests a read receipt for email, and read receipt was received via voicemail, mwi on phone would light.
After Advanced Settings Tool change
User requests a read receipt for email, and no read receipt is received.
