How to Fix Another Object with the Same Value for Property ProxyAddresses Error in Microsoft Teams

Microsoft Teams is a powerful collaboration tool that allows you to chat, call, meet, and work with your team members. However, sometimes you may encounter an error message that says “Another object with the same value for property proxyAddresses already exists.” This error occurs when you try to restore a deleted or renamed Teams group that has the same proxy address as another existing group.

What is a Proxy Address?

A proxy address is an email address that is used to send messages from a Teams group. It can be either an alias or a distribution list. An alias is a single email address that can send messages to multiple recipients. A distribution list is a collection of email addresses that can receive messages from one sender.

For example, if you have a Teams group called “Marketing Team” and you want to send an email newsletter to all the members of this group, you can create an alias or a distribution list with the same name and use it as the proxy address for this group.

  • Open Microsoft Teams and go to the channel where your deleted or renamed group was located.
