 # Can't select Reply All in email messages with Microsoft 365 groups
 
-Consider the following example. You're a member of a Microsoft 365 group and you receive an email message addressed to the group. Using Outlook on the web or new Outlook, you select **Reply All** and then send the message. You receive an error that states that Exchange Online "Couldn't send this message."
+Consider the following example. You're a member of a Microsoft 365 group. You receive an email message addressed to the group.

 If you select **More details**, you receive this information.
 
-"This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later."
-
-## Cause
-
-**Reply All** isn't supported by design because a group uses a single email address.
+> This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later.
 
 ## Workaround
 
 To respond to an email sent by a member of a Microsoft 365 group and have the email sent to the entire group, select **Reply** instead of **Reply All**.
+
+## Status
+
+Microsoft is researching this problem and will post more information in this article when it becomes available.
