Similar to email, MyCase lets you forward and share messages with other people. This is useful for when you would like to invite someone else into the conversation after the message was originally created.
To forward/share a message...
Open the message you'd like to share.
Click the Invite Users button (pictured below).
The Invite Users window will be displayed. Type the name of the person you would like to share the message with, then click their name from the dropdown menu. Note: You can only share messages with firm users and clients who have MyCase access enabled.
Once you have added everyone that you'd like to share the message with, click Invite Users. MyCase will then notify these people that a new message has been shared with them. In the message thread itself, everyone will see that these people have been added to the conversation (pictured below).
