Linking an Email

Just as you would expect from the search bar in Browse Cases within MerusCase, this will automatically bring up suggestions as you type. Select the desired case name. If you wish to change this later, click the X next to the case name.

In order to use this add-in, you will need to make sure that email sync is set up, as well as that the email you're currently trying to link has been synced to your MerusCase (which can take up to 10 minutes).
