When you no longer need an Inbox message, you can archive it. Archiving a message will prevent you from receiving further notifications from that discussion. After you archive a message, you can also delete it from the Archived section.
In the top-left corner, click your ministry hub then Connect. Then click Communications > Inbox.
Click the message.
In the top right corner of the message, click and select Archive.
This moves the message to the Archived section of your Inbox.
