Filtering by archived
If, at any time, you would like to revisit your archived communication streams, you can click on the "Filter" icon to the right of the "Archive" icon at the top of the column on the left side of your "Inbox.".
This will open a window that shows the "Date Range" tab by default.
You will need to select the "Type" tab from this window and click on the "Archived Messages Are Shown" in order to include archived communications. You can toggle this option off at any time.
You can then click outside of this window to return to your inbox.
