Hi @Zach Ruedinger ,
Welcome to our forum!
From your description, do you want to turn off reading pane in Inbox?
If so, you can refer to the following steps:
Go to the Inbox, click the View tab and then click Reading Pane in the Layout section and select Off.
If the Reading Pane is not turned off, you can reset all views to the default view: Press the Windows key + R to open the Run dialog.
Enter outlook.exe /cleanviews in the Open box and click OK or press Enter.
