Using New Outlook on Windows for personal email, calendar, and contact management
I would like more time to recall my messages. Up to a day.
Are you referring to the Undo Send? It is limited to 10 seconds. See the screen shot below.
.
The Recall Message command applies to messages after they have been sent. Initially, this command wasn't supported in the New Outlook, but if you have a recent version, the command has been (re-)introduced. Open your sent email in a separate window and look in the Respond group on the ribbon.
Note that not all account types will support recalling messages.
