This article provides the steps to create (export) and save (backup) an Outlook Data File (.pst file) in Windows or iOS.
In Outlook, the "Schedule Sending" feature allows you to compose an email and then schedule it to be sent at a specific date and time in the future. This can be useful if you want to compose a message in advance but prefer to have it sent later, such as during business hours or when the recipient is likely to see it.
Teams meetings can be scheduled directly from the Teams calendar, but they can also be scheduled from Outlook if needed.
