If you only need Office 365 emails from a particular period, using a date filter can help limit the backup to the required data. Instead of saving the complete mailbox, you can specify the relevant start and end dates and process the messages that fall within that period. This is useful when you need a focused backup of recent or older mailbox data without including unrelated emails.

For this backup Office 365 requirement, Aryson Office 365 Backup Tool  provides a date-filtering option that lets you specify the required date range before starting the backup. You can select the Office 365 mailbox or folders and then define the dates according to the data you want to save. The tool supports saving the selected mailbox data in formats such as PST, MBOX, EML, MSG, CSV, and PDF. If you need to backup Office 365 data for a specific period, the date filter provides a practical way to control which emails are included.
