Hello, @Technician123, you don't have such a possibility. Outlook Web App is purely meant to send and receive email but does not have a backup option.


If you want to back up email to an external medium, you will need a client such as Microsoft Outlook that supports this.


So, in order to make a proper backup, configure your account in a mailclient that supports making a backup. Just because OWA does not support it, doesn't mean it's not possible. In modern mail clients such as MS Outlook, just entering your email address and password automatically configures the client using autodiscovery.


This thread can be useful in your case. One more suggestion is to discover more documentation about Microsoft 365 backup with the help of third-party apps, as you should think in advance about your data safety to be prepared to any unpredictable situation.
