Office 365 is an immense platform that gives seamless access to its multi-functionality features. You can easily create or store your data, including Word, Excel, Presentations, images, PDFs, emails, calendars, notes, and many more. Office 365 indulges with so many advanced features. Today, we will talk about the Archive mailbox.

It is an extra mailbox for keeping emails distinct from those in the inbox. Any user can access the archive mailboxes after they have been enabled to save their inbox emails there.

An archive mailbox has the advantage of giving you a central spot to store emails that are no longer needed and immediate access to them. Additionally, the user may keep their Inbox (main inbox) organized and accessible in this manner.

For the safety and security of your Archive mailbox, regular backups or exporting your mailbox into PST is a necessary step. It allows you to access your data anytime and anywhere, providing peace of mind in the face of potential data loss.
