Email archiving can be enabled for Microsoft 365 to give another 100 GB of online storage of your emails that are not actively needed on a regular basis. This gives you space in your active inbox and folders that are used on a daily and weekly basis. The content can be accessed via the Microsoft 365 portal and/or the Microsoft Outlook for Mac and Windows apps. Once email archiving has been enabled for a mailbox, the online storage folder will be created. Content will gradually be moved over to the archive.
