Archiving is a process in which older or inactive information or data can be stored securely for a long period of time. For an organization archived data is important and may be needed for future reference, but it is only stored until the end of its retention schedule.
Office 365 is widely used by many people around the globe. Sometimes, Office 365 users need to archive their mailboxes. There can be multiple reasons behind archiving data. One reason can be they want to remove their data from the mailboxes but do not want to delete it permanently so they go for data archiving. Another reason can be the storage capacity of mailboxes etc.
The user can also try to archive Office 365 Mailbox to PST file format using SysTools Office 365 Backup and Restore Software. So, in Office 365 a user can set up the archive and deletion policy easily. This automatically deletes data items from the mailbox and moves the data items to the user’s archive mailbox. For this, a user has to set up a retention policy that is assigned to mailboxes. Basically, in this archiving process, the items are moved to a user’s mailbox after a specific period of time and simultaneously, also deleted from the mailbox after they reach a certain age limit.
