How does M365 Exchange Online Archive work?

  • The default policy automatically moves your mail & calendar items that are older than 1 year into your Online Archive mailbox. 
  • Your folder structure is retained when items are moved into it.
  • It is available through the Outlook client and Outlook on the Web (OWA).

The Outlook Archive Folder is found within your own mailbox. It is a legacy pre-created folder and is like the folders you can create yourself. It provides no additional benefits.

Should I use M365 Exchange Online Archiving instead of using a PST file?

Yes, M365 Exchange Online Archiving is recommended for your VUMC mailbox.

  • Outlook’s PST file is not recommended for use with your M365 mailbox. Online Archiving is specifically designed for M365 mailboxes and offers enterprise archiving features. The .pst file type, a personal storage table, can contain messages, emails, calendar events, email addresses, etc. This file type is not recommended for network shares and cannot be used in a cloud-based environment, like M365.
  • Risks in using an Outlook PST file:
    • Possible corruption of the PST file
    • Possible complete loss of the PST file from a device
    • PST could cause Outlook client not to open
    • PST file NOT accessible from the web
  • 365 Online Archiving removes all these risks. You can even drag your PST mail items into your Online Archiving Mailbox and stop using PST file altogether.
