New staff and students joining from July 2026: Update to University email storage

From 1 July 2026, all newly created Outlook email accounts (Microsoft Exchange Online mailboxes) will be subject to an eight-year email retention policy.

What does this mean?  

Emails older than eight years will be automatically removed unless they have been actively retained using an alternative retention policy. 

This change is being introduced to support improved data governance, strengthen email data lifecycle management and reduce the unnecessary long-term retention of email data across the University.

Please note: existing mailboxes and existing email content are not affected as part of this. 

Where there is a business requirement to retain emails beyond eight years, colleagues will be able to do so by creating a mailbox folder, applying an appropriate retention policy to the folder and moving relevant emails into it. 

For instructions on how to apply retention policies to folders, please visit the IT Services website.
