Retention Policy for Deleted Email on MS Office 365

  • Email deleted by a staff, student and alumni (collectively known as “user” hereafter) is moved to the Deleted Items folder of the user’s email account, which consumes the user’s email disk quota. The email in the Deleted Items folder can be retained as long as required by the user for the purpose of restore as required.

  • After Empty Folder (a user command to purge Deleted Items), purged email will be moved from the user’s Deleted Items folder to a separate (central) MS Office 365’s Deleted Items folder, and the disk quota of the purged email will be recovered.

  • The purged email will be retained in MS Office 365’s Deleted Items folder for a maximum of 30 days, during which the user can still restore the purged email from MS Office 365’s Deleted Items folder before it is permanently deleted after 30 days.

  • The above retention for deleted email is not applicable to users who do not use Office 365 email direct, e.g. users who Redirect, Fetch, Connect email from Office 365 to Google, Yahoo, or other external accounts.

  • For staff leaving the University, in accordance to the Computer Account Retention Policy for Leaving Staff, his/her email account and all account content will be permanently deleted immediately without any retention, on the date following his/her last day of service, or on the expiry of grace period/extended grace period, if applicable.

  • For student leaving the University without graduating from a CityU academic programme, his/her email account will be extended for 60 calendar days (grace period) after his/her last date of studies, if the University and the department of him/her have no objection. On the date following the expiry of grace period, if applicable, his/her email account and all account content will be permanently deleted immediately without any retention.
