I'm curious about the capabilities of IT administrators when it comes to managing emails in Office 365. Specifically, can an IT admin delete emails from an employee's sent folder without their knowledge? Would the employee have any way of knowing if this happened? Also, how are deleted emails handled in terms of recovery from backups?

Yes, a global admin can manipulate any mailbox content. However, the deletions are logged—all actions are captured in audit logs that higher-level IT staff can access. Recovery is possible if the organization has proper retention policies in place.
Absolutely, if an IT admin needs to, they can remove emails from any folder, including sent items. However, those actions are usually logged in an audit trail, so while an employee might not know it’s been deleted, sysadmins can track those changes.
Yes, admins can definitely delete emails from a sent folder without the employee knowing. In Office 365, it’s possible to use features like the Hard Delete function through KQL query results if you have a high enough license level. As for recovery, if the emails were on the server for over 24 hours, there's a good chance they could be restored from backups.
Been working with Exchange for nearly 30 years, and yes, we absolutely can delete emails from sent items. Deleted emails won't trigger any visible alert on the user's side, but audit logs will reflect those changes, especially in case of legal inquiries.
If you're worried about this happening, I suggest keeping an eye on your mailbox activity. While it’s technically feasible for admins to delete, there are rules around email retention and auditing that should ideally protect against misuse.
