Are there any fields in outlook (connected to an office 365 mailbox) which may help determine when an email was opened/read?

As far as I know, there is no such information stored in Outlook. You can just see the time when the email was delivered.

It might be possible to see if the recipient has read an email or not using Powershell but you cannot track the time.

Morning,


Can't be done, the only function that offers this is a "Read Receipt" and that function only works if the other user allows it from his client.
