I have Optusnet as my internet provider, and have a Optusnet email address. I have this linked to Outlook on my PC. I've discovered that if I delete an email from my Optusnet files it is automatically deleted from my Outlook files. How do I prevent this?
What device are you using when you delete Optusnet files? What version of Outlook are you using?
My understanding is they should stay in the Deleted folder for 7 days, if this isn't happening you may need to please Chat with us for support.
