If you have deleted emails in Office 365, there are a few things you can do to recover them.

  1. Look for the email address that was used to send the email. This will help you find the email in your account and extract it.
  2. Copy and paste the email address into a new message or document and send it to yourself. This will help you keep track of where the email is located and make sure that it is recovered when needed.
  3. Use a search engine to look for any remnants of the email in your account, such as drafts or attachments. These will help you find and extract the deleted emails more easily.
