Macbook Mail app, Email disapears after clicking "Accept"
I got an email from a business partner. When I open the email within the Mail app on my Macbook, a small header comes up with the options to delcine, accept, and something else. I assumed it must have been some sort of invitation. After I clicked "accept", the email disapears! It's not in any of my folders, I also checkeched the calndar app, thinking that the event would have been added there, but nothing was there either. I have an IMAP setup, so I logged into my websever directly and the email is GONE. I still need the information that was within that email, BADLY. Can anyone tell me where the email goes and how to retrieve it? I'm so sure that Apple didn't just compleltely delete an email from existence just because I accepted an invite. That would make 0% sense.
*Mail app is not an option to choose from under topics, so I selected Big Sur.
