Apple Mail Old Alerts - No Outgoing Mail Server - Massive popup spam
So I had my one macbook pro shutoff for a few months due to house remodeling and when I opened it up to configure apple mail, I have a ridiculous amount popups for old calendar alerts that are probably a year or more old. I've tried removing and re-adding these accounts on this machine with no luck.. and basically I can't use apple mail at all. Running Big Sur 11.4 on a Macbook Pro 13" Retina Mid-2014
Here is a screenshot of what I'm looking at and have no idea what to do... I've tried also going into each email account and deleting a lot of old things, but that didn't seem to help much.
