Deleted my email account on iMac, need a new one
I deleted my email account on my iMac as instructed by my service provider to fix an email issue, but now I'm unable to create a new one on the mac. I was able to fix my iPhone 7 and macbook pro by doing the same thing, but the iMac keeps saying my user name and password are incorrect...Any suggestions?
iMac 21.5", OS X 10.10
