I have had trouble receiving email on one of my accounts. I have deleted the account in System Preferences and have attempted to add it again. I now get an error "This account already exists." I cannot see it in the list of Internet Accounts and it has been removed from my Apple Mail. Any ideas what might be the cause, please?
MacBook Pro with Retina display, OS X Yosemite (10.10)
HA! This post helped me with a different issue. One email account was active but the second wasn't. Error message: "Only one mail account can be enabled on this Mac." I've always had two, but had transferred data yesterday to a new macbook and suddenly this appeared on my desktop. After trying for hours, I saw this post, read down and saw Jim Ward's post about Google. BINGO! Deleted Google and got both mail accounts back! Thank you all!
This post solved the issue for me mail says "this account already exists" but it's nowhere to find
Sorry, I solved my own problem. My email account was "linked" to my iCloud account. I deleted my iCloud account first. Then I could add my email account that I had deleted. I then aded back my iCloud account. Fingers crossed it all now works.
I'm having the same problem. How do you delete your iCloud account? Thank you.
I think I just used System Preferences>Internet Accounts then selected iCloud and the "-" to delete it. I then added the account I was having difficulty with. When that was complete I added back my iCloud account. Good luck.
very good, very helpful, and successful
This worked like a charm. Took about 30 seconds! I'm sorry I didn't find it before I spent 2 days trying to figure out what was wrong!
This did not work for me. I also use my Comcast email as my AppleID. I deleted the iCloud account. Used iCloud system preferences to log out of iCloud. Looked in Keychains for any reference or old passwords. Removed all SMTP server references to the old email account.
Try going to System Preferences/Internet Accounts and delete the account there.
The problem turned out to be a Google account, not used for mail, that used the same email address I was trying to restore. I was focused on iCloud and didn't even think of Google.
Thank you for your help.
