I added my iMessage account to my work MacBook and now I want to remove the account, but Messages won't let me.
I Signed Out of the account and deleted the message history, but now when I start messages it still prompts me to login with the account, and if I go to Preferences the account still appears (inactive) in the list and the Remove button (- sign at bottom) is greyed out.
Is there any way to remove the existence of the account completely?

OK, I figured it out but it's not straightforward. I figured it had to be stored in a .plist file somewhere, so I searched all the .plist files in
~/Library/Preferences
for ones that contained the Apple ID I used for iMessages. These were the ones:com.apple.ids.service.com.apple.madrid.plist
com.apple.ids.service.com.apple.private.alloy.sms.plist
ByHost/com.apple.identityservices.idstatuscache.5A488A33-7FF1-56F5-A3F6-CBC792D5C705.plist
When I searched for
com.apple.ids.service.com.apple.madrid.plist
on the web I found a link to a very useful answer on the Apple forums that also helped out.So basically, this is what I did:
Delete the .plist files I mentioned above (note, the last one with the UUID in the name is likely to be different for each user):
Then I removed all the chat history and archive:
Then I restarted the Mac just in case. Now the account and everything about it that ever existed on this machine is gone :)
