Deleted email accounts keep being added back
macOS keeps adding older Microsoft email accounts that I deleted dozens of times from Internet Accounts in System Preferences. I removed the account entries also from Keychain Access. I have multiple Macs and multiple user account on these Macs and it happens for each user account and Mac. The issue does not occur on my iPhone where is also use Keychain syncing.
I am not the only one who has this problem and it's not limited to Microsoft but can also occur with Google account, see Deleted email account keeps being added b… - Apple Community (all those suggested solutions don't work).
Apple needs to better test syncing across multiple Macs and macOS users. I experience the problem since at least a year now. Very annoying.
