Was logged in as Admin. Got kicked out. No changed to account but now it shows locked out. Went through the whole process of stopping the mail service, and IIS site. Edit the mailconfig xml file in an elevated process. Deleted the sysadmin lines.
FIXED by copying the original mailConfig_bak.xml as mailConfig.xml restarted mail service. What a nightmare.
BROKEN 20 minutes later it locked me out again. Downgraded from latest release. STILL CANT GET IN. Looking for new email server software cause I can't have this nonsense.
