An attempt to create or manage an email account fails with the following error:

unable to update the mail account properties. Can't open domain. Domain domain.tld. Reason failed to login (Error code 1)


Synchronization issue between mail server and Plesk.


Run mchk utility for affected domain, but before running this utility please read What does mchk command do article:

"%plesk_bin%\mchk.exe" --domain --domain-name=domain.tld --fix=local

If you use SmarterMail and the issue persists, please try the solution described in the #118961 article.

Other Information: The supplied user is working, but the underlying issue has not been corrected. user accounts are being created with account id 0 and no entry in dbo.accounts table is being created. the means new accounts do not have passwords stored in plesk. it includes ftp accounts. More Information: I tried deleting the account and recreating it. Didn't work. So I deleted the account, deleted the site from IIS, deleted the app pool from IIS, deleted the directory from c:/inetpub/vhosts, removed every reference to the site from the psa database... so the server should have no knowledge of the site, and tried creating it again and it still gives the error: Error: ProtDir_IIS::update() failed: Add Protected Directory failed: columns siteId, path are not unique (Error code 1)
