You are trying to read emails from an Office Shared Mailbox, such as <account email address>\suffix (with the shared mailbox suffix).

But the Read Email Process Action is throwing an error such as "AUTHENTICATE failed":







  • Stambia Designer DI and Stambia Runtime S20.2.0 or higher


To fix this issue, an additional property with KeyValue has been created on Email Metadata/Incoming account, to provide additional properties necessary to be able to establish a connection, with IMAP.

Thus, to read mails on shared mailbox, two of those properties are necessary:

  • mail.imap.auth.login.disable=false

  • mail.imap.auth.plain.disable=true
