Unauthorized 401 error testing connection to EWS Mailbox

Article # 3030988 - Page views: 784


I encounter the following error when testing EWS mailbox in Kofax Import Connector 2.3 KC-Plugin Configuration ¦ Connection ¦ Import Connector ¦ Mailbox Import:

Connection to EWS mailbox on https://.../ews/exchange.asmx cannot be established. Error message:The request failed. The remote server returned an error: (401) Unauthorized

How can I resolve this issue?


It has been observed that changing the User name field in the Mailbox Import setting from username@domainname to domainname\username can resolve this issue.

Verify the username and make sure you're using the correct password.
