    We have some queues set up in CRM 2011.   In Email Router config, can successfully 'Load Data' and publish but then in Event Viewer we are getting this error 26090.  I searched and found a few references to this error, but none of the remedies (some CRM 4.0) helped.  What else can we check?    Thanks

    1. Create a  trust between the computer running the email router and exchange server.
    2. Check the user defined in the incoming profile has access  to read the mail box.

    I hope this helps.

    Brian,

    Any luck with this I am getting the same issue. I have 2 email addresses that I'm using for email queues.

    The first one works fine. We created a shared mail box and gave the user assocated with the first mailbox access to the second mailbox. The second Mailbox throws the error. We created a user to use as a service account to access both mailboxes as the CRM Email Router for 2011 on line only allows me to specify a single user account and not to pass user credentials through CRM. This blew up completely with the same error. Any help on this would be appreciated.

    Thanks

    Dave
