    Hi Larry

    i have checked a couple of other accounts (as well as the new account I created as per above) and they have no safe or blocked senders in them.

    as mentioned previously I can't even move a brand new account to O 365

    Hi Martin,

    Thanks for the updates.

    I'd like to confirm whether the affected mailboxes are actually moved besides getting the error message.

    Regards,

    Robert

    Hi Martin,

    Thanks for the updates.

    Can you please do the Outlook Anywhere test for your Exchange server, after the test finishes, please click Expand all and send us the complete results through private message. Here is the link:

    Outlook Anywhere test.

    Please re-run the HCW in your Exchange server and to see if there are any errors.

    Meanwhile, please tell us what certificate in your Exchange server, the self-signed certificate or the third-party certificate.

    Regards,

    Robert

    Hi Robert

    i have sent through the Outlook Anywhere test results to you

    I have a third party wildcard certificate on the server

    When you say HCW do you mean the Hybrid Config Wizard you run at the start on the Exchange server?
