  • Hi,

    Thanks for posting in SharePoint 2013 - Development and Programming.

    This forum is for developers discussing developing issues involve SharePoint product. Since the issue is more relative to exchange development, I would move it to Exchange Server: Exchange Server Development.

    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. 

    Thanks for your understanding.

  • The first thing I would suggest you do is try to connect to the Exchange server you want to connect to just from Remote powershell https://technet.microsoft.com/en-us/library/dd335083(v=exchg.160).aspx on the host your trying to run the code from. This will make sure you have all the correct versions installed, credential format and there are no other underlying issue that are causing your code to fail.

    I would also suggest you either use the UPN as the user or downlevel format (eg domain\username) when you specify the username which is what the errors is pointing you to.
