Exchange needs your credentials - Exchange Online, Skype on prem RRS feed

  • Question

  • Hey All,

    Looking for some guidance on the right way to correct this issue, if it can be corrected.

    Environment:

    Exchange 2010/Exchange Online Hybrid setup.
    Skype 2015 on prem - no Hybrid configuration setup
    ADConnect, Pass-through auth with seamless SSO, password hash sync enabled (No ADFS on prem currently, ADFS 3.0 coming soon).
    Modern Auth ON for Exchange Online, ON for Skype Online, OFF for Skype on prem

    Once I move  a mailbox to Exchange online, Skype client prompts for credentials to connect to Exchange Online. If I put the credentials in, it works. I am trying to make it connect without this step.

    So, I am wondering what the fix is for this?

    Enable Modern Auth for Skype On Prem? Will this break any of the Exchange 2010 stuff? Still early in the migration.

    Do what it says ion this article about importing the oauth cert into Azure and configuring a partner? http://www.xlync.com/my-blog/Article/43/solved-online-meeting-icon-missing-from-owa-in-exchange-online

    Setup the Skype Hybrid?

    For any of these solutions, do the Skype FE servers need internet access to the O365 URLs?

    None of the above?

    Thanks!

  • Hi RichB PSGS,

    Does the issue happen to all SFB client in your environment?

    For this issue, please press ctrl and right click the SFB icon in the taskbar check if EWS and MAPI status is OK.

    Moreover, please check if your SIP address is the same as your SMTP address.

    About Hybrid environment, you need to ensure Microsoft Online Services Sign-In Assistant is installed on every user machine to avoid Skype client integration/credential pop up problem with exchange online.

    Skype client will perform EWS request to Exchange mailbox every 30mins to get mailbox free/busy information and update Skype client presence accordingly. This means that both autodiscover and EWS requests should be working.  Autodiscover traffic goes to internal exchange which later gets redirected to exchange online, ensure this traffic does have any hindrance by network device. You can trace it using either fidler or even from client logs internally.

    Hope this reply is helpful to you.


    Regards,

  • Thanks for the reply Alice.

    Sip address and SMTP address are the same

    Installed the Microsoft Online Services Sign-In Assistant, but it did not resolve anything.

    Autodiscover and EWS are accessible from the workstations, and Outlook is working properly

    EWS and MAPI status bot show not connected.
