Dynamics CRM 2016 SP1 On-Premise CRM App for Outlook

(2) ShareShare
ReportReport
Posted on by Community Member

Hi, 

1.  Using CRM 2016 SP1 on-Premise with Exchange 2013 On-Premise

2.  The CRM App for Outlook Link is present under settings

3.  I can see eligable users and I have added the app and says app is installed for Outlook.  Both in OWA and Outlook when I go to manage apps its not listed at all.  

What can I do to troubleshoot this, its a confusing one to fix with the lack of documentation for on-premise.

    I had the same issue.

    In my case the server profile was configured with a delegation user.

    The app was being deployed to the delegation user instead of the user that was selected.

    I created a non-delegating server profile, modified the mailbox to store the user's credentials, and then redeployed the app.

    Once the deploy finished the app appeared in the OWA apps list.

    My problem now is that the app seems to be having authentication issues.

    I suspect a new SPN may be necessary to support the OAuth2 flow but I haven't had a chance to dig in to the issue.

    Any ideas?

    Hi Scott, you are dead on.  Changing the email profile to use stored user credentials and then manually updating each users mailbox to store the password gets the app deployed.  I actually opened a ticket with MS and they are getting the same auth problem we are.  I ran a fiddler capture with the HTTPS enabled and they are looking it.  Supposedly a hotfix is coming so nothing to do right now, hope that saves you any future hassle until that comes out.  Ill post back when they chat me.

    Paul, have you received any fresh information from MS on this?

    Thank you both!  I've been banging my head against a wall.

    In regards to the authentication "issue", are you talking in regards to iexplorer.exe prompt for credentials?

    Currently running CRM 2016 on prem, Exchange 2016 on prem, Outlook 2016 but I need to run outlook as administrator for the outlook app to function. Have either of you experienced this problem?

    If I don't run as admin, after the ADFS login I receive an error in outlook which says:

    Having trouble signing in?

    Check to see if your browser's pop-up blocker is blocking the sign in screen. If it is, choose to allow this pop-up and try again.

    If you're still having trouble signing in, try adding the following URLs to your Trusted Sites.

    It seems the only way around is to run as admin.
