I just installed D365 on premise and am having trouble getting users set up for the App for Outlook. I can push the app to them, have set up Server Side Synch (hybrid Dynamics on premise and Exchange Online) and their mailboxes successfully configured, but when they try to use the App for Outlook they can't. They get repeatedly asked for their credentials, then just get an error. Does anyone know why this is and how to resolve it? This is on the latest version of Dynamics and Version 1708 build 8431.2236 for Outlook. The issue happens with both the Outlook App and Outlook online.
The possible reason for this issue could be that:
Cause 1: Microsoft Dynamics 365 App for Outlook was unable to connect to the authorization service to ensure that you are authorized to use this app.
Cause 2: This can occur if your Dynamics 365 (online) URL was changed after the Dynamics 365 App for Outlook was installed. For example: If your Dynamics 365 URL was contosocorp.crm.dynamics.com when you deployed the app but you later changed the URL to contoso.crm.dynamics.com.
The resolutions are as below.
Resolution 1: Please close the app, and open it again. If the problem persists try closing your internet browser and reopening it again. If the problem continues, try again at a later date.
Resolution 2: If you changed your Dynamics 365 (online) URL after Microsoft Dynamics 365 App for Outlook was installed, you need to redeploy the app:
1. A user with the System Administrator role can redeploy the app to users by opening the Dynamics 365 web application and then navigating to the Dynamics 365 App for Outlook area within Settings.
2. Select the users who should have the app redeployed and use one of the Add App buttons to redeploy the app.
3. After the Status changes to "Added to Outlook", you can verify if the issue has been resolved. If you already had the app open, close and reopen it.
Hope it helps.
Thank you for your reply! I have tried on multiple browsers, on multiple days with no luck. I also have not changed to URL for our IFD since installing the app, and I have tried redeploying the app - also with no luck. So unfortunately, I don't think these strategies will resolve my issue.
Many thanks for your update.
What is the version number for your Dynamics 365? If you use 8.2.2, have you applied UR2 release?
We are using version 188.8.131.52 on premise. Is there a later update we should be on to solve this issue?
First, you should update D365 to 184.108.40.206 version.
Then you should be able to get Browser to work by performing the following:
Protected Mode is enabled for Internet security zone. To enable Protected Mode: in IE11, •go to Tools > Internet options > Security tab > Internet.
Protected Mode is enabled for Local intranet security zone. To enable Protected Mode: in IE11,•go to Tools > Internet options > Security tab > Local Internet.
Protected Mode is enabled for Trusted Site security zone. To enable Protected Mode: in IE11,•go to Tools > Internet options > Security tab > Trusted Site.
Now, there's a bug in App for Outlook for Outlook client (desktop client). Microsoft is working on the hotfix but has not bee released yet. It is fixed for D365 Online but not for On-Premise. I'm still waiting for Microsoft to release the official update.
I have some updates on this:
I have updated to 220.127.116.11 and was still having the issue, even using protected mode. I opened a Microsoft Support ticket and they had a patch for the system, but even after that it did not work! We are still working on resolving the issue. As far as I can tell it is working for everyone except Hybrid connections from on premise Dynamics and Exchange Online. I will try to update this post when we do get a resolution.
Thanks for your reply,
Microsoft Support got this resolved! Our main issue was that we had a different version of AD FS than the instructions were written for. In addition to the AD FS Powershell command the system gave us we needed to use the following command:
Grant-AdfsApplicationPermission -AllowAllRegisteredClients -ServerRoleIdentifier "https://auth.'OurOrganization'.com/"
We also needed to tweak our IIS settings, which were as follows when it worked:
Anonymous Authentication Enabled
ASP.NET Impersonation Disabled
Forms Authentication Disabled
Windows Authentication Disabled
Microsoft Dynamics CRM (Site)
Windows Authentication Enabled
ASP.NET Impersonation Enabled
XRMServices > 2011
XRMServices > 2011 > Organization.svc
Stern, were you able to get App for Outlook working on the Outlook Client (desktop client)?
Yes, it is working online and through the desktop application
