Hello MK-02040430-0,

You're encountering a very specific and frustrating error: AADSTS7000112: Application '2f29638c-34d4-4cf2-a16a-7caf612cee15'(Microsoft Dynamics CRM for Microsoft Office Outlook) is disabled. This error directly points to the legacy Dynamics 365 for Outlook add-in being disabled in your Azure Active Directory (AAD).

Here's a breakdown of the problem and potential solutions, along with why Microsoft Support might be delayed:

Understanding the Problem:

Dynamics 365 for Outlook (Legacy):
- The application ID 2f29638c-34d4-4cf2-a16a-7caf612cee15 corresponds to the legacy Dynamics 365 for Outlook add-in.
- This add-in is being phased out in favor of the Dynamics 365 App for Outlook.

AADSTS7000112 Error:
- This AAD error indicates that the application is disabled in your Azure Active Directory tenant.
- This means that users are prevented from authenticating with the add-in.

Why It Might Be Disabled:
- Accidental Disablement: An administrator might have accidentally disabled the application.
- Security Policies: Your organization's security policies might have disabled the application.
- Microsoft Deprecation: Microsoft might have disabled the application in your tenant as part of the deprecation process.

Troubleshooting and Solutions:

Verify Application Status in Azure AD:
- Azure Portal:
  - Log in to the Azure portal with an administrator account.
  - Navigate to Azure Active Directory > Enterprise applications.
  - Search for the application with the ID 2f29638c-34d4-4cf2-a16a-7caf612cee15 (or "Microsoft Dynamics CRM for Microsoft Office Outlook").
  - Check the application's status. If it's disabled, enable it.
- PowerShell:
  - You can also use PowerShell to check and enable the application.
  - Use the Get-AzureADServicePrincipal and Set-AzureADServicePrincipal cmdlets.

Check Conditional Access Policies:
- Azure Portal:
  - Navigate to Azure Active Directory > Security > Conditional Access.
  - Check for any Conditional Access policies that might be blocking access to the Dynamics 365 for Outlook add-in.
- It is very possible that a conditional access policy is blocking the old application.

Encourage Transition to Dynamics 365 App for Outlook:
- Dynamics 365 App for Outlook:
  - The Dynamics 365 App for Outlook is the recommended replacement for the legacy add-in.
  - It offers improved performance, reliability, and functionality.
  - It is also much more secure.
- User Training:
  - Provide training to your users on how to use the Dynamics 365 App for Outlook.

Microsoft Support (Escalate):
- Escalate Your Ticket:
  - Since you've already opened a support ticket, escalate it.
  - Provide them with the error message and the application ID.
  - Emphasize the urgency of the issue.
- Microsoft Documentation:
  - Point them to the Microsoft documentation that explains the deprecation of the old outlook add in.

Check Exchange Online Configuration:
- In some rare cases the problem can be related to the exchange online configuration.

Why Microsoft Support Might Be Delayed:

Deprecation Focus: Microsoft's support resources are likely focused on the Dynamics 365 App for Outlook, as the legacy add-in is being phased out.
Complex Issue: The issue might require coordination between multiple teams (Dynamics 365, Azure AD, Exchange Online), which can lead to delays.
High Volume: Microsoft Support might be experiencing a high volume of tickets.

Key Recommendations:

Prioritize transitioning to the Dynamics 365 App for Outlook.
Verify the application status in Azure AD.
Escalate your support ticket if you don't receive a response soon.

By following these steps, you should be able to resolve the issue or find a suitable workaround.
