Delete Otter Notetaker from Teams and Outlook

Hello @Oliver Gritz,

Thank you for sharing the update.  

Since Otter still appears embedded despite removing the account and app, the issue likely persists due to residual permissions and assignments in Microsoft Entra. Please follow these advanced steps to fully revoke Otter’s access: 

Step 1: Remove User Consent via Microsoft Graph PowerShell 

Before starting, install the Microsoft Graph PowerShell SDK: Install the Microsoft Graph PowerShell SDK | Microsoft Learn 

Open PowerShell and run: 

Connect-MgGraph -Scopes "Application.ReadWrite.All", "Directory.ReadWrite.All", "DelegatedPermissionGrant.ReadWrite.All", "AppRoleAssignment.ReadWrite.All" 

Get the Service Principal for Otter using its Object ID: 

$sp = Get-MgServicePrincipal -ServicePrincipalId "<objectID>"   

(Find Object ID in Microsoft Entra Admin Center > Enterprise Applications > Otter > Overview.) 

Remove all delegated permissions: 

$spOAuth2PermissionsGrants = Get-MgOauth2PermissionGrant -All | Where-Object { $_.clientId -eq $sp.Id }   
$spOAuth2PermissionsGrants | ForEach-Object {   
Remove-MgOauth2PermissionGrant -OAuth2PermissionGrantId $_.Id   
}   

Remove all application permissions: 

$spApplicationPermissions = Get-MgServicePrincipalAppRoleAssignment -ServicePrincipalId $sp.Id -All | Where-Object { $_.PrincipalType -eq "ServicePrincipal" }   
$spApplicationPermissions | ForEach-Object {   
Remove-MgServicePrincipalAppRoleAssignedTo -ServicePrincipalId $sp.Id -AppRoleAssignmentId $_.Id 

Step 2: Remove All User and Group Assignments 

$sp = Get-MgServicePrincipal -ServicePrincipalId "<objectID>" 
$spApplicationPermissions = Get-MgServicePrincipalAppRoleAssignedTo -ServicePrincipalId $sp.Id -All | Where-Object { $_.PrincipalType -eq "ServicePrincipal" } 
$spApplicationPermissions | ForEach-Object { 
    Remove-MgServicePrincipalAppRoleAssignment -ServicePrincipalId $_.PrincipalId -AppRoleAssignmentId $_.Id 

Step 3: Disable Sign-In for Otter 

In Microsoft Entra Admin Center: 

• Go to Enterprise Applications > Otter > Properties. 
• Set Enabled for users to sign in to No. 

These steps will completely revoke Otter’s permissions and prevent it from accessing Teams or Outlook.

Hello @Oliver Gritz,

Thank you for posting your question in the Microsoft Q&A Forum. 

I understand how disruptive this can be, and I’d like to help you resolve it. Please try the following steps: 

1. Disconnect Otter from Microsoft in Otter Settings 

• Log in to your Otter account at otter.ai. 
• Go to Integrations. 
• Scroll down to the Microsoft section and click Disconnect. 
• After disconnecting, check if Otter is still linked to your Teams or Outlook. 

2. If the issue persists 

At this point, we’ll need assistance from your IT administrator, as they have access to your organization’s Microsoft Entra Admin portal. Please share these steps with them: 

• Sign in to Microsoft Entra Admin Center. 
• Navigate to Users > [Select your user account] > Applications. 
• Locate the Otter application in the list. 
• Click Remove to revoke Otter’s access. 

These steps should fully disconnect Otter from your Microsoft 365 environment. If you or your IT admin encounter any difficulties during this process, please let us know, and we’ll be happy to assist further. 

Thank you for your cooperation, and I look forward to your update.
