Configure Office365 Permissions for the Salesforce Inbox App

Publish Date: Nov 19, 2025
Description

Note: This information applies to legacy versions of Salesforce Inbox for Outlook and Gmail and the standalone app Salesforce Inbox for iOS and Android.

Salesforce Inbox requires permission via an OAuth flow to access a users Office365 email inbox. If the Office365 Users can consent to apps accessing company data on their behalf setting is set to No, non-admin users are blocked from connecting their Office365 email account to a connected app via the OAuth flow.


When you try to connect to an Office365 account in Salesforce Inbox without admin permissions, you will receive the following error indicating you need admin approval.

'Need admin approval. Salesforce Inbox needs permission to access resources in your organization that only an admin can grant. Please ask an admin to grant permission to this app before you can use it.'
 
Resolution

Set Up Office365 for Admin Consent

To provide a more streamlined authorization flow, provide admin consent to Salesforce Inbox.

Note: To learn more about admin consent, see the Microsoft Documentation.

You can set the Users can consent to apps accessing company data on their behalf setting to Yes, and any users accessing Salesforce Inbox receive a normal accept prompt when logging in to the app. However, that setting applies globally to all your apps set up with Office 365.

Instead, grant permissions once for all of your users accessing Salesforce Inbox, without changing the setting globally for all your apps.

1. Navigate to this URL. 
2. Log in to your Office365 account. A window to grant consent appears.
3. Click Accept to grant admin consent permissions to Salesforce Inbox on behalf of your organization.

Any subsequent attempts from non-admin users to log in to Salesforce Inbox are presented with a normal login flow.
