Connect Microsoft 365 (1-Click) - eCards

Send eCards cards from your Microsoft 365 business email address using secure 1-click OAuth - no SMTP passwords or app passwords required.

Overview

If your organisation uses Microsoft 365 (formerly Office 365) - for example yourname@yourcompany.com on Microsoft's platform - you can connect it to eCards via 1-click OAuth. Cards will be sent directly from your business Microsoft 365 email address.

[!NOTE]

This uses Microsoft's secure OAuth 2.0 flow. eCards never stores your password - only an encrypted access token.

Prerequisites

Before connecting, make sure:

You have a Microsoft 365 business account (e.g. yourname@yourcompany.com)
Your Microsoft 365 Admin has allowed OAuth app consent (or has pre-approved eCards)
Pop-ups are allowed in your browser for eCards
SMTP AUTH is enabled for your mailbox (see Admin Configuration below)

[!WARNING]

Microsoft 365 organisations often restrict third-party app access and disable SMTP AUTH by default. Both may need to be enabled by your admin before connecting.

Step 1: Go to Email Settings

Log in to eCards
Go to Settings -> Email Accounts

Step 2: Connect Your Microsoft 365 Account

Scroll to the One-Click OAuth Connections section
Click Connect Outlook
In the popup, sign in with your Microsoft 365 email (e.g. yourname@yourcompany.com)
Review the requested permissions and click Accept

[!WARNING]

eCards requests the https://outlook.office.com/SMTP.Send scope. This is the Microsoft-approved permission for sending emails via SMTP OAuth2. eCards does not read, delete, or access your inbox.

Step 3: Confirm the Connection

The popup closes automatically and your Microsoft 365 email will appear under Connected OAuth Accounts with a Microsoft badge.

Step 4: Send a Card

All cards you send will automatically use your Microsoft 365 address as the From address - for both instant and scheduled sends.

Microsoft 365 Admin Configuration

1. Enable SMTP AUTH for the mailbox

By default, Microsoft 365 may have SMTP AUTH disabled. Your admin needs to enable it:

Go to Microsoft 365 Admin Center
Navigate to Users -> Active users
Select the user whose mailbox you want to connect
Click Mail tab -> Manage email apps
Enable Authenticated SMTP
Click Save changes

If your organisation has disabled user consent for third-party apps:

Go to Azure Active Directory Admin Center
Navigate to Enterprise Applications -> Consent and permissions
Under User consent settings, allow users to consent to apps, or pre-approve eCards as an admin
Alternatively, grant tenant-wide admin consent for eCards' app registration

Contact your eCards account manager for the Application (Client) ID needed for admin consent.

***

Disconnecting

Go to Settings -> Email Accounts
Find your Microsoft 365 account under Connected OAuth Accounts
Click Disconnect

Cards will fall back to the default eCards sending address.

Troubleshooting

I see 'Need admin approval' on the Microsoft sign-in screen

Your Microsoft 365 organisation has restricted third-party app consent. Your IT admin needs to either enable user consent or grant admin consent for eCards. See the Admin Configuration section above.

Connection succeeds but sending fails with an authentication error

SMTP AUTH may be disabled for your mailbox. Ask your Microsoft 365 admin to enable Authenticated SMTP for your user account in the Microsoft 365 Admin Center.

The popup shows a white screen or does not close

Allow pop-ups for eCards in your browser. In Chrome: address bar -> lock icon -> Site settings -> Pop-ups -> Allow.

Cards are still sent from eCards' default address after connecting

Disconnect and reconnect to issue a fresh token. If the issue persists, contact support.
