Question details

Users need alternative methods to access or synchronize Microsoft 365 emails within Gmail due to authentication compatibility issues.

Product
Microsoft 365 and Gmail
Device & OS
not provided
Scenario
Attempting to connect a Microsoft 365 mailbox to a Gmail account for unified email access and management.
Observed behavior
Direct connection via POP or IMAP fails because Gmail may not fully support the modern authentication protocols strictly required by Microsoft 365.
Before you start

Before attempting any workarounds, verify with your Microsoft 365 administrator that your organization permits POP/IMAP protocols, external email synchronization, and third-party app access.

Solution 1Recommended

Use an Email Client with Modern Authentication

The recommended long-term option is to switch from Gmail to a dedicated client that natively supports Microsoft modern authentication.

Because Microsoft enforces modern authentication for security, using an officially supported email application ensures complete synchronization without connection drops or compromised security.

1
Install a Supported App

Download the official Microsoft Outlook app or a modern client like Apple Mail from your device's respective app store.

2
Add Your Account

Open the application, navigate to 'Add Account', and select 'Microsoft 365' or 'Exchange' from the list of email providers.

3
Authenticate Securely

Enter your email address and follow the Microsoft web-based login prompt to securely complete the modern authentication process.

Frequently Asked Questions

Why does Microsoft 365 no longer work with standard POP/IMAP in Gmail?

Microsoft has deprecated basic authentication to enhance security, mandating modern authentication (OAuth2). If an email application like Gmail attempts to connect using legacy basic authentication, Microsoft 365 will reject the connection.

Can I simply forward my Microsoft 365 emails to Gmail instead?

Yes, you can configure automatic email forwarding in the Outlook Web App settings. However, this is only possible if your Microsoft 365 IT administrator permits automatic forwarding to external domains.

Does Gmailify keep all my custom Outlook folders synchronized?

No. While Gmailify merges your inbox and applies Gmail's spam filters to your Microsoft 365 emails, it does not act as a full two-way synchronization service for custom folders or subfolders.
