# [Engage] Synchronization issue with an Outlook address

Are you encountering an error message when attempting to synchronize your Outlook address? Indeed, following Microsoft's security updates,...

## Why is my connection no longer working?

Are you encountering an error message when attempting to synchronize your Outlook address? Indeed, following Microsoft’s security updates, personal Outlook accounts can no longer connect via IMAP/SMTP using a simple email and password.

Engage can therefore now only support secure (OAuth) connection for Microsoft 365 business accounts.

##   
Does this affect me?

If you use a personal Outlook account (@outlook.com, @hotmail.com, @live.com), and if your address is already synchronized in Engage and is working, nothing changes for the moment.

However, you will be affected by this update if:

-   you log out
    
-   you change the password of the mailbox.
    
-   the connection expires
    
-   You need to reconnect your address.
    

In these cases, the standard email + password connection will no longer work.

## What are the alternatives?

As of today, there is no solution to connect a personal Outlook account via IMAP/SMTP in Engage.

Possible alternatives:

-   Use a Microsoft 365 business account
    
-   Set up a new synchronization to a compatible address (Gmail, ... )
    
-   Use another email address compatible with IMAP/SMTP (OAuth)
    
-   Migrate to a Microsoft 365 business account
