# How to update the Outlook Signitic add-in

Update the add-in for optimal use of your email signatures.

> **Error:** To ensure the proper functioning of Signitic on Outlook, it is essential to perform the latest [add-in update](https://admin.microsoft.com/Adminportal/Home#/Settings/IntegratedApps/:/Redirect/Store/WA200003499/fr-FR).
> Please note, this action must be performed only by the Microsoft 365 account administrator.

## Why update the add-in?

Our technical teams have developed a more powerful add-in to enable you to better manage the integration of your email signatures on Outlook!  
  
Here are the changes :

-   Increased performance
    
-   Change of sender email
    
-   Improved random rotation of your campaigns with each insertion of your signatures
    
-   Optimized deployment: instantaneous for web and 24 to 48 hours for Outlook heavy client
    

> **Info:** Add-in deployments carried out after July 30, 2025 already have the new version; no update is required.

## How to update the add-in?

1.  To take advantage of the new add-in, go to the [Microsoft admin manager](https://admin.microsoft.com/Adminportal/Home#/Settings/IntegratedApps/:/Redirect/Store/WA200003499/fr-FR)

> **Info:** It is possible to experience a delay of 24 to 48 hours for the add-in to be up to date.

### How can I check if I already have the new update?

If you do not see a message indicating that an update is available, we recommend checking by clicking in the add-in menu.  
  
If the status is OK but there is an action “Update the add-in”, this means that you are not using the latest version.

A request for a link to a manifest file indicates that the current version of your add-in does not support the new update.
