# Outlook Mobile Signature

Installation guide for Outlook on iPhone and Android

This guide is intended for users who wish to benefit from their **Signitic signature on Outlook mobile**, whether on iOS or Android.

> **Warning:** The management of **Internal/External** conditions is not yet supported.

🔄 The functionality is identical on both platforms.

The most important thing is to meet the prerequisites:

-   Have Outlook 365 in order for portability on your iOS/Android smartphone: version 17.3 minimum
    
-   The Outlook application must be updated for the signature to appear. (Latest possible update, remember to check your mobile stores to be sure).

-   It is important that the address connected to Signitic is the main account on the Outlook application on your mobile device.
    

If the prerequisites are met, simply open a new message on your smartphone and wait a few seconds for the signature to appear.

## ⚠ **Known issue on smartphone add-ins**

In some cases, certain users may not have their signature appear instantly.

In this case, it is necessary to activate the Signitic add-in in the list on your smartphones. Here is the procedure to follow:

-   Open Outlook on the smartphone, then go to the application settings.

-   Open the "Add-ons" option.

-   In the list, look for Signitic and then check the box on the right. If this action has already been performed, uncheck the box and repeat the process.

🕓 If this does not resolve the issue, it is most likely a **deployment delay** on Microsoft's side. The signature will eventually appear automatically.
