# 📋 Outlook Add-In (classic): Attaching files (two methods)

This article explains the two methods you can use to attach files to your email via the Outlook Add-In and send them securely with FTAPI.

## Attaching files to emails and sending them with FTAPI

To attach files to an email for sending with FTAPI, you have two different options available:

1\. Use the **paperclip** icon or the **drag and drop** function as usual. There are two things to keep in mind here:

-   With this option, you are bound by the size restrictions imposed by your Outlook (e.g., max. file size 20 MB)
-   To send the email and the attachment securely, you must click on “**Send with FTAPI**”, otherwise Outlook will not know whether FTAPI should be used or not.

2\. Use the selection from the FTAPI Outlook Add-In “**Attach files**”.

-   This option is primarily used when you want to bypass the size restrictions for attached files.
-   With this option, all attached files are automatically encrypted and stored on the server before being sent.
