Set up file action - Email - Exchange Online (Microsoft 365)

You can use the Email file action to exchange files with email. This topic explains how to set up a file action to send or receive files using Exchange Online (Microsoft 365).
If the direction is:

Source, before the message is run, the defined email account inbox is searched for applicable emails. If found, the attached files of these emails are saved to the Working folder.
Target, after the message is run, an email is created using the defined email account, the created file in the Working folder is attached to the email, and the email is sent. The original file stays in the Working folder. If you want to zip the file before sending it by email, do a Zip file action previously to the Email file action. In this case the zipped file is attached to the email.

Note
You can set up file actions for these connector types:
Azure file storage
Azure File Storage (API)
Azure Blob storage
SharePoint
Before you set up this file action, make sure:
An Azure AD app registration exists for the target Microsoft 365 tenant.
The app registration has the required Exchange Online permissions, granted and admin-consented. For more information, refer to Microsoft Learn. For example, Overview of Microsoft Graph permissions.
A secret reference exists for the app registration's client secret.

Steps

Click Connectivity studio - Integration Design.
Click the Connectors tab.
In the list, find and select the desired connector.
Click Edit.
You can export connectivity setup and import it in another D365 F&SCM environment. For example, you first set up and test the connectivity setup in a development environment. When finished, you deploy the setup in your production environment.
To prevent messing up your production data, use different file locations for your development or testing environment and for your production environment.
To strictly distinguish between different environments, you can define unique file action properties for each of your environment types. So, each file action can have a different set of properties for each applicable environment type.
Which file action properties are applicable to the current environment is defined in the Environment type field on the Connectivity studio parameters.
Example: If set to Development, the file action properties, as defined for environment type Development are applicable.
In the Environment types field, select an option.
Note
For each file action, you can repeat the sub-tasks for each of your environment types. To set the environment-specific properties of a file action, only change the environment type, find the file action, and set the properties. So, do not create a new file action for each environment type.
Expand the File action section.
