Send a mail using the current outlook user account without to provide credentials with PowerShell

In this post I will show you how to send a mail using the current outlook user account without to provide credentials.

Context

- You want to send a mail from the user device

- For instance to send logs without user interaction

- You don't want to provide credentials

- You don't want to provide server info

- Mail should be sent if outlook is opened or not

The solution

We will use a well known solution.

Indeed you can use COM objects with Office components like Word, Excel, Outlook, as below:

There will be a workaround depending if outlook is opened or not, we will see that.

Now let's see a mail in the below cases:

- If Outlook is closed

- If Outlook is already opened and user by the user

For both solution we will use below template:

- Dest mail: damien.vanrobaeys@gmail.components

- Subject: "Hello from $User_Name on device $Computer_Name"

- Body: "Hello from $User_Name on device $Computer_Name"

See below the code:

Error: Retrieving the COM class factory

You can have the below issue when you use the create the ComObject Outlook.Application

In my case this was because outlook was already opened, and the COM object can not be created.

In this case, we will use the second solution.

Outlook is closed

We will proceed as below:

1. Create the COM object

2. Create the mail

3. Assign destination mail to the mail

4. Assign subject to the mail

5. Assign body to the mail

6. Send the mail

Outlook is opened

We will proceed as below:

1. Use the opened Outlook object

2. Create the mail

3. Assign destination mail to the mail

4. Assign subject to the mail

5. Assign body to the mail

6. Send the mail

7. Close outlook
