ERROR Send Email Desktop Version

Posted on by Paabl00

Hello everyone,
I recently changed the password for my Power Automate user account, regenerated the connections, and everything, but one of the actions is giving me an error.

It's the action of sending an email, and this has been happening since the Desktop version.

I've attached the error message:

----------------------------------
An exception occurred in the invocation target: Microsoft.PowerPlatform.PowerAutomate.Desktop.Actions.SDK.ActionException: The email message could not be sent. ---> System.Reflection.TargetInvocationException: An exception occurred in the invocation target. ---> System.Runtime.InteropServices.COMException: Outlook does not recognize one of the names.

-------------------------------------

If anyone knows how to fix this, I would be very grateful.

I also tried deleting the connection and creating a new one, but that didn't work either.

Have a good day, and I look forward to your replies.

Hi there!

Here's my process to resolve:

1) delete the action.

2) save.

3) exit.

4) reopen and readd this action.

In short, the schema is not being updated. Deleting actions and re-adding typically resolves for me.

This error occurs because Outlook cannot resolve one of the recipient names passed from Power Automate Desktop.

It is typically caused by using display names instead of valid email addresses, incorrect formatting (such as commas instead of semicolons), or corrupted Outlook profile/address book after a password change.

The most reliable fix is to use full email addresses, clean input variables, and if possible switch to cloud-based email actions instead of Outlook desktop automation.

Hi, I've been getting the same error since last week.
Has anyone been able to fix it? @trice602, deleting the action didn't work for me.
