Issue with Office365 Send Email (V2) connector in Power Apps Code App (Invalid Recipients + Connection Duplication)

[Ayoubbendbyagc]

Hi everyone,

I’m facing an issue while using the Office365 – Send email (V2) connector in a Power Apps Code App developed and deployed using PAC CLI.

Context :

Power Apps code app

Email sent via Office365 Send Email (V2) connector

Connection defined explicitly in the power config JSON (shared connection ID specified)

Problem :

Even though the recipient email address is valid, the flow fails with the following error:

{
"status": 400,
"message": "One or more recipients are invalid.",
"error": {
"code": "ErrorInvalidRecipients",
"originalMessage": "At least one recipient is not valid., A message can't be sent because it contains no recipients."
},
"source": "office365-ne.azconn-ne-003.p.azurewebsites.net"
}

Payload used :
{
"emailMessage": {
"To": "my.email@company.com",
"Subject": "Test Email",
"Body": "Email sent by Power Apps",
"Importance": "Normal"
}
}

The email address is correct and works in other apps / flows.

No dynamic value or empty variable is involved.

🔹 Additional Issue (Possibly Related)

Despite explicitly defining the shared Office365 Outlook connection ID in the power.config.json, the app keeps creating a new Outlook connection at runtime instead of reusing the existing one.

This makes me wonder if:

The connector is not resolving the connection properly

The payload is being altered / not passed as expected

Or the connection context is not correctly bound in code apps

Any guidance or workaround would be highly appreciated.

Thanks in advance 🙏
