      I also tried the below code,

       

       

      IMessageActivity forwardedMessage = activity;
foreach (var attachment in activity.Attachments)
{
if (attachment.ContentType.StartsWith("image/"))
{
forwardedMessage = Activity.CreateMessageActivity();
forwardedMessage.Attachments = new List<Attachment> { attachment };
forwardedMessage.ApplyConversationReference(recipient);
}
}

       

       

       and send the message activity using connector client. Got the same image invalid in recipient teams bot 

       

       

       

      Also tried to access the content url we are getting in the activity attachment , but it shows the below authorization error message 

       

      {"message":"Authorization has been denied for this request."}

       

      We are trying to send message from teams bot personal chat to the teams groups chat.

       

      Image was getting received at group chat side when manually edited the attachment conent url with a jpeg image .

        Lakshmi_145 -Could you please try the below code for image attachment-
        Also refer the sample -Microsoft-Teams-Samples/samples/bot-file-upload/csharp/Bots/TeamsFileUploadBot.cs at main · OfficeDev/Microsoft-Teams-Samples (github.com) 

        private async Task ProcessInlineImage(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
{
var attachment = turnContext.Activity.Attachments[0];
var client = _clientFactory.CreateClient();

// Get Bot's access token to fetch inline image.
var token = await new MicrosoftAppCredentials(microsoftAppId, microsoftAppPassword).GetTokenAsync();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
var responseMessage = await client.GetAsync(attachment.ContentUrl);

// Save the inline image to Files directory.
var filePath = Path.Combine("Files", "ImageFromUser.png");
using (var fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.None))
{
await responseMessage.Content.CopyToAsync(fileStream);
}

// Create reply with image.
var reply = MessageFactory.Text($"Attachment of {attachment.ContentType} type and size of {responseMessage.Content.Headers.ContentLength} bytes received.");
reply.Attachments = new List<Attachment>() { GetInlineAttachment() };
await turnContext.SendActivityAsync(reply, cancellationToken);
}

private static Attachment GetInlineAttachment()
{
var imagePath = Path.Combine("Files", "ImageFromUser.png");
var imageData = Convert.ToBase64String(File.ReadAllBytes(imagePath));

return new Attachment
{
Name = @"ImageFromUser.png",
ContentType = "image/png",
ContentUrl = $"data&colon;image/png;base64,{imageData}",
};
}
