Hi @phearin ,
Does the "To" ComboBox connect to a Person column in your SP List?
Do you want to generate your email content automatically based on the selected option within the ComboBox, the Title Text Input value, and Details Text Input Box?
I have made a test on my side, please consider try the following workaround:



Set the OnSelect property of the "Send Email" button to following:
Microsoft365Outlook.SendEmailV2(
ComboBox1.Selected.Email,
SubjectBox.Text,
"Dear " & ComboBox1.Selected.DisplayName & ", <br/>" & RichTextEditor1.HtmlText
)
If you want to select multiple person in your "To" ComboBox, please modify above formula as below:
Microsoft365Outlook.SendEmailV2(
Concat(ComboBox1.SelectedItems, Email & ";"),
SubjectBox.Text,
"Dear " & Left(
Concat(ComboBox1.SelectedItems, Email & "&"),
Len(Concat(ComboBox1.SelectedItems, Email & "&"))-1
) & ", <br/>" & RichTextEditor1.HtmlText
)
Please try above solution, hope it could solve your problem.
Regards,
