I have an app that has worked for a long time. Now all of the sudden it is failing to deliver to a Microsoft address that I don't have in the list of emails. I keep the list of emails in an Excel sheet and they are pulled into the app based on a dropdown selection as well as a people picker combobox. It is adding the email address microsoft@powerapps.com into my list. Not at the beginning or end but in between other emails. Here is what happens when the button is selected.
Mail.SendEmailV3(DataCardValue59.Text&","&Concat(DataCardValue35.SelectedItems,Mail&","),DataCardValue21.Text,HtmlText1.HtmlText,true,{filenames:DataCardValue26.Selected.Result&DataCardValue27.Selected.Result&DataCardValue28.Selected.Area&Now()&".jpeg",files:UploadedImage1.Image}))
And a couple days later I get an email that says the message was undeliverable because of the recipient microsoft@powerapps.com. It shows the email addresses and it shows this microsoft email as the second in line.
Anybody have any ideas why this is happening?
