Reading Outook emails - Reply fails with outlook App

Hello All - The outlook integration works perfectly fine in machine when I run the bot; now the solution wr have to deploy in a server from where we are having issues.

In VM we installed Mail App (Outlook trail version) where we configured the mail id as TEST@outlook.com
with this - we are using exchange email activity which reads the mails but while replying to that email it fails (stating some error where we dont have access may be due to trail version).

I would like to know when we deploy the bot in VM how that BOT can connect to email account to read the mails? do we need to have outlook (purchased ) into that VM?

the error:Source: Send Exchange Mail Message

Message: An internal server error occurred. The operation failed., WASCL UserAction verdict is not None. Actual verdict is Suspend, ShowTierUpgrade.
