Hi
Welcome to UiPath forum
If it’s a outlook account and if it’s configured in your machine where the bot is running then we can use GET OUTLOOK MAIL ACTIVITY and SEND OUTLOOK MAIL ACTIVITY
which is way more easier to use
Did we try with that
And even if the outlook application is not configured in your machine then you can try with GET EXCHANGE MAIL activity and SEND EXCHANGE MAIL activity where we need to pass the outlook credentials alone
For details on what properties to mention in exchange activity
Here you go
