Issue in retrieving Exchange mail

Help

Hi All,

We are facing the below issue while retrieving mails using ‘Get Exchange Mail Messages’ activity

Error: “The specified string is not in the form required for an e-mail address”

Note: The sender of the e-mail has an underscore “_” in their e-mail id. No other special character is used. Ex: abc_xyz@example.com

Also we have tried the same with different sender (e-mail id) without underscore “_” which works fine. Ex: abc.xyz@example.com

Please find the version details below,

Ui Path Studio version: 2018.4.1
Exchange Version: Exchange2013_SP1
Mail Package Version: 1.6.0
