Issues with Outreacher Lindy Not Connecting to Outlook Properly

Hello All, Anyone's help would be much appreciated- we are having issues with our Outreacher Lindy- whether we use the outreacher template or try to build our own outreach Lindy, Lindy won't seem to connect to my outlook properly. Rather than sending from my personal work email, connected via outlook, the sender is showing as "outlook_988ABE4DD19F689@outlook.com". Does anyone know how to solve this? This sender name obviously looks very spammy and will tank our email campaigns. Thank you!!
