Hi @Jessica_Moseley ,
Thanks for your reply!
If you are using the community version, then I strongly suggest to get the latest version.
New release means that sometimes some bugs are found and fixed
If you are using an enterprise version and, if I was in your place then I would directly contact the UiPath Support (Link). As you can see, there are some similar topics here (e.g. https://forum.uipath.com/t/mail-save-attachments-activity-do-not-work/84979 or https://forum.uipath.com/t/outlook-attachments-not-found/283228), with unfortunately no resolution …
Best regards,
Marius
