Hi @mitesh_parmar,

Select All Packages in package manager and search for your Mail. Activity then download it.


i did,but still show same error.
does it because of Uipath 2018.4.2?

No,right now we don’t see any issue with this version.

For now create a new project and try it once.

Let me know if it works…
