This is the error i am getting while i run the project.

For Each Email: Could not load file or assembly ‘System.Linq.Async, Version=5.0.0.0, Culture=neutral, PublicKeyToken=94bc3704cddfc263’. The system cannot find the file specified.

It seems that you have some issues with downloading all required dependencies from external feeds for the UiPath.Mail.Activities or UiPath.MicrosoftOffice365.Activities package version that you are trying to use.

Check if you have this feed https://pkgs.dev.azure.com/uipath/Public.Feeds/_packaging/UiPath-Official/nuget/v3/index.json in Manage Packages and if is accesible.

I’m having the same issue and this didn’t help, the url already listed, tried to remove the email package and add it again also didn’t help

Provide the UiPath Diagnostic Tool logs for the Activities Issue or raise a support ticket.

Hii @marian.platonov

I did not install the Microsoft365 package as it was not mentioned in the tutorial. Once I installed and ran the project. it works well.

Thanks you
