Help

Hello, I’m trying to send an email using the Send Outlook Mail Message activity, however every time I run it, varying errors. This is one of them:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.SystemException: Creating an instance of the COM component with CLSID {0006F03A-0000-0000-C000-000000000046} from the IClassFactory failed due to the following error: 8001010a The message filter indicated that the application is busy.

Welcome to the Uipath Community.

Is outlook application installed in that machine ? And also is it in Online ?

Run Uipath studio as Administrator and then try once.

Hi, Outlook is installed in the machine, and yes it is online. I’ve successfully retrieve multiple emails before but I can’t seem to send one. I tried running Uipath as Administrator. There’s another error:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.Runtime.InteropServices.COMException: The operation failed.  The messaging interfaces have returned an unknown error. If the problem persists, restart Outlook. The operation failed. An object cannot be found.

I tried running it again and there’s another error:

Are you using Enterprise or Community Edition of UIpath ?

If you are using Enterprise Edition then contact uipath support team and show these logs and they will help you better in this.

Alright, thank you.

I think I’ve figured it out. I’m not sure if the SentOnBehalfOfName property accepts just any kind of string but I tried removing the string I placed there, waited a few seconds, ran the workflow, and then it worked.
