Error: Send Outlook Mail Message timed out

[Maria_Carlao (Maria Carlão)]

Hi guys,

I am testing action center with a simple workflow that sends an email at the end of the process. When running the workflow via UiPath Studio it runs successfully. Although, when running via Orchestrator, it sends the following error message:

The operation has timed out.

RemoteException wrapping System.TimeoutException: The operation has timed out.
at UiPath.Mail.Activities.SendMailActivity.EndExecute(AsyncCodeActivityContext context, IAsyncResult result)

I think you should check if on PC on which you launching the process is open port for sending emails (default for o365 is 25)

When running the workflow via UiPath Studio it runs successfully. Although, when running via Orchestrator, it sends the following error message:

You mean getting error when running in Unattended mode ? If yes I guess Outlook is not opened that time because of that it is getting failed.

Please make sure Outlook application is installed and in Available while running the process.

Hi @lakshman and @pikorpa
Thanks for your answers

To answer your question, @lakshman, yes, I’m running in Unattended mode.

When running other processes on the same environment and the same machine, the activity Send Outlook Mail Message works fine. The problem is in this workflow

Can you please check if outlook is perfectly on that system or not ?

It’s weird. Can you put Send Outlook Mail Message activity inside Retry Scope activity and mention retry number as 3.

Check below post for your reference

The operation has timed out in send outlook message

hi @Linto Just change value to by Outlook Exe path to Default Value into Registry. Computer\HKEY_CLASSES_ROOT\WOW6432Node\CLSID{0006F03A-0000-0000-C000-000000000046}\LocalServer32 Also check if you have 2 version of Outlook installed in your system. please go below path and delete version which you do not required. Computer\HKEY_CLASSES_ROOT\TypeLib{0006F062-0000-0000-C000-000000000046}\1.2\0 delete Win32 or Win64 as per your version value set for first path.

Hope this may help you

Thanks

Hello @Maria_Carlao

have you tried to record the process? Turn on Enable recording in the process settings (Prchestrator). This way you’ll know the issue. Usually it’s due to Outlook not opening properly. I’ve resolved this kind of issue by opening Outlook app first and then sending a message.

To be honest Outlook app is generally not a recommended way to manipulate emails. It’s not stable usually and generates a lot of issues. Do you have a possibility to use Office365 API? Azure App Registration would be needed.

Best,

Artur

Send SMTP Email is much simpler and more reliable, and doesn’t require Outlook to be open nor even installed. Just a suggestion.

it is
