Hi @Didem,

Can you help us with more information.

  1. Which version of UIpath are you using.
  2. Are you using updated package for UIpath.mail.activities.
  3. What is the version of your outlook.
  4. Is it the first time you are using get outlook message activity or you have used before and it was working and now you are receiving this error.

I found this article which might help:




Using Uipath.mail.activities 1.3.0 in Uipath Studio and same in orchestrator

Outlook 2010

I´ve used it before and it works if it is less than 400 mails in inbox

Regards Didem


So you are saying because of 400 emails in your inbox folder, you are getting this exception.

Can you help us with the size of the mailbox, is any free space remaining for you.


If you manually send the email, are the emails going.

Yes, manually it works

it seems to be for Outlook 2002 we have 2010


Is your outlook application opened while using get outlook message activity, if not can you open outlook application and give a try.

Yes, it is open

It’s the same error as per this bug report:

I would try introducing some tiny delays, as it might be related to you processing the data too fast.

It’s just a guess though.
