Failed to Merge

[Dina_Otero]

I tried merging two contacts in Marketo and I received the following System Error: Failed to merge leads [144111]

Anyone know what this means?

Support may know.

usually when a merge error occurs it is because Marketo cannot merge the records in the CRM.

Hi Dina,

I actually did a write-up of this very issue for someone else a few days ago; I hope this helps you out.

Thanks Courtney! The duplicate was never added to Salesforce (dupe blocker) so I wanted to merge them to update the existing lead record with the history. I've done this before so I don't know what else is causing the error. I opened a case with support so stay tuned.
