Last update: 2022-11-08



Mbox call fires, but the MbocPcId is not written when moving from one domain to another.


  • Adobe Target implemented for two domains using DTM
  • Cross-domain tracking is enabled
  • 1st and 3rd party cookies set in the Adobe Target UI


Steps to resolve/Workaround

  • Check for third party cookies on the website
  • MboxPC will be saved on ‘’ domain in a cross-domain scenario
  • MboxPC should be set in the third party cookies
