Linking Activation - Dynamic Tag Management (DTM) account to Marketing Cloud

After the accounts are linked, DTM can be accessed by clicking 'Activation' in the left side menu.

If you receive one of the following errors when linking the account, contact support. 

• “ERROR Your account cannot be linked because it is not assigned to a company”.
• “ERROR Your account could not be linked: Your Adobe ID user is already linked to this company with the legacy user.”     
• “ERROR An unexpected error occurred while linking your account.”
• “ERROR Your account could not be linked: Your company is not yet enabled for the Marketing Cloud. You may request access here. Error: Organization missing."

If the company has already been provisioned for the Marketing Cloud, the error is a provisioning issue. For resolution to any of errors listed above, contact support. In the request include the Account Name, Marketing Cloud user name, DTM user name, and the error you are receiving.

If the company has not been provisioned for the Marketing Cloud, follow the instructions here.
