Handling multiple advertising accounts efficiently within a single interface
Hi Maxichar74,
Thank you for reaching out to Microsoft Advertising support! I understand you’re experiencing issues when setting up sub-accounts under your manager shell.
If you are looking to manage other advertiser’s accounts, the best way to set this up would be to link the customer’s account to your manager account.
When linking to another customer’s account, you gain access and control over that Microsoft Advertising account as a direct manager. Direct managers can run campaigns, take over billing and payment responsibilities, granting and removing account access by managing link request, and other account management activities. For more information on how to link accounts, please click here.
I hope this information was helpful!
Sincerely,
