Hi @Fifer, Jake ,
We understand that you would like to merge your MCPID to your Outlook account, and it may not be related to Outlook client. Due to here we mainly focus on general issues about Outlook Desktop client and know little about MCPID, we may not be able to provide you with more professional solutions. According to my research, I found a similar thread which mentioned how to merge a MCP account onto a personal Microsoft Account, for you reference, you can refer to this link: Merge my MCID onto a personal Microsoft Account.
If it's invalid or you still need more help, it’s suggested to post a new thread in this forum:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thanks for your understanding and hope your question will be resolved soon.
