Thank you for asking this question on the **Microsoft Q&A Platform. **
There are some considerations when using service accounts:
- You can't create a service account in the built-in AADDC Users or AADDC Computers OUs.
- Instead, create a custom OU in the managed domain and then create service accounts in that custom OU.
This custom group is a group managed service account (gMSA), you can create it following these steps
Hope this helps!
