unified ID

Unifying or merging multiple Microsoft support or subscription IDs into a single ID cannot be done directly through documentation or self-service tools in the provided context. This type of account/ID consolidation requires Microsoft support intervention and identity/ownership verification.

To proceed, contact Microsoft support for the MSN Partner Hub / account area and request that the three IDs be reviewed and consolidated so that only MS0991179855 remains active. Provide:

1. All three IDs:
   • MS0991179855 (to keep)
   • MS0994628103
   • MS0992956276
2. Proof of ownership/association for each ID (business details, contact info, etc.).
3. A clear request that any active services, permissions, or associations under MS0994628103 and MS0992956276 be moved to MS0991179855, and that the other IDs then be closed/retired.

If access to the account or admin portal is blocked (for example, due to MFA or sign-in issues), the pattern in similar cases is that support escalates to the Microsoft Data Protection team, who can verify identity and perform tenant/account-level changes after additional checks.

Because this is an account- and identity-level operation, only Microsoft support can complete it; there is no PowerShell, portal, or configuration option in the context that will unify these IDs directly.
