I recently updated my legal name from Sakshi Singh to Sakshi. I am trying to ensure that this change

For Microsoft services, name information can come from different places, so each area must be updated where it is stored.

1. Microsoft account (personal / home use)
   • Update the display name on the Microsoft account used for Windows, Outlook.com, Microsoft 365 Family/Personal, etc.
   • Sign in to the Microsoft account profile and change the display name from "Sakshi Singh" to "Sakshi". It can take up to 24 hours for this to appear everywhere (Windows profile, Outlook sender name, etc.).
   • If the name still appears incorrectly after 24 hours, sign out of apps and Windows devices using that account and sign back in so they refresh the profile data.
2. Work or school (Microsoft 365 organization / corporate systems)
   • If any of the systems showing the old name are work or school accounts (for example, Microsoft 365 Apps, Outlook with an organization email, Teams), the name may be controlled by IT or HR.
   • In that case, contact the organization’s IT admin or HR and request that the account’s name be updated to "Sakshi" in the directory. Some organizations do not allow users to change their own names.
   • After the admin updates the name, allow up to 24 hours for the change to propagate across Outlook, Teams, and other Microsoft 365 services.
3. Microsoft Learn / certifications (if applicable)
   • For Microsoft Learn profile display name (public profile, certificates, transcripts): open the profile menu on Microsoft Learn → Settings → under "Personal info, username, and URL" update the display name to "Sakshi" and save.
   • For certification/credential legal name issues (for example, exam registration name mismatch), use the dedicated credentials support channel to request a correction to the legal name.
4. Local Windows account name (if used)
   • If a local Windows account (not a Microsoft account) still shows the old name, change the local account display name through Windows account settings as documented in the user account name guidance.
5. Profile data coming from other systems
   • In some apps (for example, Outlook mobile contact cards or organizational address books), name and title may be pulled from HR or directory systems that are not directly editable by the user. In these cases, contact the relevant department or admin and ask them to update the source record to "Sakshi".
6. Allow for propagation and sync
   • After each change, wait up to 24 hours for the new name to appear consistently.
   • If a specific Microsoft 365 service still shows the old name after that time and the source system is correct, contact Microsoft Support from the account/billing support page for further assistance.
