How to update contact information in Exchange Online in Microsoft 365
This article describes how administrators and users can update personal contact information by using the Exchange admin center in Microsoft 365. It also discusses how administrators can limit the kind of contact information that users can update.
Administrators and users can update the following personal contact information by using the Exchange admin center:
- First name
- Last name
- Display name
- ZIP/ Postal code
- Work phone
- Home phone
- Mobile number
Only managed users can update their personal contact information. Users who are in organizations that use directory synchronization can't update their contact information by using the Exchange admin center. For organizations that use directory synchronization, use on-premises tools to update contact information.
