Dear @Wiesen, Noli S
There are several places Outlook uses to store contacts. Your personal contacts are stored in folders either in an Outlook Data file or in your Exchange or Microsoft 365 mailbox. You can add, edit, or delete contacts stored in your personal contacts folders. For more information, please refer to Create, edit, or delete a contact list (or contact group) in Outlook and Delete a contact in Outlook for Windows
In New Outlook > Select People on the left of the window > Select the contact or contact list that you want to delete, then click Delete on the Ribbon, and select Delete.
On the other hand, organizational contacts are stored in a Global Address List. You can't add, edit, or delete contacts stored in the Global Address List. In that case, any remove (X) option you see may not be saved because only the list owner or an administrator can make changes. Therefore, please contact your administrator for assistance with Global Address List contacts. For reference: Address lists in Exchange Online and Remove a global address list in Exchange Online
Moreover, to help narrow this down, could you tell me:
- Are you using Outlook on the web, New Outlook, or Classic Outlook?
- Is this your own personal contact list, or a shared/company distribution list?
- After clicking the X to remove a contact, do you receive any error message, or do the names simply reappear later? A screenshot of the page where you see the "X" buttons but no Save option would also be helpful (remember to remove your personal information before sharing, such as the email address or full name).
I hope the information shared is helpful. If you have any questions, please feel free to reach out. I'm looking forward to your update.
