Office 365 (Thunderbird) - Edit/Delete a contact

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

Add personal information such as birthdate to a contact or delete a contact from your address book.

Important: The contacts you manage within Thunderbird are not saved to your Office 365 account. They can only be used within Thunderbird. Plus, any contacts you have created using a client that is connected via Exchange/Active Sync (Outlook | Apple Mail | Outlook Web App) cannot be accessed via Thunderbird.
