Using New Outlook on Windows for personal email, calendar, and contact management
In Outlook (including new Outlook for Windows), the order of email accounts in the left folder pane is controlled by the folder arrangement, not by an explicit “account order” setting. Accounts and their folders can be reordered by customizing the folder pane.
In new Outlook for Windows:
- Go to Mail.
- On the ribbon, select the View tab.
- Select Folder pane, then choose Custom folder order.
- In the folder list, select and hold the account or folder you want to move, then drag and drop it to the desired position.
- Alternatively, right‑click the folder and choose Move up or Move down.
If the folders have been rearranged and need to be reset alphabetically instead of custom order:
- On the View tab, select Sort Folders (or Folder pane depending on client).
- Choose Order folders A to Z.
- To go back to a custom order later, re‑select Custom folder order from the Folder pane dropdown.
Note: Some special folders such as Search, Shared with me, and In-place archive cannot be moved and always appear at the end of the account’s folder list.
