Miscellaneous topics that do not fit into specific categories.
Hi Ellie,
If you are referring to the order of the actual email accounts in the left-hand folder pane of new Outlook, unfortunately they cannot currently be manually reordered. The custom folder order option only changes folders within an account, not the position of the accounts themselves.
The Favorites workaround also does not change the account order, so if that is what you are trying to achieve, you have not missed a setting. You can submit this as a feature request through Help > Feedback in new Outlook.
If you are using classic Outlook instead, please let me know, as the options are different there.
Thank you, and feel free to respond back for more assistance.
