Hi I'm still having this issue. A quick explanation is as follows: 1. If I "save an attachment to Onedrive" in Outlook.exe, the program (Outlook Microsoft 365) then my attachments are saved in the root directory of my Onedrive account. 2. If I "save an attachment to Onedrive" in Outlook.com, the website (outlook.office.com) then my attachments are saved in a subfolder 'Email attachments' on the same Onedrive account. However, both programs do link to the same file in a correct way.
