I recently started using Outlook 2016 for my email. I have AT&T and Outlook.com mail accounts that I want to access in Outlook on my desktop. Like some other users, my C: drive is a SSD with limited space and I want the Outlook data files to reside in an "Outlook" folder on my D: drive. I followed your instructions in the thread "Hot to move IMPA data files" when I created my initial Outlook account for my AT&T email account. Adding the "ForcePSTPath" in the registry yielded success with the Outlook data file being located in the correct folder on the D: drive. However, when I add my Outlook.com account, the corresponding data file is created on the C: drive. I understood your instructions that any accounts added AFTER the "ForcePSTPath" registry entry would default to the identified drive, but it does not. I am hoping that you might be able to shed some light on what I might be doing incorrectly.
