My setup: Home user, Intel Gen12, Windows11 Pro. My Outlook is configured for local storage (POP3). No Sharepoint, no Microsoft Teams, not linked to my iPhone. Very simple setup that I have used for years, apart from having auto update enabled in Windows.
I am trying to load an alternate older .pst file that is stored locally on the same HDD. I go to File, Account settings, and try to load the required .pst. I get the error message, "You cannot use an Internet address here. Enter a path that points to a location on your computer or on the network." This happens as I try to browse to a local file. As soon as I try to access my D: data drive I get the nonsensical error. It is not an internet address.
