Changing the default data file in outlook 2019 error
My default data file account is set to outlook account but when I want to set the gmail account, I get the following error "The selected outlook data file (.pst) format cannot be used. Outlook data files (.pst) must use the same format as .....". I have already the followed the method in https://docs.microsoft.com/en-us/answers/questions/69776/outlook-2019-default-data-file-error-pstost.html I tried removing the data file account, but it doesn't allow me because it's set as the default account and I get the following error - "The default data file cannot be removed.". The plan was to remove the data file and then add again with unchecking the "use cached option" from the control panel. Any solution for change the default data file would be appreciated. Thanks.
