Using classic Outlook for Windows in business environments
You are correct, I found the same:
lpe-data.errorSaveFailed when trying to add a new contact with a business address
If I only add the contact with name and email, it works.
If I then try to add a business address, it will say it was saved successfully, but if you done open the contact card again, the address is not there.
