We are running GP2015R2. Have been for less than a year. We would like to start utilizing email out of GP. But there is the pesky message when clicking on Company Emil Setup;
Running Windows 10, with MSOutlook 2013 set as the default in Settings as the mail client. I find set up screen for various messages. But I do not find a broader setting for GP2015R2 being able to email out.
Few questions to help assess this issue:
1. Is this a 64 or 32 but install of office?
2. What mail setting has been selected in the System Preferences form? Exchange or MAPI?
3. Are you using GP in a terminal server environment?
4. Have you selected a default mail PROFILE on the machine?
Knowing this information will help to provide a solution to your problem.
