Outlook Troubleshooting

• Confirmed both New Outlook and Classic Outlook were present.
• Determined CapstoneEmail relies on Outlook COM automation, which is supported by Classic Outlook.

Resolution

1. Opened Control Panel > Mail.
2. Created a new Outlook profile.
3. Set the newly created profile as the default profile.
4. Uninstalled New Outlook.
5. Set Classic Outlook as the default mail application.
6. Opened Classic Outlook and confirmed mailbox functionality.
7. Retested CapstoneEmail.

Result

CapstoneEmail successfully generated emails.

Root Cause

Likely caused by a corrupted or misconfigured Outlook profile and/or conflict between New Outlook and Classic Outlook COM integration. Capstone Email requires Classic Outlook COM automation and functioned normally after establishing a new default Outlook profile and removing New Outlook.
