Send mail command returns error -1

[Joost Miltenburg]

LS,

A client recently ran a Windows update and since then FM returns error -1 ( unkown error ) when using the sendmail scriptstep.

I tried reïnstalling FMPro (32bit) ( can't install 64bit ), because of 32bit Outlook. That didn't help.

Any ideas?

Try;

1. Take all updates and restart

2. Reinstall FMP

3. Turn off Add ins

4. Throw out the file Msmapi32.dll and have it recreated;

• Ensure Outlook is set as the default Mail client
• Close Outlook (may have to use task manager to make sure it is closed)
• Delete Msmapi32.dll
• Run fixmapi.exe from the run prompt
• Open Outlook (Outlook will replace & register the Msmapi32.dll and then open).

5. The recent Microsoft Office 365 update to 1805 seems to have voided these fixes and created the problem in Office 365. Run this .bat as administrator to rollback to 1804. That seems to fix the Error -1 created by update 1805.
