It looks like you might have a security program that is blocking Outlook from loading the dll that it needs. Just a guess. Try with all security programs disabled, and see what happens.

Hello
Just posted the question on the Microsoft community Third party application couldn't send mail with Outlook 2013 due to Mapi failure "unspecified error"

If the value does not exist, create it: right click in that key to create DWORD value "MaximumAttachmentSize" with "5000" or run this in CMD:

reg add "HKCU\Software\Microsoft\Office\15.0\Outlook\Preferences" /v "MaximumAttachmentSize" /t "REG_DWORD" /d "5000" /f

My issue is not with Word, I can sent mail with Word.
Do you think That your code can work for another software ?

3rd party software uses settings from Windows apps, so it might. If it does not, just remove it afterwards.

What application is it actually?

I will try your code soon.
The application is "ChessBase 14"

Hello,
After some exchanges with the friendly ChessBase support and some unsuccessful tries, the solution was found, very simple !
There is an Outlook's update...

Thanks for reporting back about the solution.
So that's a good lesson for us all. Sometimes, a problem can be solved simply by updating our software. Thanks.
For most of us long-time MalwareTips forum members, updating software is such an instinctive and basic thing that we didn't even think of suggesting it...
