the path is not wrong. The syntax is usually used for long path or unicode characters.
Do you use Outlook 365 or 2016?
Which version are you using (sub-version 1702 ?)?

Unfortunatelly C# doenst play well with long path syntax.

Thank you in advance!

I couldnt reproduce the usage of long path syntax.
Could you tell me the exact version and language of your Office?
Maybe this would help to narrow down the circumstances.

Meanwhile you can use the todays released version 1.7 which will work with long path syntax.

I am in the island of Reunion, my language is the French
I downloaded version 1.7 it works for now ... but the path is still weird \? \ C: \ Users \ xxxx

Hello Gorgio,
thanks for your information.
Maybe the desktop version of office in Office 365 is different to the standalone version.
The path looks weird but dont worry.
The notation with \?\ is a valid path for windows. It is just not very common and
some programs and environments like C# dont support it.

I already got a screenshot from another guy with the same issue.

I am glad it works now.

Hello Thomas
A big thank you for your answer
As you say the bottom line is that it now works with version 1.7
I will inform you if necessary.
Well, the hello of the Indian Ocean
