Report Builder subscriptions - Failure writing file

Hello Everyone,

In our company we are using Report Builder to create report that its subscrubied to others as an Excel file. We are having problem when trying to run the subscription. Here is the error:

And here is the configuration:

The user that created the subscription is the same as the one that will save the file in shared location. Its an admin user so it has access to the folder and of course it has access to write data in the folder. Shared location is on the localhost where the Report Server is installed. The user is also an Active DIrectory User not local server user. When trying to run the subscripition we can see that in the mentioned error PBRS does not mention any user in the quote sings. Do we need to set up some more priviliges for this user? If yes then where? Is there a place where we can see more logs about this error?

I hope someone will help us with this problem 🙂 Greetings to you all.
