Exporting to multiple destination fails with "path not found" after exporting 83 files either in PDF, word or any format. the tested solutions are developed in Visual Studio 2013 C# and VB. They have been tested on sites running Windows 8.1 and 7SP1 and in all the same number of 83 document are exported before it fails.
The solution we applied: remove service pack 12 and re-install service pack 10, and it works absolutely fine and emails the documents to recipients simultaneously.
There is an issue in SP12 from my end on exporting large number of files. I have loop which loads reports(.rpt) with selection formulas and goes on up to the end generating documents to be sent as mail attachment. it has always worked before. I am wondering whether this an known issues.
