Local Outlook in virtual environment crash when we add long path attachment

Question

We have MS Office 2007 install localy on our Windows 2008 R2 server with App-V SP3 client. We have configured Outlook to start in the Acrobat Reader XI virtual environment for the pdf file preview. When we try to add a long path attachment in Outlook,
Outlook crash.
If we run Outlook outside the Reader virtual environment, Outlook does not crash. If i try to make a procmon to find a solution, Outlook freeze but does not crash and procmon does not return interresting information. I have try to start Outlook in another
virtual environment, it still crash.
We have made some more testing. We have discovered that Outlook crash on file path longer than 242 character. Normally, the max path in Windows is 260 character. Thats why we does not  understand why we have this bug.
Any idea someone to solved this problem?

Answer 1

The path of the file we try to add to the mail is something like this : 
G:\Urbanisme\Volet Réglementation\Certificats de conformité\Conformité - Environnement_MDDELCC (LQE)\2015\LQEnv_Carré Belvédère-Gestion Élias_milieux humides_2015-02-27.gaegra\LQenv_projet de développement _ Carré Belvédère_2015-03-23_marjac.docx
I am not sure about the Q drive you talk about... I know than in App-V 4, there was Q drive, but we use App-V 5 SP3 (i forgot to tell in my original post).
Thanks for your help Rorymon!
