Exchange 2013 mailbox auditing command with showdetails parameter in ps1 script is not working via task scheduler

Question

 
Hi All ,
In my environment we are having exchange 2013 enterprise edition with SP1 which is installed in windows server 2012 standard edition.
We have enabled mailbox auditing for few mailboxes and also we have made simple powershell script with only the below mentioned commands .when i run the  ps1 script  in exchange management shell ,i can able to get the relevant output.
CMDLETS in powershell script :
Search-MailboxAuditLog -StartDate ((Get-Date).AddHours(-24)) -EndDate (Get-Date) -showdetails | fl >e:\output.txt
Note : we are having only the above commands in ps1 script , apart from that we don't have anything in it .
Sametime i have scheduled the same powershell script via task scheduler .But i cannot able to get the valid output ,instead of that i was getting a blank output file with no data in it . 
Steps handled on my side to run the powershell script in task scheduler: 
1.when i remove the parameter showdetails in the ps1 script ,i can able to get the output in the txt file .But in my scenario showdetails is the only parameter which will brought me more and in depth details about mailbox auditing.
The Difference what i have seen between exchange 2010 and exchange 2013 
when in run the same powershell script via task scheduler in exchange 2010 enterprise environment installed in windows server 2008 r2 enterprise OS, i can able able to get the proper output without removing the showdetails parameter .
I am using the below methods to run the ps1 file via task scheduler in exchange 2013 environment .
program/script : C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Add arguments : -PSConsoleFile "E:\Program Files\Microsoft\Exchange Server\V15\Bin\exshell.psc1" -Command ". 'C:\scripts\MailboxAuditReport\test.ps1'"
I have mentioned the error below and that is the one what i have faced, when i try to run the PS1 script directly in windows powershell and not in exchange management shell .
Error message : "the requesting account does not have permission to access the audit log"
Please help me out to resolve this case .
Thanks
