Okay. I think I know what the problem is.
I've to the CTP V2 version installed on my workstation. If I test it on my Exchange server I get the same error. I think the V2 is letting me do date/time calcs that V1 doesn't allow. ________________________________ From: Miller Bonnie L.

And, it's forcing me to learn a little more about powershell-my knowledge is still greatly limited by what I've actually used thus far. So, I added my servername and changed the outfile to a path that exists (D:\foldername\something.csv), and saved as a .ps1 file. In the Exchange mgmt shell, when I run the ps1 file, I get the following: [PS] c:\myprompt>c:\scripts\getexternalmailstats.ps1 Cannot convert value "7/24/2008 10:15:49 AM" to type "System.Decimal". Error: " Invalid cast from 'DateTime' to 'Decimal'." At C:\scripts\getexternalmailstats.ps1:5 char:22 + $rundate = $($today - <<<< 1d).toshortdatestring() You cannot call a method on a null-valued expression. At C:\batch\plscriptlibrary\getexternalmailstats.ps1:5 char:44 + $rundate = $($today - 1d).toshortdatestring( <<<< ) Any ideas? I'm barely deciphering what you've written at the moment =) Thanks, Bonnie From: Campbell, Rob [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2008 9:18 AM To: MS-Exchange Admin Issues Subject: RE: Inbound/Outbound Mail Stats I hacked this out of a script I already had written. If you schedule this to run once a day, it should accumulate the internet email stats from the previous day to a .csv file. You'll need to change the $ht variable to the name of your server. You can go back farther than one day to back fill by manipulating the $rundate variable. $today - 1d will get the stats from yesterday. If you change it to $today -2d it will get the stats from the day before yesterday, etc. within the limit of your message tracking log retention. It has to run on an E2K7 server, or a workstation with the Exchange Management Shell installed. If you want to use it with SCCM you can modify it to write an event to the application event log with the data, and have SCCM pick up and report on that event. $today = get-date $ht = "server name here" $headings = '"Date","Sent","Send MB","Received","Receive MB"' $rundate = $($today - 1d).toshortdatestring() $outfile = "internet_email_stats.csv" if (!(test-path $outfile)){ac $outfile $headings} $recv_recs = get-messagetrackinglog -Server $ht -EventID "RECEIVE" -Start "$rundate 12:01:00 AM" -End "$rundate 11:59:59 PM" -resultsize unlimited $smtp_recvs = $recv_recs |? {$_.source -eq "SMTP"} $send_recs = get-messagetrackinglog -Server $ht -EventID "SEND" -Start "$rundate 12:01:00 AM" -End "$rundate 11:59:59 PM" -resultsize unlimited $smtp_sends = $send_recs |? {$_.source -eq "SMTP"} foreach ($smtp_recv in $smtp_recvs){$bytes_recv += $smtp_recv.totalbytes} foreach ($smtp_send in $smtp_sends){$bytes_sent += $smtp_send.totalbytes} $mbytes_recv = $bytes_recv/1mb $mbytes_sent = $bytes_sent/1mb $outstr = $rundate + "," + $smtp_sends.count + "," + $mbytes_sent + "," + $smtp_recvs.count + "," + $mbytes_recv ac $outfile $outstr ________________________________ From: Miller Bonnie L. [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2008 7:29 AM To: MS-Exchange Admin Issues Subject: Inbound/Outbound Mail Stats Exchange 2007 SP1, one server with all roles. What is the best way to get numbers that show our average inbound (received)/outbound (sent) mail stats per day? We are looking for numbers of messages that travel to/from the Internet. We do not currently have anything like MOM nor SCCM, but will be bringing in SCCM at some point if that could help. If there are specific performance counters to track, that works for me-just don't know which ones to look at. If Exchange already stores this data somewhere and I just need to pull it, even better.
