This permission can be assigned in a specificenCommunityServer 2008.5 SP2 (Build: 40407.4157)http://msmvps.com/blogs/andersonpatricio/archive/2008/02/04/microsoft-transporter-suite-for-internet-mailboxes-configuring-exchange-impersonate-permission-in-exchange-server-2007.aspx#1547945Wed, 19 Mar 2008 21:34:00 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1547945SP<p>Sylvain, if you have not yet figured out the error, try this:</p> <p>Add this value to your web.config file in IIS for your OWA site (make sure to create a backup file before you change it)</p> <p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&lt;httpRuntime maxRequestLength=&quot;10000&quot; /&gt;</p> <p>Enter this string right under the &lt;system.web&gt; line. The 100000 denotes the size limit of e-mail messages to import (in KB I think).

BUT I still have a problem: it seems that transporter is not able to migrate bigger mails than 1.5Mb. Anyone has found a workaround for that?</p> <p>Thanks!</p> <div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=1542697" width="1" height="1">http://msmvps.com/blogs/andersonpatricio/archive/2008/02/04/microsoft-transporter-suite-for-internet-mailboxes-configuring-exchange-impersonate-permission-in-exchange-server-2007.aspx#1541940Thu, 13 Mar 2008 13:28:08 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1541940Sylvain<p>Ok, thanks for that. It&#39;s working now for me. However I still have a problem using transporter. I have about 4000 Imap mailboxes to move to my exchange2k7, but don&#39;t know how to give a root login/pwd to my get-imapmailboxdata cmdlets to be able to open each source mailbox without having to know each user&#39;s pwd!</p> <div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=1541940" width="1" height="1">http://msmvps.com/blogs/andersonpatricio/archive/2008/02/04/microsoft-transporter-suite-for-internet-mailboxes-configuring-exchange-impersonate-permission-in-exchange-server-2007.aspx#1524375Mon, 25 Feb 2008 21:38:55 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1524375Matthew Trotter<p>Thanks for the post. They don&#39;t really make it completely clear that you HAVE to do this. I think alot of assumptions that the Exchange Admin should just be able to do this create alot of confusion, especially for people used to the EX2K3 Mig Wizard.</p> <div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=1524375" width="1" height="1">http://msmvps.com/blogs/andersonpatricio/archive/2008/02/04/microsoft-transporter-suite-for-internet-mailboxes-configuring-exchange-impersonate-permission-in-exchange-server-2007.aspx#1504751Sat, 09 Feb 2008 12:34:58 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1504751subject: exchange<p>Business Email System Penetration Varies Greatly by Customer Size, Industry and More, says Ferris Research</p> <img src="http://msmvps.com/aggbug.aspx?PostID=1504751" width="1" height="1">http://msmvps.com/blogs/andersonpatricio/archive/2008/02/04/microsoft-transporter-suite-for-internet-mailboxes-configuring-exchange-impersonate-permission-in-exchange-server-2007.aspx#1504749Sat, 09 Feb 2008 12:32:17 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1504749subject: exchange<p>Business Email System Penetration Varies Greatly by Customer Size, Industry and More, says Ferris Research</p> <img src="http://msmvps.com/aggbug.aspx?PostID=1504749" width="1" height="1">
