Thank you kindly for the response and direction! <img width="19" height="19" border="0" src="http://community.pmail.com/emoticons/emotion-1.gif">

<p>I have a client with a WinPmail client.  With an IMAP account they were connected to a remote office and server.  The remote office closed its doors and shipped the mercury - mail folder. </p><p>I installed a mercury server and created the user....then copied the contents of the original mercury mail directory for that user to the new directory that was created for them.  I configured the pegasus client to connect via imap.</p><p> </p><p>I can see the few pieces of email that were at the root of the users box from the week the folder was shut down.  However there are no subfolders (where the user used to have hundreds)  In this mercury/mail folder is a imc-3e8 folder (cache folder)</p><p> </p><center style="font-size: 13.3333px;"><h2>Files used for IMAP cache</h2></center><p style="font-size: 13.3333px;"></p><table border="1" width="90%" bgcolor="#FFFF80" align="center"><tbody><tr valign="top"><td width="20%"><b>Filename or extension</b></td><td width="15%"><b>Version information</b></td><td><b>Information</b></td></tr><tr valign="top"><td>IMC*</td><td><i>WinPMail v4.21+</i></td><td>For each IMAP directory a cache directory is created.

<p>Pegasus Mail cache files are created and used locally by Pegasus, not server-side by Mercury.</p><p>In the server mailbox there should be files with extensions .CNM (messages), .PMM, .PMI, .PNM (folders) as well as a HIERARCH.PM file to define the folder structure.</p><p> </p>

Thanks for the quick response Rolf.  So, is there any way to remount this cache so the user could see it again?  Even when I create a new user with the same name in pmail and then copy the contents of this mail users folder over, I still only see the root directory items and there are no subfolders at all that show up.  

<p>Try posting in the Pegasus Community Support forum, hopefully someone there knows more about how the Pegasus cache works than I do!</p><p> </p>
