[quote user="bfluet"]The hierarch.om file contains entries for each folder listed in the folder window. A directory attached as a mailbox has an entry that looks like this:
0,0,"KLY2EVRG:2CB3:FOL01D7F","71D72317:c:\\temp\\testmail","testmail"
You can see how changing the directory name or location would make the entry invalid. [/quote]
Just for the reference of anyone later who might come along reading this thread seeking information, I think that is like an entry for a folder in an external Mail Box not an entry for the external Mail Box itself. This is what a Mail Box entry looks like:
0,0,"01131047:G:\\PMBoxOldMail:NEW","01131047:G:\\PMBoxOldMail",Name_Unavailable
This is what a tray looks like.
1,2,"15921048:People","01131047:G:\\PMBoxOldMail","People"
An external Mail Box entry seems like it will stick around in the hierarch.pm file forever, even if it is obsolete. There apparently is no way to ever get rid of it or change it once it has been created. Folder entries and tray entries may be eliminated from the hierach.pm file when they are removed within Pegasus.
