Importing Mailboxes !

get a copy of exmerge.exe, from there it is simple run exmerge save data or move it to were the new server can access it and then run exmerge on the new server. Exmerge creates .pst files for each mailbox selected, it won't create the mailboxes on the new server but will import the items to each folder.

Hope that helps

Use tools Directory Export, pick the Containers you want to export and set the filename and path this saves out a Comma Separated Value file, You may then have to open the CSV as a spreadsheet and edit the X400 column to suit the new server name\Organisation\site etc, You can also edit the names and directory names if you need to. You can then use Directory Import on the new server to create all the mailboxes before using Exmerge to fill them , If you have altered the Directory names in the CSVyou will have to rename the PST files to match as Exmerge takes the directory name from the export server to use as the PST name then tries to match PST to Directory name on the import server.
Couple of points to note;
If you have edited tne CSV file you will have to open it in a text editor and add a to the end of the file otherwise the last item will not import. The other point is that extra SMTP addresses (alias names) are not exported, These have to be added manually to the new server.
