To achieve this setup add this to the notesdtapp ini
[General] ArchiveDest=<ValidKeyword>
Specifies the destination for migrated archives. Valid values are "PST" or "server."
If ArchiveDest=server, then the ArchiveDestServerArchive parameter (documented separately below) determines whether archives will be migrated to users' server-mail mailboxes or personal-archive mailboxes.
[General] ArchiveDestServerArchive=<#>
For Exchange 2010 and Office 365 (only), and when migrating to users' Exchange server (only), this parameter determines whether archives will be migrated to users' server-mail mailboxes (0) or personal-archive mailboxes (1). For example:
ArchiveDestServerArchive=1
… tells the wizard to migrate users' archives to their personal archive mailboxes. Note that this ArchiveDestServerArchive parameter is relevant only if ArchiveDest=server (as documented above). If ArchiveDest=pst, or if you are migrating to Exchange 2007, this ArchiveDestServerArchive parameter is ignored.
