If you want to fix no sitemap found error in Lotus Notes, then I suggest you download SysInspire NSF to PST converter software. This tool has bulk conversion users can convert NSF files in bulk at same time. It can recover all deleted mails and convert them into PST. It has a preview option users can preview their NSF file before conversion. It has a demo version that can allow users to convert 252 items from each folder. It has technical support and all users can get help by mail or live chat. It exports all single mailbox items.
