Lotus Error Message for Local Mail File Authorization

I got a Lotus error message that says, ‘You are not authorized to the database for user's local mail file'.
The message came from my local mail files. It was received four times. I already tried to delete the local replica and even created it twice for backup. The process was long and tedious. But still it doesn’t work.
I use Lotus client 6.5.5 with StdR7Mail Version 6.5.3. Template.
What can I do to prevent the error?
