Can I remove manually messages in a mailboxes ?

I have over 38 000 messages for a user, and I want to keep only one month. If I remove them, it looks like the files store.cch, store idc and store.usr doesn't change ? Is there a command to adjust them ? Is it a problem ?ThanksKaty* Running on NMS 4.15 patch 4

Hello Katy,

Shut down all servers.

Remove all files in server-root/msg-instance/store/mboxlist.

Run stored

Run reconstruct -m to build a new mailboxes database from the contents of the spool area.

Run reconstruct -r

After reconstruct -r completes, restart the server processes.

I recommend to you you install patch 7

Bye
