Some emails in Archive missing

As usual doing the archive, the emails will go over to the archive database.

When going into the archive database, the emails are missing. Some folders in archive also not found.

I have checked all of the archive database, none with the emails. They have gone missing.

Need help, what should I do?

Subject: restore, check settings, and test

Hopefully you have a good backup to restore the messages from. If not, setting up your backups is a higher priority than fixing archiving.

Check the client/user/mailfile archive settings and any policy that would apply to the user. Perhaps some types of messages are being excluded or moved to a different archive file.

Test from the client with fake messages. Archiving is using the local machine RAM to copy/paste messages as a batch from one db to another. If you run out of local RAM, the client can lock up and the messages that haven’t been pasted are lost.
