I have setup the system and it seems to be working.... however i frequently get this message appear in the alerts section of the admin console..... try as i might i cant figure out what service is using the network service? i created a new user and all the services appear to running using it (i checked to make sure the appropriate security in exchange for that account is correct)

I ran the archiver against an account with 1.2gb of mail and asked it to archive mail older than 12 months... it only seemed to archive about 50MB which is surprising low... makes me wonder if it able to archive the attachments correctly?

Any help would be appreciated.

The 2 messages i get are:

  • Hi,

    This is a known issue - it's a slight race condition when you leave the Admin Console open at the same time as messages are being indexed.

    It's currently set to be fixed in the next release, but shouldn't actually cause you any problems apart from the slightly strange error messages.

    Many thanks,
