exchange

I recently had the fun of recovering an Exchange server which had run out of disk space and "stopped working". I'm not sure exactly what they did before passing it on to me, but at that point the databases were not mounting. They had two databases, "Mailbox Database.edb" about 9GB and "Public Folder Database.edb" about 9MB, Both in the "First Storage Group". A little more investigation and a bit of eseutil /mh showed that both databases were in the Dirty Shutdown state and there were logfiles missing. Interesting.

For quite a few monitoring tools (i.e. VMware vCenter), there aren't any options for mail authentication. To get around this on your Exchange server, you'll need to do the following:

Open the Exchange Management Shell are run the following:
> New-ReceiveConnector -Name "Anonymous Relay" -Usage Custom -PermissionGroups AnonymousUsers -Bindings [serverip]:25 -RemoteIpRanges [ranges]
> Get-ReceiveConnector "Anonymous Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"
