Exchange App: getting unknown domain
I've installed the Splunk for Exchange app. One of the issues I'm having is with users showing up with @unknown.
I've created the domain_aliases.csv on the search head, with UNKNOWN, unknown, and our netbios name, and our domain name. But it's still showing mlanghorst@unknown.
I have 2 indexers and one search head. I've thought that maybe this needs to go on the indexer, but according to the docs I should only need to install the TA* apps there.
What am I missing here? Not sure yet what records that this search is keying off of.

I have the same issue as OP. Was there a resolution to this? My NetBios names are not being translated to the domain and I have my domain_aliases.csv file in the "local" folder of the Exchange app on my Search Head. The format of my CSV file is similar that of OP.
Thanks.

Hey DavidTS,
You are not having the same problem as OP as the fix suggested repaired his problem. Open up a new question and don't forget to include your Splunk version, Exchange app version, OS version and a copy of your domain_aliases.csv file!

Let's say you had a domain "SPLUNK" which is really "splunk.com", then your domain_aliases.csv file would look like this:
UNKNOWN,splunk.com
SPLUNK,splunk.com
If you have
UNKNOWN,unknown
SPLUNK,splunk.com
then you would see what you are seeing.

UNKNOWN,caiso.com
unknown,caiso.com
ISOOA1,caiso.com
I put the lower case unknown in there after UNKNOWN didn't work. ISOOA1 is our netbios name. Yet they're still showing up as mlanghorst@unknown.
