I received an email from my boss telling the sentence: "Try outlook resources inc DBA Company Name". I am not sure what it means, what I asked him was to confirm a number account that he gave me wrong.
Ok, following your comments about "outlook resources inc" being the name of the company, clears this up a little. In the USA this would more conventionally be written "Outlook Resources, Inc" - capitalizing the first letter of each word, and a comma between the name and the fact that it is "Incorporated". The fact that it was not written like this made it harder for me to understand.
DBA as you suspected, does not mean Database Administrator, it means "Doing Business As". As I'm sure you know, the official company name and its "brand name" may be very different.
So this sentence means ... try this company name, giving you both the official legal name, as well as the name that it trades under and is generally better known by.
