A rose by any other name, would smell just as sweet.

OMC, OMESC, OMESQ, 42tools...We can certainly understand if you are confused. For an extended period of time we called our company OMC. OMC is an acronym for "Open Messaging and Collaboration", at the time the company slogan. Now, "omc.com" is unfortunately taken and although not active obviously not for sale.
After trying out a couple of names we could match with a good domain name we ended up with 42tools, and we plan to stick with this name for a while.
The name aside, the company is the same and we still strive to provide the the best open source connector for exchange.
