Is anyone having trouble logging onto enterprise email?

On my personal computer (with all certs installed) I haven't been able to log in to OWA for about 2 months now. I can log into just about anything with my CAC.

Can't say I've even tried in months (because I'm out, Ha Ha Ha!), but when I was in, I had issues with the new email system ever since mine migrated from the old system to enterprise email. There is a help desk number you should be able to call. Good luck.

Not to sound crazy, but what is it? I'm figuring its some type of military email. Sorry to sound ignorant.
