Help Disable SMS Sync to Owa?

[recDNA]

I made the mistake of setting up sms sync to my work owa account. I desperately need to shut it off. Every sms goes to my work email owa app as well as my sms app on the phone. I went in owa and disabled email sync. Owa says it is shut off. But sms still goes to owa. I even deleted the microsoft exchange account syncing to work email so I no longer get work email. Synced to phone but sms still somehow goes to owa. Microsoft couldn't help. Verizon couldn't help. Anybody been through this?
