Workmail domain verification Route53 failed

Hi AWS,

I am trying to set up Workmail for my domain, hosted in Route53. I have checked a couple of times but somehow the records in Workmail failed, though I checked and double checked with the record in Route53. It may be that the recards in Route53 open and close with " automatically. However, some records that do that did got accepted, so I figured that connot be the issue. Could you direct me to a resolution?

Thanks!
