Troubleshooting Tips

A few issues have been reported when sending email if it is hosted in Office 365.  There are a couple of options available to resolve this.

Try this first:

Another option:

  • If, for some reason, the first option is not possible, another way might be to setup a cname record in dns such that office 365 correctly interprets the DKIM signing on our messages.  They require perfect alignment of the sender/from domain, which actually deviates from the DKIM standard itself.  This could be done by adding the following CNAME entry in the domain that the emails are coming from:
    • name: betterimpact._domainkey
    • value: appdkim.betterimpact.com
  • So, for example “betterimpact._domainkey.yourdomain.com” would point to “appdkim.betterimpact.com“.
