Hi,

I am currently in trial mode and doing some email sending with a test domain. It is a hosted on MS 365

I believe I have everything setup correctly but I am receiving this error when sending from an outside address

Any ideas on what may be wrong

  • I have checked all settings and they seem to be correct.

    I raised a case with Support ( 05598010 ) on the 12th but haven't heard anything yet.

    My concern is that the license for our legacy SEA appliances is going to expire in a few days, so I need this working asap.

    I seem to recall that there is a 2 week grace period for the license expiration.

    Can anyone confirm this ?
