Done.
Now what?

Check, test mail?

Re ran the wizard.
Hopefully things are OK now…

Test email says it was sent OK and was received.

Strange…

Glad it’s working, please update me if something changed.

Hi,

I have been trying to troubleshoot this email issue too, and we use Office365. This cropped up around March 7 or so. Any guidance would be helpful!

Thanks,

Jason
