Hi @Robert60 - Similar symptoms don’t necessarily indicate the same underlying cause.
I see you have already reached out to our VIP Support, but providing more details can help us find a solution faster.
First off, are you seeing the empty emails yourself or only your recipients?
There was recently an MS Outlook bug that made the message code invalid and when you replied to the email, it was shown as blank in the Outlook app.
We have made a workaround in a recent update that will fix the code when replying, so on new replies the issue won’t happen again.
Make sure to install version 10.4.5642 or newer to get that update. If you’re not getting the patch when you “Check for update” inside the app, you can install it manually here: https://www.emclient.com/dist/latest/setup.msi
