Upgrade to 2017 Causes Email issues:
5 out of 5 upgrades to Sage CRM 2017R3 from Sage CRM v7.3SP3 this fall/winter have resulted in the same issue for our clients. They send an email from CRM and receive the typical "There was an error sending your email, your email was not sent. Please consult your system administrator". The interesting thing is the email does get sent. However it does not show up under the communications.
I've called Tech Support and never gotten anywhere with this. There are no changes to email server or other email setting changes. I realize at this point I should be asking about 2018 but I don't want to move anyone to 2018 until we can figure out why this happens with every 2017 upgrade. What did we miss in the upgrade notes? Is anyone else experiencing this? We need to get this resolved for our customers and are unsure of what to fix.
