vCenter Appliance 6.5/6.5U1 Email Alerts Not Working
Issue
Since migrating to the new Photon OS based vCenter 6.5 VCSA Appliance, we’ve had issues with alerts not being sent to email.
As it turns out, there’s a problem with the internal configuration not being updated properly. VMware is aware of it and should hopefully fix it at some stage.
For now you can follow the workaround below.
