vCenter Server 6.7 does not send email alerts to multiple recipients when scheduling tasks

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:
Using VCSA 6.7 HTML5 interface, if you schedule a task through the UI, you can set an email recipient to be notified when the task is complete. The task dialog states that you can specify multiple recipients by entering them in the format "[email protected];[email protected]" (semicolon-separated list).

However, if you use semicolons to separate multiple addresses, a notification will not be sent when the task completes.

Environment

• VMware vCenter Server 6.7.x

Resolution

To resolve the problem, use commas instead of semicolons to separate the addresses.

Example : "[email protected],[email protected]"
