Attendees can be invited to events via email if they don’t have a Calendar server account.
When using Mail service on the same server as Calendar service, Calendar server is already configured to send email notifications. All you have to do is turn on mail notifications and Mail service.
When an event attendee is added by email address, and the host name isn’t the same host name as on the Calendar server, Calendar server can send a message to the attendee with the event information. Also, Calendar server must have its mail account in the mail system.
Calendar server must be able to send mail to an outgoing mail server (an SMTP server) for relay, so you need the SMTP server’s host name and listening port. You must also make sure there are no firewalls blocking access to the Mail server from the Calendar server. The SMTP server must be configured to relay mail from the Calendar server as well.
Calendar server also requires access to an incoming mail server, POP or IMAP, for invitation notifications.
These instructions assume the mail servers are configured and functioning.
Important: The email account used by Calendar service should be dedicated exclusively to receiving invitations. Don’t enter your mail credentials here. When Calendar service scans the inbox, it marks all messages as “read” and deletes messages that contain an event reply.
Email notifications can only be exchanged with external users. Users with an account on your calendar server receive a standard invitation in their calendar client software.
Create an email user account in the mail system, and note the mail address, account name, and password.
For example, Calendar service could access the account calendar_server@example.com.
If you aren’t using the same server to send mail and serve calendars, get the following settings for the incoming mail server from the mail administrator:
Setting information | Example |
|---|---|
Server protocol | POP or IMAP |
Email address | calendar_server@example.com |
Host name | mail.example.com |
Listening port | 143 |
Does Mail service use SSL? | Yes or no |
User name and password | A user name like calendar_server@example.com |
If you aren’t using the same server to send mail and serve calendars, get the following settings for the outgoing (SMTP) mail server from the mail administrator:
Setting information | Example |
|---|---|
Host name | smtp.example.com |
Listening port | 25 |
Does Mail service use SSL? | Yes or no |
User name and password | A user name like calendar_server@example.com |
Required authentication method, if any | CRAM-MD5 or Kerberos |
Select the Calendar service pane, then select “Email invitations by email.”
Click Edit to configure the settings.
Enter the mail server information, then click Next.
If you’re using the same server to send mail and serve calendars, the assistant will populate with the correct information. If not, you must enter the information manually.
Click Finish.
