Email messages waiting to be sent are queued in a mail queue and periodically flushed from Confluence once a minute. A Confluence administrator can also manually flush messages from the mail queue.
If there is an error sending messages, the failed email messages are sent to an error queue from which you can either try to resend them or delete them.
To view the mail queue:
- Choose the cog icon at top right of the screen, then choose Confluence Admin.
- Choose Mail Queue in the left-hand panel. This will display the email messages currently in the queue.
- Choose Flush Mail Queue to send all email messages immediately.
- Choose Error Queue to view failed email messages. You can try to Resend the messages, which will flush the mails back to the mail queue, or you can Delete them from here.
