"Fetch new mail" do not work

hote

When I click "Fetch new mail"in the email page, the following message display:

Error retrieving mail from 商务邮箱的管理员邮箱(means Administrator's mailbox of Business mailbox): Error retrieving message: [Ljava.lang.Object; cannot be cast to com.atlassian.confluence.content.CustomContentEntityObject

After this error happened,I can just view and delete the old emails,but not get new ones.

what's more,I checked the pop configuration,it works well“Connection test successful.”

Could you tell me how to resolve this?

Hi He Teng,

You didn't say which mail server you are using or which version of Confluence, but searching your error message brought up this bug which affects Lotus Domino and Dovecot mail servers that are connected to Confluence 4.2.x, as discussed in this bug report: https://jira.atlassian.com/browse/CONF-26036

If this is the case then the solution appears to be to allow the mail-user to delete emails from the mail database and the issue will disappear, as described in this knowledge base article on the subject: https://confluence.atlassian.com/pages/viewpage.action?pageId=296093924

If this isn't the cause of your issue then please open a ticket with Atlassian Support so that we can investigate this issue further and update the knowledge base article for this error with other possible causes and solutions.

All the best,
John
