I want to import a Gmail account to a Google Apps account. I have tried the recommended method of adding a POP account. POP forwarding is enabled. I get the following message:
Server denied POP3 access for the given username and password. Server returned error: "[AUTH] Web login required: https://support.google.com/mail/bin/answer.py?answer=78754"
The username and password are NOT the issue as I am able to login to the account with the same credentials.
Is there a setting with the original account that is causing this?
First: Be sure to specify in your email client account settings the proper address, protocol, port and encryption for the connection, as instructed here: http://email.about.com/od/accessinggmail/f/Gmail_POP3_Settings.htm
Second: For what you want to achieve (exporting your list of contacts) google takeout seems to be the best fitting solution. More info: https://www.google.com/takeout/
