We are using Exchange 2007 and have recently enabled Pop3 by starting the service on the server. However, when I try to enable Pop3 for specific users using the mailbox features tab of those users, Pop3 does not show up as an option. Is there anything else I should be doing? Brian Gould

Hi Brian, Run Get-CASMailbox cmdlet and see if POPEnabled setting is true or not, if it is false then run this command and enable it. Set-CASMailbox UserName -POPEnabled: $true (remove space after : in-POPEnabled: $true while running command, it doesn't display here properly so I added it) After setting these check in Mailbox Feature and see if you are able to see it or not.

Brian: The only thing I will add to that is you also might check or set the authentication type using get-popsettings and set-popsettings -logintype ? On my test server I have pop (and imap4) enabled and used set-popsettings -logintype 'plaintextlogin'

Hello Amit, By default E2K7 mailbox comes with POP3 feature enabled. And I don't think you need enabled it again by running above cmdlet's given by you. Is there any way todisable POP3 feature while creating a mailbox. It can either Resource or Linked mailboxes also? If yes, please let me know the details regard this issue.

No, you cannot define defaults like that. The second best thing would be to define a group of allowed POP3 users, then run the above cmdlet and disable POP3 for anyone that is NOT in that group. And, of course, schedule that command to run every so often to set new mailboxes.

Many thanks. We have got pop3 enabled using the cmdlet although it is still not showing as a mailbox feature. We dont normally allow our users to use pop but it was required for a problem management solution (TrackIt) which generates work orders from received emails using pop.Brian

Brian, when you say that POP3 is not showing up in the features list, do you mean the Mailbox Features tab of the user's mailbox information in the Exchange Management Console? Do you have the E2K7 SP1 version of the management console installed?

Jim, Thanks. Do you mean POP3 feature doesn't enabled automatically? Do you have proper step by step if this not enabled by default? But I see in my lab machine, whenever you create a new user mailbox (not talking about any room or linked mailboxes), check the mailbox features tab, it shows POP3 feature as Enabled, even if POP3 service is not started or disabled also. I think in E2K7 setup itself is hardcoded not too sure, need to log a call with Microsoft PSS support to find out why exactly POP3 feature enabled by default.

No, I meant that POP3 is enabled by default for new users.

Pop3 is enabled by default for all. We just disabled it for everyone except the few we want to authorise using the cmdlet. We are planning to upgrade to SP1 soon but not running it at present. Brian
