Question

How to disable POP mailbox access by default on Exchange 2007?

Asked by: Ozone214

On Exchange Server 2007, how can I have POP disabled by default for any new mailboxes, but still allow it to be explicitly (and manually) enabled for specific mailboxes?

I know that I need to start the POP3 service, and that I can use set-CASMailbox to enable and disable POP for individual mailboxes.  However, every new mailbox I create automatically has POP enabled, and it therefore must be manually disabled.  We have a few legacy applications (like our help desk software) that need access to a POP account, but I would rather enable POP access on a case-by-case basis than have to disable it on newly created mailboxes one at a time.

There is no way that i know of to have it be disabled by deafult on newly created users.

i think this type of thing is where you would need to get creative, and use your knowledge to work around this. scripting is definitely an option here. first off, for all newly created mailboxes, you could disable it all in one fell swoop using powershell after the accts are created. powershell has the ability to do loops and other common scripting functions.

i am an old 'vbscripter', and if i were going to do something like this with vb, i would likely create a list of all accounts that should be pop enabled. then find out what attribute that corresponds to in AD. i would write a script that runs through all accounts in the domain, then if it finds one that is pop enabled, i would have the script run through the 'allowed' accounts file list, and if no match is found, i would have the script turn off pop for that account. i would then schedule this as a scheduled task at whatever interval i deemed necessary.

i'm sure something similar could be done with powershell, but you'd need to experiment and find what works best for you.

Thanks Kris -

Aye, that's the route I'll take as a fallback - I'll have a powershell script that runs daily which first disables POP on all mailboxes (using wildcards, essentially) and then re-enables POP on the specific mailboxes that need it.  The only trouble with this approach is that when I add a mailbox that does need POP enabled, I'll need to subsequently modify the script to add that new mailbox.

Still a decent solution (since it requires less per-instance work than manually disabling POP on each new mailbox), but I'd love it if I could just have them disabled automatically without a regularly scheduled script.

If nobody can tell me how to have it disabled by default, or if the question remains otherwise unanswered (as, for some reason, mine tend to do), I'll accept your answer as the solution (and post a copy of the powershell script I write).

Regards,
Greg

i did some double-checking, and still say there is no way to change the default behavior. here is another workaround i came up with.

i set one of the 'custom attributes', 13 in this case, and gave it a value of "POP". This denotes users that are authorized for pop access.

now we know that
get-casmailbox | where {$_.popEnabled -eq "True"} will give us all users enabled for POP

get-mailbox | where {$_.customAttribute13 -eq "POP"} gives us all maiilboxes where this custom attribute has been set, effectively, all users who are 'authorized' for pop

so,
get-casmailbox | where{$_.popEnabled -eq "True"} | get-Mailbox | where{$_.customAttribute13 -ne
"POP"} | set-casmailbox -popEnabled:$false

will find any users that are enabled for pop, but who do not have custom attribute 13 set to "POP", and will disable pop for those users en masse

i don't see why this couldn't be saved as a .ps1 file and then set on a regular schedule. all you'd need to do at that point would be to make sure attribute13 is set to whatever you want it to be when pop authorized accounts are created.

Brilliant!  Thank you very much - I have just finished implementing this, and it works perfectly.

 

by: Ozone214Posted on 2007-07-12 at 13:07:24ID: 19475676

Just so it's visible in the thread if somebody else is looking in the future, I've added one other line to my script:

Get-CASMailbox | where {$_.popEnabled -eq 0} | Get-Mailbox | where {$_.customAttribute13 -eq "POP"} | Set-CASMailbox -PopEnabled:$true

This is basically the reverse of your command.  With this line, I can retroactively enable POP on a mailbox just by modifying the Custom Attribute - so my administrators need only change the Custom Attribute in the GUI, and all accounts will be enabled/disabled as appropriate the next time the script runs.

Thanks again, Kris.

i gotcha. so you have one script with both lines.

one other thing, the case insensitive comparison operator (-eq, i think, might be case sensistive), is -ine, or ieq. might want to change those so you don't have to worry about whether they put in POP or Pop.

Kris.
