Using an iPhone with SBS 2003

iphone_emailYes, you’re on the right blog. Don’t freak.

Not too long ago, a customer with a shiny new iPhone called and wanted to get it hooked up to their Small Business Server 2003 server.  No biggie, right?  Well, POP3 is one thing, but little did I know then that IMAP on SBS with an iPhone was pretty much uncharted territory. 

It took a fair amount of research, lots of experimentation, plenty of help from
Eriq Neale [SBS-MVP], and an enormous amount of patience since the client with the phone was 500 miles away and we were doing this blind.  (Yikes!)

I’m happy to report that the iPhone does work with SBS using IMAP with SSL.
(Although Windows Mobile 5 or 6 with Small Business Server is still the preferred tool for mobile SBS Warriors).

Want to set this up for yourself?  No problemo – there are two phases:

Phase 1 – Setting up IMAP with SSL on the SBS box
(complete with screen shots).

"Configuring IMAP over SSL with SBS 2003 Standard"

Co-authors: Eriq Neale & Tim Barrett

As a reminder, make sure you open ports 143 (TCP) and 993 (TCP) in your firewall and forward it back to your SBS box.

These instructions are for SBS 2003 Standard.

UPDATE: Eriq has also completed the ISA version of the instructions for SBS 2003 Premium.

Phase 2 – Setting up your iPhone to work with SBS and IMAP
(complete with screen shots stolen from UW and modified).

  4. Fill in your account information as follows:

      Account Information:

    Name: Your Real Name
    Description: SBS Email (Just a suggestion)

      Incoming Mail Server:

    Host Name:
    User Name: username (Not domain\username)
    Password: yourSBSpassword

      Outgoing Mail Server (SMTP):

    Host Name: (:587)
    User Name: username (Not domain\username)
    Password: yourSBSpassword

    This page should now look like this:


  5. Touch Advanced to configure security options.


  6. The following screen will appear.


    I used the following settings for SSL on the iPhone:

    Incoming Uses SSL – On
    Outgoing Uses SSL – On

UPDATE: Props to Levent for reminding me that you need to make sure that both ports 143 and 993 open and forwarded to the SBS box. The instructions are in the whitepaper, but I didn’t have inbound 993 turned open in my initial configuration, which is why I couldn’t get the iPhone to pull down email via IMAP with the ‘Incoming uses SSL’ turned on initially. Thanks for catching that Levent!

So there you have it.  Thanks to Eric Neale for his amazing patience and Mac & SBS know-how!  And thanks to Susan for the link. 🙂
