Exchange 2003 only allows 2 iphone connections

I have Exchange 2003 - Server 2003 SBS and am able to sync email with 2 iphones however it will not sync additional phones although it does authenticate the accounts. In the event viewer it get the error message: Source: ServerActiveSync Event ID: 3005 Unexpected exchange mailbox server error: Server......HTTP status code: 409. Verify that the exchange mailbox server is working correctly. Is there a setting somewhere where I can let activesync allow more than 2 connections? Like I said I do have 2 customers who can connect and sync without a problem. Thank you

Thanks. We'll let you know when a new response is added.

It seems from your question that you are talking about a separate email account for each iphone. In the users properties in AD are the new users enabled for active sync? You did not say whether you checked that. There is no default limit of two connections in exchange 2003, but you do need to make sure each account is enabled. I believe in Exchange 2003 all users are enabled by default, but that may not be true in your organization. In ours we disabled all users so we could control who connected and to make sure noone was connecting using a personal device. We then enabled those who had company owned devices and when new users are added to exchange they are disabled for active sync by our creation policies. They have to open a request to be enabled.

    I noticed that when using an iphone you don't need to install a certificate on your IPHONE where with a nokia you must. At least noticed this at my office where i connect with a N95 to my office and have to install the cert on that phone, last week i bought een ipod touch, dan this one gets my calendar from exchange without cert. So you might want to check if the other phone dont accidently need a cert. Hope this will help

    Thanks for your reply however we have 4 identical IPHONES (3G) that we purchased on the same day and only 2 of the users can connect so I was wondering if there is an limit to how many can connect?

    I have customers that use many many different devices, with the various versions of Activesync (Nokia, Windows Mobile, Roadsync), and none of them are limited in anyway for the amoutn of devices. Could you possiby have either a problem with IIS, not letting enough sessions work for the devices (as activesync uses iis and the OWA/OMA website to work) Or do you have some sort of session limit on your internet connection? Can you get more than two http sessions from outside the network working?

    Oh and also, while you are looking at OWA from outside the network, check that the users can login to OWA, preferably both at the same time.
