Sorry not sure if this is the best topic to post this in. Just got my new iphone and trying to connect to the exchange server. Get an error:

Unable to verify Certificate
The certificate from mail.*.co.nz for account """" could not be verified.

I click Accept and it says verification failed. Belive the issue is a problem with the security certificate but not sure why it says """". Hoping someone might be able to help

Maybe your SSL certificate for Exchange is self-signed (so it can't be validated), or it may have expired...

Thanks very much for the help. Exchange is not something I have played around with too much especially the certificate side of things; our guy who does this side of things is away on leave for a while. Have checked in IIS under Exchange and the certificate shows it is issued to the mail server and until 2010. It is called an SSL certificate for OWA which I think sounds like what it should be.

I did read the following and wondered if this may be an issue? Not sure what the ActiveSync server name refers to?:

The iPhone might now warn you that it couldn’t validate your account.  This is because it couldn’t correctly pick out your exchange server name.  If this is the case, enter your server name in the window.  Make sure you enter your ActiveSync server name, not the OWA server (as in Entourage) or the real Exchange server (as in Outlook).

**Update**

Have been checking some more and found out the Active-Sync directory did not have ssl authentication turned on. Enabled it and the iphone said the account had been verified in the setup screen. But if I go to my inbox it can't find any messages and am unable to send ' An error occured when delivering this message'. It also occassionally pops up and says it can't verify the certificate

It sounds like your Exchange server has a self-signed certificate. In that case, you might be out of luck. Try Googling for "iphone self-signed certificate exchange".

The other option is going to www.certificatesforexchange.com and just buying one. ;)

Saves a lot of hassle!

Thanks for that. Managed to install the certificate on the iphone and got it working correctly. Only thing left now is to get my calendar to sync. It is syncing my personal calendar which I don't use since we just share a public calendar. Can't seem to find any way to change it. Be good if there was a way in exchange to tell it to use the public folder as default calendar

Exchange ActiveSync syncs only personal folders, not shared folders.

is there a cheap application/plugin that will automatically copy calendar from public folder to a personal pst file?

If you have a self-signe certificate you can just get around the authorization error by saving your settings. Then go back into the configuration and turn off SSL. You should connect with no problem.
But I recommend going with a SSL cert you can a cheap one for around $30.00 USD

Hi ader,
Have you tried just exporting your shared calendar .pst then importing into your personal one?

Also note I just posted in another thread that Apple's implementation won't sync anything but "Inbox" - so if you have server side rules moving incoming e-mail to specific folders, you won't have those on your device.

Also it won't work for meeting requests.

Hi, I couldn't find how to copy manually from the public calendar to the personal one. I did see that you can copy to a personal folder but this creates a new calendar not update the default existing one. It would have meant the two calendars weren't synced. The cheapest option I have found is QSynchronisation a plugin that hopefully do what I require. Am testing it in the trial version. So far so good, it's copied the calendar, my iPhone has downloaded it and I've been able to accept and decline invitations fine... :)

It responds and updates fine.
The issue is that you cant create a meeting and invite people from the iphone.

Im having a couple of issues, one i know what the solution is but the other is a little annoyning.

If you running Exchange 2007 without SP1 attachments dont download. SP1 should fix this.
Second issue is that if im connected to our internal wireless network, push email stops working after a short period of time after a restart on the handset. Soon as i switch to 3G it starts working again.

Edit: Found out whats happening with my wireless issue. http://support.apple.com/kb/TS1868
