I agree the Nokia E61 is a great device and sync'ing with Zimbra Mobile "just works". Nokia were correct in calling this phone the "blackberry killer". We bought two test E61's and they worked great for the first 8 hours. And then both just stopped sync'ing, it was totally bizarre and very frustrating.
Looking at our HTTP Apache logs we could see that OWA requests were not even being sent from the phone to Zimbra. If everything is working, you'll see entries like this.
192.168.0.162 - - [24/Oct/2006:14:24:49 +1000] "OPTIONS /Microsoft-Server-ActiveSync?User=zimbra-company\\bill+gates&DeviceId=IMEI356213000206887&D eviceType=NokiaE61 HTTP/1.1" 401 1038 "-" "NokiaE61/1.0"
But when it breaks you'll just receive an error on your Nokia like: "Error communicating with server" Or some other useless message.
So to cut a long story short, I believe (and many others) that there is a bug in "the Nokia software" (not sure if it's Mail For Exchange, the operating system or something else possibly Access Manager). But there are a lot of *very pissed off* Nokia E61 users out there in the World who have this problem. The problem is not Zimbra, it's Nokia.
The Nokia only comes with a very limited set of SSL root certificates (an oversight Nokia?) and there are many reports from people who believe this causes Mail for Exchange to corrupt after 20 or so syncs.
Installing the root SSL certificates for the SSL certificate you are using on the Nokia will stop the request to "trust the connection" each time Nokia syncs and will avoid the corruption / does not sync anymore problem. So if you are using either a self-signed or commercial SSL certificate then I highly recommend you do this - save your sanity!
After many hours of trouble-shooting, I was able to finally get a non-syncing Nokia E61, syncing again with Zimbra. Here are the steps:
1. Turn phone off/on.
2. Install the root SSL certificates for the SSL certificate you are using on the Nokia.
3. Delete and re-create the Access Points.
4. Remove Mail for Exchange (M4E).
5. Turn phone off/on. (You need to do this to clear any residual M4E settings)
6. Download and re-install M4E.
7. Setup M4E Profile to connect to Zimbra.
8. Force a manual synchronisation with Zimbra.
9. M4E should now be working flawlessly again.
10. Now you can get back to your real work (ie. not trouble-shooting phones).
We've not had a problem with the phones since *touch wood*. And I hope this helps others out there who experience similiar problems.
Cheers!
