Exchange ActiveSync Issues with Android 2.3.3
Situation: After upgrading your Android phone to 2.3.3, you may receive an error message "your client doesn't support the necessary feature" when sync email and Calendar with Exchange server.
Case 1:We experienced the same problem (Android 2.3.3 & Exchange 2010 SP1) with ActiveSync but found a solution that worked for us. In our case we had to check the "allow non-provisional devices"-checkbox in the ActiveSync-Policy-Properties in order to use ActiveSync with our Samsung Galaxy S II. After deploying the policy, the connection could be established and everything worked fine - the necessary changes like defining a password according to the policy etc. could be applied to the mobile phone.
Case 2:If you are using E2K7/E2K10 some phones don't like the PIN code security feature like the dam HTC Hero so you have to turn it off and set the policy to default to allow normal authentication.
Case 3: it could be the inheritable permissions. You have to set an option on a AD server in your account. On the security tab click on advanced then set the option "Include inheritable permissions from this object's parent".
Case 4: Found the problem. Password had special characters... As soon as we rid the password of any "&", or "@", it seemed to work. Thought I would share in case anyone else is having that issue.
Case 5; I spoke to one of my IT guys. We took a closer look at the Exchange server. First our SSL certificate was not issued to the protocol of a mail server (support.****.com) instead of (mail.****.com) and it was not properly installed. He deleted that certificate and I was able to connect right away, with the SSL box UNCHECKED.
Since we didn't want to leave the server without a SSL, we then purchased a new certificate with the proper name (mail.****.com) and installed that. Again, I connected right away, this time with the SSL box CHECKED. To verify, I tried to connect with the SSL box unchecked, I was not able to. This is the first time we ever tried to connect a phone to this Exchange box using ActiveSync. After this we were able to connect another Droid phone to it without any issue.
I tried two Honeycomb tablets, both having the same issue, they cannot connect to Exchange mail, throwing error messages talking about sign in errors. See here http://code.google.com/p/android/issues/detail?id=16992#makechanges
Case 6: It seems that individual phones ask for the setup differently. I was having an issue using my DRIOD X ver2.3.3 but finally got it to work.
Case 7: Have a Samsung Galaxy SII, with Exchange mail problems.
This solution worked for me
1) Erase my phone, back to factory settings
2) When starting the clean phone, i signed in to my google account
3) Setup the exchange account
4) It worked
Case 8: I am not sure why. But it seems like after doing this I was receiving a security settings feedback/message from the exchange server. Earlier I was prompted with question about whether to accept the exchange server change my security settings, but nothing happened after I accepted. Know I got this status message with a list of all security settings the exchange server may modify. I then accepted this, and finally I could synch my mail and contacts.
Case 9: if you change your Exchange password, you need to change it on your phone as well. My calendar had been syncing beautifully until about a week ago, when it suddenly stopped. It finally occurred to me that I hadn't changed the password in my settings on the actual phone as well.
Case 10:Change the screen lock to PIN.
Case 10: Had the same problems in the Samsung
Galaxy S II but that was apparently because I did not accept to be part
of the "Samsung Social Hub".
Case 11: If you have the problem that you cannot configure at all and you get a security error (With a reference to APN), then the solution is simple:
Go to security settings of your phone en create a PIN lock with at least 4 digits. Try it again and it works. Tested on 2 phones.
Case 12: Solution that did it for me: Logged on to the webmail exchange client, clicked options, then to the left there is an option for managing mobile units. There i found my phone in two versions, IMEI same but different user agent codes (thus the error?). I deleted all of the mobile units, then without warning, the phone rebooted, deleted everything in the phone, resetting it to factory standard. I then added my exchange account again, and voila, it work...
Case 13: I found a solution.. I think calendar sync
won't work if ur employer company policy forces to use device PIN lock
functionality. Here is solution:
1. Just activate password/PIN protection for your phone Lock screen by setting a PIN lock for device screen
2. set Auto-sync ON in account settings
3. then reconfigure ur exchange a/c once.
After sync .. u will be able to see ur exchange calendar name in device's "Calendars" list.
Case 14:1. Make sure the user you plan to sync with your server is member of the mobile users
2. Create an exchange account on your android phone. >> Check "accept all SSL certificates" option <<
3. It will pop you a security warning that you will accept.
4. Go in your notifications. There will be a security warning from Active Sync that ask you to set up a security code for your phone. (It wont accept a pattern security access) This is part of the security policy embedded in Exchange. You can tweak it in order to remove this feature, but NOT recommended in a corporate env.
5. As a verification point only : Login to OWA. GO in settings, show all settings and in the left pane, select "phones" to make sure your phone is there. You may see it twice but do NOT delete any of them.
At this point, synchro should be done and you should see stuff traveling back and forth.
case 15:First of all i backed up all my video's, pictures and music on my pc.
then i did a factory reset on the phone which asked me if i would also like to delete data on memory card as well, so i selected that as well.
then when it restarted, i activated the phone again on the carrier,
signed up with my google account on the phone,
then i tried setting up my corporate account and i was able to set it up, then it asked to reboot and it did,
