Exchange Active Sync is not working

I have been reading a few dozen of these post that people are having issues with there iphone sync with exchange. I am TOO!.
For some i can get into owa and from the iphone safaria.
The iphone was able verfy the ssl certificate, but nothing is syncing with mail server
My network infrastructure.
1. Clustered mail server . Running exchange server 2003.
2. firewall- port 443 has been verified to be open and able to acces owa from iphone safari
3. I have NO isa setup in my network.
4. Called SSL verisign company and everything checked out to be fine.
5. virtual folders have been verified to be correct.
6. checked dns report no errors.
7. AD exchange feature mobile services and protcols was verfied to all on.
8. turned off wifi
9. checked all creditals.
And it just won't push anything. I have come to the conclusion that is either IIS or Iphone is using a multiply protocol ports to access the exchange. But i don't know i need HELP
Simple troubleshooting steps to start with:
1. Check your version of Exchange. Must be at least 2003 w/SP2.
2. Check your security certificate. If you go to your "https://webmail.yourdomain.com/owa" or "https://webmail.yourdomain.com/exchange" and receive a certificate error, you may want to look into an external certificate from a recognized CA. I used SBS through my registrar.
3. Check to ensure your "Front-End" and "Back-End" server are not both requiring SSL. That will cause issues with OMA.

Exchange active sync is not syncing calendar from my job's outlook

I have an iphone 4s and configured exchange active sync to have emails and calendar from my job's outlook.
I am receiving all emails from outlook server but no meetings accepted on outlook calendar are coming to my iphone.
What have i did wrong?
I tried unselect others calendars on iphone and keeping active only calendar from exchange, but it did not synced.
I tried changing from push to manual, but calendar meetings still does not come.
I tried to turn all off and on again, but it did not solved the issue.
What puzzles me is that emails from outlook server are syncing perfectly...
Please does anyone knows what is the problem here?
Thank you.

Assuming it's turned on in the settings for the account, ask your IT department.

You don't want to check OWA (Outlook Web Access) as it is a full mail client for a notebook or desktop.
The iPhone uses ActiveSync OMA for syncing. Thus, you want to check https://www.domain.com/OMA (where www.domain.com is the URL to the Exchange server - same URL as the OWA url) with a notebook or desktop. The "s" in https is needed at OMA requires SSL.
You should see a login prompt for username and password followed by a list of Inbox messages. If you don't, the server is not correctly configured for OMA.
Once OMA works from a desktop or notebook, it is an easy procedure to add an Exchange account to a phone. Just follow the iPhone on screen examples and provide only the path to the Exchange server and not the "/Exchange" following.

Exchange calendar syncing suddenly not working on 2nd gen IPOD touch

Calendar syncing on IPOD touch 2nd generation no longer works with Microsoft Exchange server. Mail syncing works fine.

A full restore is probably not going to solve your ongoing WiFi issues - which are causing your YouTube problems. Best bet is to do two things with your router:
1. Pull the plug, wait a minute or two, plug it back in. (power cycling)
2. If that works, you are done. If not, go to the router manufacturer's website and download and install the latest firmware for your router.
If you are still having problems, reset your iPod network settings - tap Settings > General > Reset > Reset Network Settings. When your iPod restarts, log back into your network by this route:
1. Tap Settings > WiFi > Other
2. Enter your network name
3. Enter your security mode
4. Enter your password
You should be all set. However, if you continue to have WiFi problems, please post a new question, with details about your network setup and router, to one of the other touch discussion groups.

Exchange Active Sync wirh Google Mail: outgoing em...

Dear Support,When I compose a mail in Exchange Active Sync, while not being connected to the internet by any means, the mail is saved to the outgoing folder. However when reconnection to the internet by any means, the email is never being sent. Problem is on N8-00 with current Belle firmware and latest Exchange active sync. Error is reproduceable, and only persists in Exchange active sync, not in "normal" mail accounts (such as GMX)

echozulu25,
Luckily I have only spent 2 hours on this same problem. On my old WinMobile phone I was able to create or bypass the security certificate manually. I read on a recent OS update that they resolved this issue, but after downloading the latest OS version I do not see where I can maniuplate or bypass the security certificate error. Did you ever resolve this? Are you aware of the OS update that supposedly resolves this problem? Please advise.

Exchange active sync not requesting advanced setup details

hi - we have exchange 2010 with active sync 14.1 we have many types mobile devices connected using active sync including iphone and android. when we previously added any account onto a phone we always had to add the advanced setup manually during
the setup i.e. mail server and domain. now these details are added automatically after adding email and password. This seems less secure and i need to find how to stop this.
Thanks

Hi ,
This is normal behavior in exchange because of autodiscover feature and it is making up the things easier during new account configuration on mobile devices.
After giving up the user name and password ,autodiscover is the feature which will bring up the remaining settings that you mentioned .
We will discuss in terms of security view .
1.User's password would be confidential .
However in worst cases someone might know about anyone's password and email address then on such case there would be chance to configure that particular account in any of the mobile devices.
We can control the above scenario too.
In exchange Active sync organisation settings we have an option to set the DefaultAccessLevel to quarantine for the devices.So that administrator can decide to allow or block the active sync device which is trying to connect to exchange.
Reference Link : http://exchangeserverpro.com/preventing-new-activesync-device-types-from-connecting-to-exchange-server-2010/
Note : If your existing exchange organisation is having active sync devices configured in use then before changing the "Defaultaccesslevel" to quarantine we need to make sure existing active sync device ID'S are added to the corresponding mailboxes

Exchange active sync not loading emails?

Hi I am currently using a Samsung Note 2 and i've added my Company email account successfully using Microsoft Active Sync options in Email settings.

E-mail and Exchange Active Sync

Planning on configuring E-mail in your Xperia phone? Or do you experiencing problems syncing your E-mails? If yes this might be the topic for you.
Below you’ll find some guides on how to setup E-mail sync and troubleshoot any problems.
POP3/IMAP
POP4/IMAP E-mail accounts are the most commonly used. This guide will show you the steps of configuring your E-mail manually if your E-mail server doesn’t support auto setup. Please note that the Next button won’t be lit if you have typed an incorrect E-mail address containing characters or symbols that are not supported.
Configuring POP3 or IMAP E-mail
Go to the E-mail application and enter your E-mail address and password. Now press Manual setup.
Chose the kind of E-mail server your provider is using. If uncertain check this with your E-mail provider.
Under Incoming settings enter your username, password and server details. If you’re uncertain about these details contact your E-mail provider. But in general your username is the same as your E-mail address but some providers may use a specific user name for your account.
Here you can also set if the server should delete the E-mails if you delete them in your phone. This setting is by default always set to Never.
Next step is Outgoing settings. If your E-mail provider also has an SMTP server you can enter the details for sending E-mails here. This normally requires a sign-in on the SMTP server. If yes, check the Require sign-in box and enter your E-mail address and password. As above if you’re uncertain about any of these details contact your E-mail provider.
If your E-mails provider lacks an SMTP server you can check if your network operator provides an SMTP server and use their details. Using your network operators SMTP generally doesn’t require sign-in.
Now it’s time to set how and when to check for new E-mails. Set and check the options you desire.
The last step of the setup is to enter an account name and your name (signature).
Troubleshooting POP3/IMAP E-mail
First make sure that you have a working Internet connection in the phone.
You can download Internet and MMS settings for your phone by going to Setting > Xperia > Internet settings.
If you have a working Internet connection but still not able to connect to your E-mail server or sync your E-mails check that no Proxy server within your APN settings may be blocking this. You can check this by going to Settings > More (Wireless & networks) > Mobile networks > APN or Access Point Names > Your Internet APN. Check if any details are set for Proxy and Proxy port. If yes you can try to delete them (temporarily) and save the APN. Now check if you’re able to connect or sync with your E-mail server.
You can also verify suspected Internet connection issues by trying via a Wi-Fi network instead.
E-mail disappearing?
By default our E-mail application is set to only mirror the server. So if an E-mail on the server is deleted it will also be removed from the phone at the next sync.
Syncing sent E-mail?
This is not possible on POP3 configurations. To be able to sync sent E-mails in the phone you must have configured an IMAP or Exchange Active Sync account.
Problem sending E-mail?
If you’re not using the same SMTP server as network operator in your phone you might experiencing problems sending E-mail via mobile networks. If this is the case you can connect to a Wi-Fi network to send E-mail or check with your SMTP provider if the outgoing port can be encrypted.
If none of the tips above helps you, you can try to download a third party E-mail application from Google Play store. This can be easy way to rule out where a specific problem may be located.
Exchange ActiveSync
Our Xperia phones come with the built-in Android native client for synchronizing your corporate E-mails, calendar and contacts. Here are some things worth double checking if you would experience any problems with Exchange sync.
Begin with checking your sync account details and if you haven’t configured the Exchange ActiveSync account yet see the instructions bellow.
Configuring a Exchange ActiveSync account
Go to the E-mail application and enter your corporate address and password. Then press next.
Don’t worry if the setup might fail at this point because most Exchange servers don’t have auto setup enabled. In this case just press Manual setup. Please note that the Next button won’t be lit if you have typed an incorrect E-mail address containing characters or symbols that are not supported.
Now our E-mail application needs to know what kind of account you want to configure. Press Exchange ActiveSync.
This will bring you to the incoming settings screen. Enter domain\user name, password and server address. If you’re uncertain about your details contact your IT department to check which credentials to use. You will also need to know if you should accept all SSL certificated or use a client certificate.
When all details are correct you will have to setup how and when to sync. So enter and check the options you desire.
When you see this screen the setup is complete.
If your Exchange server requires certain security settings you might see the following pop-up after finishing the setup. If this is the case you must approve the security update in order to sync E-mail, calendar and contacts.
Pressing OK will give you a screen showing you what permissions you need to give the E-mail application. These permissions/ security settings are set from the Exchange server and depend on your corporate IT policy.
Troubleshooting Exchange Active Sync
First make sure that you have a working Internet connection in the phone.
You can download Internet and MMS settings for your phone by going to Setting > Xperia > Internet settings.
If you have a working Internet connection but still not able to connect to your E-mail server or sync your E-mails check that no Proxy server within your APN settings may be blocking this. You can check this by going to Settings > More (Wireless & networks) > Mobile networks > APN or Access Point Names > Your Internet APN. Check if any details are set for Proxy and Proxy port. If yes you can try to delete them (temporarily) and save the APN. Now check if you’re able to connect or sync with your E-mail server.
You can also verify suspected Internet connection issues by trying via a Wi-Fi network instead.
ActiveSync protocol version
You can check which Exchange ActiveSync protocols that are supported by your phone model in its white paper. http://developer.sonymobile.com/downloads/whitepapers/
Compare this with your server to make sure they’re compatible.
“SERVER REQUIRES UNSUPPORTED SECURITY FEATURES”
If you get the error message above your Exchange server is using security settings which are not supported by the Android native Exchange ActiveSync application. Which security settings that your phone model supports depend on firmware version and phone model. If your company runs on security settings that the Android native mail application doesn’t support and you don’t plan to alter the security settings, an alternative is to download any of the dedicated Exchange ActiveSync applications from Google Play store.
New meetings don’t sync?
If you have entered a new meeting in the phone and it doesn’t sync make sure that the meeting has been put into the correct account. When creating a new meeting in the calendar application make sure that you’ve chosen your ActiveSync account as calendar when creating the meeting.
How to use GAL (Global Address List)?
In most of our models you can access the GAL by opening the contacts application and tap the search icon. This will search the Global Address List on your exchange server. Our mail application also searches GAL when typing something in the To: field. Unfortunately we don’t have any default support at the moment for browsing the complete Global Address List.
For more information about what is supported by our Contacts, Calendar and E-mail applications please see this link (Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z). Or this link (Xperia Z1, Xperia Z ultra and Xperia Z1 Compact).

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
Are you sure that your account is really configured for the ActiveSync protocol? Because we've seen this occur only when using IMAP with Hotmail/Outlook.com.
I suggest that you make sure that the account is configured as POP3 or EAS. Or use their own dedicated app.

Battery drain after 2.2 update (Exchange Active Sync users or those who use a calendar on the phone)

A lot of folks are having "issues" with battery life after the over the air (OTA) update and there has been much speculation as to the cause. My frustrattion level increased with each new post I read that did not reveal a resolution. The back and forth banter about FTC complaints (that was an interesting escape from the battery problem but not very helpful), new apps running from startup (I don't like 'em either), Linux really working better with all these programs running (don't really care as long as the battery level isn't drained after an hour of just sitting on the counter) just made matters worse.
I would like to share with you my experience and hope that it helps some of you who have taken the time to read my post. First, let me say that the cause is not due the the "bloatware" applications that were installed during the OTA update.
Secondly, the primary purpose of my handheld is for voice calls but running close behind is my need for immediate email, contacts and calendar information (which is configured through Exchange Active Sync). If you are not using your phone with Active Sync or updating a remote calendar like Google), you can stop reading this post.
I noticed that the yin/yang (sync) icon at the top of my screen kept popping up more than usual after the update. Looking through the items I have set to sync (Menu -> Settings -> Accounts & Sync), I reviewed all the things I have set and disabled the sync settings for the things I did not want. After disabling the "Backup Assistant", "Google", "News", "Stocks" and "Weather", I thought for sure the issue would be resolved. Not yet. When those adjustments didn't change the frequency of the sync, I decided to look at the Exchange Active Sync and to my surprise, the culprit was revealed - the calendar was stuck in a sync loop (syncing over and over). I disabled the "Sync Calendar" feature and the phone stopped it's maddening attempt to refresh the calendar.
I let the phone cool off and thought that I could get by with manually toggling the option to sync the calendar but I couldn't accept that was the only way this thing would work. I removed the Exchange Active Sync account and created a new one. After the new account was verified, it attempted to sync mail, contacts and calendar but this time, there was a error that occured during the calendar sync. Instead of repeatedly attempting to re-sync, an error message that stated "Client/Server conversion error". At this point, the calendar sync loop was no longer a problem (wasnt' draining the battery) but now my calendar wouldn't sync at all.
To fix it, I cleared the data in the Calendar applications (Menu -> Settings -> Applications -> Manage applications -> All [tab at the top]). Scroll down the list and open each of the Calendar items and click the "Clear Data" button.
(Credit goes to "Brenny" at AndroidForums.com for the post that explains how to clear the Calendar Data)
It seems that adjustments made to events before the update were kept in the phones local storage. After the update, the calendar data in the phone's cache was not matching my remote calendar and appears to have been the cause for my battery drain. After performing these steps, everything is back to normal. Good luck!

Super frustrating, I know. Do you use Exchange Active Sync?
If so, you might be having the same issue that I've explained. Since making the adjustments (clearing the data from the Active Sync components like mail, contacts and calendar), my battery life is back to normal.
Try clearing the data (see first post in this thread) and let me know what happens.

Bug in sample code of Exchange Activ Sync cause birthday shift

Dear Apple Development Team,
Continuing the archived discussion 'Exchange Birthday Shifted by 1 day' I just want to inform you that Microsoft identified the reason for shifted birthdays using Exchange Active Sync. According to Microsoft the mentioned problem is not caused by a server-related problem, but due to an error in a Microsoft sample code which was used in Windows Mobile 6.5, Windows Phone 7, Hotmail Outlook Connector and even in iOS. That means that the client side connection was developed incorrectly. Microsoft and Apple copied the incorrect code from time to time using the mentioned Exchange code in their software (iOS, etc).
However, Microsoft already fixed the birthday bug within the latest update of the Outlook Hotmail Connector (please check changelog) as well as in the current update of Windows Phone 7.5 (Mango). For more information please check the following sites:
German: http://answers.microsoft.com/de-de/winphone/forum/wp7-sync/geburtstags-bug/15075 df5-27f3-4518-8e27-b228d4eaab06?page=1
English: http://answers.microsoft.com/en-us/winphone/forum/wp7-sync/birthdays-are-always- set-one-day-earlier-when/b3d16871-ca24-4a26-a0fc-5b0437904a22
Due to the fact, that the mentioned problem isn't fixed in iOS until now, I would be glad if Apple could fix it as soon as possible, too. This bug is really annoying.
Best regards,
Hannes

Hi,
as far as I know the bug is fixed in Hotmail Outlook Connector now. But in the Windows Phone Mango release the bug is still active in "some" cases (for birthdays in the winter time everything is fine and for birthdays in summer time the bug is still there - or vice versa ).
Does Apple plan to fix that bug somehow? As the bug can be fixed with a new release of Outlook connector and partly fixed in the new Windows Phone release it should be a failure in the code of the mobile devices and not with the Hotmail servers - so Apple developers have to work on that.
Does anybody know when this annoying bug will be fixed?
Cheers,
Marcel

BES or Exchange Active sync?

Hi. (First time poster).
If a company is gonna replace all the old BB's with Z10 (or newer?) do you really need the BES server anymore? The phones are syncing email, contacts and mail. That's it.
Myself, I don't see the use of BES if the Exchange server can do the same.
We started up with a couple of Z10, and still had to use the BES security code to gain access when using Exchange Active sync.
I guess if we remove the server, this wont happend and we just set them up "normally" as an exchange account.
The big issue here is that it might same some money on license(?).
Hope its not to dumb question(s)

Hey HK416,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
There are a few differences between BES and regular activesync:
1. With BlackBerry Enterprise Server 10 you can get the Personal and Work spaces on the BlackBerry 10 smartphone.
2. BlackBerry Enterprise Server 10 also can activate Android and iOS devices and push down policies.
3. The IT admin can push down applications in the work place on a BlackBerry Enterprise Server.
Other than that, BlackBerry 10 supports ActiveSync for enterprise integration with Microsoft Exchange and other enterpris email platforms that use ActiveSync. In fact we already support ActiveSync on the BlackBerry PlayBook tablet today. It will be simple to setup and sync BlackBerry 10 smartphones out of the box with ActiveSync alone, and that’s fine if you don’t need a high level of security and control (ActiveSync supports a small number of policies which are insufficient for most enterprise MDM requirements) so we also give you the ability to add enterprise-level security and management with BlackBerry Enterprise Service 10.
Let me know if you have any more questions.
Cheers.

Cannot Set Exchange Active Sync Email Account ot Default

OK, I am having a problem setting the Default Email Account as Exchange Active Sync. I am seeing this in iPhone and IPad both running 6.1.2. The Active Sync Mail account is installed on both devices and works fine. The problem is I am unable for some reason to change the Default Email Account from iCloud to the Exchange Active Sync Account installed. When I select the option to change Default Email Account, iCloud is there and checked however the Active Sync Account does not even show up as a selectable option here. Please help! Thanks

Hi Flipper507,
Im having the same issue on a couple of devices. I am unable to select my exchange mail on my iphone 5 on ios 6.1.2 but on a colleague of mines iphone 4 we are able to select it. he is also on 6.1.2. on my iphone 5 it also not shows up as an option.
Would like to hear a solution for this.
Kind regards

Treo 755p - Exchange Active Sync

I have been unable to consistently maintain Exchange Active Sync without a "reload or resetting" of the mail, contacts and calendar on my Treo. AirSAMStateMachine.c errors are consistent - for example - 3874 4 Synckey invalid, cmd:4, status 4 is the most recent, but I have had 1913 3, etc.
I've cleared my offline folders, removed the duplicates that this creates at least 4 or 5 times. Reset my devices etc.
Is there any way to fix this? What is causing this? I've checked our Exchange Server and it appears okay - there isn't any errors.
Matt Anderson
Post relates to: Treo 755p (Verizon)

After working for hours on Good Friday, with a Microsoft Exchange technician, we determined that the 755p just does not like a policy being in place on the server,
We even created a new profile after doing the following and the sync stopped until the new policy was removed.
Step 1: Open the Exchange Management Shell
