    This is what i figured out so far.. .and it seems (most likely) to be an issue with the 2G/3G provider. But dont know what hte 2G/3G network provider/carrier should change to make it work for my connection. Also not sure if all exchange server users under this network is having issues or if its isolated to only few users


    Don't know if anyone else experiened similar pattern.... and if hte conclusion makes sense? One more observation is that even in iPhone 4 Safari - i'm not able to go to the https://<server name> site which was working before iOS 5.1 upgrade. Same server name i use to setup my exchange server mail box as well


    My iPhone 4 - CarrierA -

    Exchange server works fine in Wifi

    Exchange server doesnt work in 3G/2G for both me and my friend's exchange ID


    Friend's iPhone 4 - CarrierB -

    Exchange server works fine in Wifi

    Exchange server works fine in 3G/2G for both me and my friend's exchange ID


    Swapped the SIM card between the phones and tried

    My iPhone 4 - CarrierB -

    Exchange server works fine in Wifi

    Exchange server works fine in 3G/2G for both me and my friend's exchange ID


    Friend's iPhone 4 - CarrierA -

    Exchange server works fine in Wifi

    Exchange server doesnt work in 3G/2G for both me and my friend's exchange ID

    For us, this turned out to be a corrupt mailbox on the Exchange server.  We moved the mailbox to another store, repaired the mailbox and defragged it.  After that everything is back to normal.


    I doubt this is the same for everyone, but the simptoms are the same.



  • tbasl Level 1 Level 1

    Chronicfathead - This sounds like it could help me because I had some really strange activity yesterday in my mailbox like someone had hacked my account.  How did you go about "moving" and "defragging" the mailbox?


    Thanks for the help!

    Thanks for the reply, however, if you read my post and most of the posts on here the problem is just the opposite.  Exchange works with 4g but not WiFi.  Continues to be an issue...  Arghhhhhh!  That's not directed at you but at the issue.

    Hi Guys

    I faced the same problem when I updated the iOS from 5.0.1 to 5.1 on my iPhone 4s. I spent about 3 hours trying to solve the problem. Finally I was able to work out this tricky issue as following:


    1. Go to settings
    2. General
    3. Reset
    4. Reset Networking Settings
    5. Settings
    6. General
    7. Network
    8. Switch the Wi-Fi On
    9. Enter your Credentials (check you internet connection by accessing any webpage, i.e.
    10. General
    11. Setup your Microsoft Exchange account
    12. Restart your phone
    13. Test sending and receiving


    The above procedure solved the issue and I was able to send and receive messages through the exchange using my iPhone 4s. you may notice that I went through a detailed steps but it will take about 2 min to be done.


    I hope this will work for you too.

    We are having problems with numerous iphones in our office since the 5.1 upgrade - everyone has Exchange.  I have a 4S, and have had no problem, but the 4's and 3's aren't working, even after hard resets, trashing acct and reentering it, wifi and/or 3g/4g.  There was a story in the paper the other day that since 5.1 and the new ipad came out, the 4G networks are overloaded for both ATT and Vz.  More people trying to watch HD on their devices and the downloading of the IOS.  I have a feeling this is a big part of it, but doesn't explain why it won't work over the wifi.

    Ok all I have a solution to my issue!! This may also be the solution to some of your problems as well. I met with our IT department today to find out that our server address has changed due to the upgrade of Enterprise Exchange accounts. I put in the new server address and it started working back with no problems. So you may need to check with your IT department to see if your addresses have changed with the new Microsoft upgrades. Good Luck to All!!!! Thanks for the info it really helped me to figure out my issue

  • TechnoKOZ Level 1 Level 1

    Norskboy, what version of exchange are you using? Is it SBS. 

  • w3nitro Level 1 Level 1

    Im not sure what SBS is. But our network has upgraded to Microsoft Exchange 2007, 2010. When they made this change they also change the address to acces the exchange email.

    I'm having the same problem - my Exchange e-mail on my new iPad randomly stopped working this morning, but my iPhone4 (not a 4S) continues to work fine.  I had moved a sizeable folder out of my Exchange Inbox and onto a personal folder on my computer - maybe this is like chronicfathead's corrupt Inbox solution.


    I tried the 12 step solution from Asiri, but no joy.


    Given that both devices are running iOS5.1, it's weird that there's a difference between the devices.


    Update - now my iPhone isn't working...  must be an Exchange issue.

  • clwill00 Level 1 Level 1

    Yes, I'm having the same issue. iPhone 3GS and new iPad 3 both running 5.1 (the iPhone was upgraded) and connecting to exchange email over wifi is terrible. "Loading..." or "checking for email..." for many minutes at a time  Almost non functional. Of course the iPad is wifi only so there's no choice.


    Apple, are you listening? This is broken!

  • storm_22 Level 1 Level 1

    I am having the same issue that everyone else has talked about but I don't think it has anything to do with the Exchange servers.  I say this because I have a Samsung Galaxy 2 that is also setup (work phone) to receive the emails and the email arrives at the same time as my laptop.  Because I don't want to carry both phones I setup the exchange server on my iPhone 4s and everything was working fine but I noticed yesterday that I missed some emails at lunch.  I have been testing this with all your suggestions this morning and nothing seems to work with the iPhone.  I continue to get the emails very fast on the Galaxy but not the iPhone.  Any other suggestions would be appreciated.

    Hi all, same issues we are facing since we upgraded our iphones and ipads but little differently as, one of our users has approx. 4,000 contact in his address book at his mailbox at Exchange 2007 SP3, after couple of days and some times same day his contacts getting multiplying and ended up on 50,000, 60,000 and sometimes more if his mailbox is out of monitoring, we need to stop synching mailbox with Exchange from iPad so that he can get emails and all on his blackberry and on his Outlook properly, still searching to resolve this issue, everything else i.e., emails and calendars are working fine on wifi as well as with network operator's connectivity, meanwhile after disconnecting iOS devices from Exchange server user is using Samsung Note with Gingerbread 2.3.6 and everything is working fine, so the issue is at iOS end that gives prolems differently to different users, Apple needs to address the issues immediately.

    We have about 1700 student iPads running iOS 4.3.5 on our campus, and reports are starting to trickle in that clients can't receive mail any longer as of this morning. The affected accounts are Google Apps for Education accounts configured as Exchange accounts. I am also not able to get mail on my iPad running the latest 5.1.

    The error I am seeing in the Mail app is "Cannot connect to mail server".


    I'm hoping Apple fixes this ASAP. :/



  • storm_22 Level 1 Level 1

    I fixed my problem by restoring the iPhone and NOT using the backup.  I just reloaded everything I needed and set up the iPhone as new.  No problems now.  Receiving all exchange emails.
