Almost everyone who updated to i OS7 today can't connect to our Exchance 2010 server for email. Has anyone else had this issue or know of a way to fix it?

iOS 7

    Talk to your IT people.  I've updated to iOS 7 and have no problems connecting to my corporate Exchange account.

    Same issue here. Must be a bug in iOS 7.  After the upgrade, both iPhone and iPad failed to connect to the exchange 2010 server.  Tried deleting and setting up account again to no avail.  Surprised it's not discovered during the beta testing.

    There's no bug.  Again, talk to your IT people.

    Did some troubleshooting, no solution yet, but below is a portion of the Exchange 2010's Activesync log. The 110 status code at the end indicates "Unknown Server Error" during the initial Provisioning phase, thus all the subsequent AirSync requests are denied.

    @lanfromusa: What SP is your Exchange 2010 on?

    Now again same issue with the iOS 7 release - we use Rackspace hosted Exchange 2007 on a single domain (closed network). The issue seems to be with with authenticating the password and other user specific account information. There are a handful of threads for this issue - no solution yet. Most iOS support threads are discussing issues with activation post iOS 7 update due to suspected Apple activation server issues.  (Thank you for referring end users to their "IT People" however this does not work in my case as I am one of two IT professionals for a small company. Any ideas for temp workaround?


  • KEBW Level 1 Level 1 (0 points)

    Update: Apple support confirmed that there are still issues with iTunes and Activation servers that has caused issues with many users attempting to install iOS 7 and has effected many users ability to log in to their iOS accounts - universally for all devices and OS's. They are still working to correct the issue. In the meantime I suspect that it is possible Exchange acct.users attempting to log in and authenticate using SSL/advanced security settings may be unable to because they must be a valid (authenticated) user with appropriate log in credentials in order to recieve a securirty certificate.


    Does anyone else have any ideas for a viable solution or any additional info?

    I can receive, but not send.  Brutal.  Rebooted multiple times, deleted and re-added an account, no love.  Multiple Office 365 accounts.

    Oh...and initially they at least showed up stuck in the outbox.  Now they're just gone.

    I am having the same issue. Exchange server 2010 stopped working after updating to iOS 7 on both iPad 2 and iPhone 5. Deleted account on the phone and tried to set it up again to no avail.


    I'm furious Apple!!!! Grrrrrrr

  • UsaskMobileAdmin Level 1 Level 1 (0 points)

    We are running Exchange 2010 SP2. Many iOS7 devices stopped syncing to the Exchange server when they upgraded to iOS7.


    We restarted the Exchange servers last night, and that fixed sync for some users (not all).  However, if those users remove and re-add their Exchange account in iOS7 again, then they can no longer connect.  Any accounts added to brand new devices cannot sync at all.


    There is still a huge problem between Exchange and iOS7.
