    The events originally synched, or created in Outlook can not be edited on the iPhone. Can't edit, delete, change time, etc. All you can do is change reminder time.

    If you create an event on the iPhone it behaves normally (edit, delete, change time, etc.) until it is synched and you edit it in Outlook. Then once it synchs, it is locked on the iPhone.

    Also, events from Outlook all generate invitations on the iPhone. As if calendar appointments are being treated as meeting requests once they get to the iPhone. I need to delete hundreds of invitations.

    Anyone else experience this? Am I missing a setting or permission somewhere?

    I'm experiencing the same behavior. I'm syncing everything over the air with Exchange ActiveSync to Exchange 2003 SP2. It appears email and contacts are fine, but calendar entries all appear on iPhone as invitations and are not editable on the iPhone.

    Can anyone confirm that they are syncing with Exchange over the air and calendar items show up OK and are editable?

    Appointments you create with Exchange show as Invitations on iPhone or iPod touch

    The issue has been fixed for me; this apple article describes the issue:

    For me, the issue was that my username and exchange alias in Active Directory (on the windows/exchange server) included capital letters.
    Note that in active directory your name can be formatted differently depending on how your windows/exchange administrator set up your user account, and each one can be formatted differently (username, exchange alias, smtp email address. To find your correct formatting, open outlook; select Tools, Address Book to view the Global Address List (GAL). You will see "Alias" on the general tab and also a list of smtp email addresses on the email addresses tab. This should lead you to the correct way to setup your email address.

    Once you know your email address formatting enter it in your iPhone:
    Open exchange account settings on iPhone. After changing your username it should do a complete resync of your phone; redownloading all mail, contacts and calendar content.

    ZapMyPRAM: does this fix your problem?

    Thank you so much for the information. The difference in capitalization in the email address/account name was the issue. Once the iPhone config matched what was in the Global Address Book, all was well.
    I had about 20 old recurring events created on another exchange server with different domain, account and email info.
    To prove the solution, these still come over as a mismatch for obvious reasons. Once I deleted them and recreated, everything was perfect.
    Thanks for taking the time to reply and provide this solution.

    Didn't Work for me

    I have the same problem, but your solution didn't work for me. Please note that the Global Address Book shows an odd string in place of my email address: "/o=First Administrative ...".

    Still, I tried all combinations of capitals for both the userID (Alias) and email address with no luck. Could it be becasue I'm using Exchange 2003 (service pack 2)?

    Many thanks

    Do Outlook categories and category colors sync across activesyc?
  8. noer macrumors newbie

    I have the same problems, and different capitalization. So should I correct it and turn the on/off slider off and the on, or should I completely delete the account, or what is the best way to do a complete re-sync?

    Thanks from a iPhone newbie!

    I would use the slider to turn it off, exit settings, go back in and then turn it back on again.

    My issue is:

    I'm using QSynchronization to enable me to see the work/shared calendar (by copying the shared/public calendar to my personal calendar) - as activesync doesn't work with public folder calendars.

    However, I have appointments in my calendar created by people other than me - as it is a work/shared calendar(different email addresses) - and the iphone thinks these are meeting invitations when they are not :(

    Wish you could choose to tell the iphone that a specific "invite" is not an invite.

    Even better, the iPhone should look at the appointment/meeting detail and only send me an invite if I am an attendee.

    Hi all,

    I had the originally problem discussed, and found that the capitalization of my alias was indeed the problem.

    Now, I notice though that if someone else puts an event on my calendar I can't edit it. Is there a fix for this?

  12. noer macrumors newbie

    Jul 14, 2008
    I ended up deleting the account from my iPhone and re-creating it. It did the trick. Although, I didn't try turning of the sliders, so I guess that would have been enough, too.

    Thanks again!

    2 email addresses in the GAL???

    Thanks for this help. I looked up my GAL and found that there are 2 SMTP addresses listed for my entry. I must explain that my email address is as This is then forwarded to My email alias on the exchange server is, so that email sent from the exchange server has my correct email address. The 2 email addresses in the GAL are and

    I have tried both email addresses (with correct capitalization) in the iphone setup, deleting the accounts and rebooting the iPhone between attempts, but neither works.

    Could this be causing a conflict?

    help finding Exchange account info


    Thanks for posting the most detailed and helpful description on the web for solving the Exchange calendar event-editing iPhone problem. But in my ignorance of things Window/Exchange would you please provide a little clarification?

    When I go to my GAL info, I do see an item by "Alias" on the General tab with format PartlastnameF. On the E-mail Addresses tab, however, there are four different addresses:,,, and

    Would I assume that my Exchange account name is PartlastF (or perhaps Domainxxx\PartlastF) and the email address

    Last question: does upper/lower case also matter in the name of the Exchange server itself? If I look in Outlook Tools/Options/Mail Setup/E-mail accounts.../view or change existing/ my Exchange server name is given as: domainmbx6.DOMAIN.YYYYHEALTH.PRV. So do I have to match that case format on the iPhone settings?

    OK this is really the last question: should it matter that my email address and the server are so different (i.e., my mail has and the server is yyy.prv?) FYI that has not been an issue getting email either on the iPhone or using Apple as an IMAP client, but just wondering...

    Thanks again.

    I have an original iphone that I upgraded to 2.0 on 7/11.

    I have recently noticed that when I have my Calendar set to show me the month (my preferred view) it lists the days as:

    M T W Th F S S

    where as before the 2.0 upgrade it showed the days as:

    S M T W Th F S

    I want to see it like it was before.

    How do I do that? I've looked in Settings, Calendar but there was nothing there.

    I'm stumped.

    ro-76: I think the address you need to use is the primary SMTP address. In your GAL contact you'll see multiple smtp addresses (username@domain.local, username@domain.tld, emailalias@domain.tld) but only one SMTP (all caps) address, this is the primary address. Note that the capitalization of the username and domain are important. It's also possible that your exchange service provider has created a different "Alias" and that the iPhone might reference this field. The alias is a different active directory property from e-mail address that's used for internal messaging only; you can find your alias on the General tab of your GAL contact. If there's different capitalization in the Alias field, you might try that or You can also try looking at what your e-mail address shows up as including capitalization when sending to an external smtp recepient. The from field should match your primary SMTP address but if it doesn't then there's a problem.

    Unfortunately problems like this do occur with exchange activesync (windows mobile, not just the iPhone) that sometimes can only be remedied by creating a new user account in active directory and migrating all data from one mailbox to the other using a tool like ExMerge to remove mailbox corruption. Hopefully it won't come to this.

    With Exchange your user account is stored in Microsoft Active Directory. When an administrator creates a user account in AD it is best practice to keep things straightforward with respect to account names, otherwise it can get confusing for users. This is only best practice though, and certainly not required. In AD you can modify a user account to have a different account name (windows 2000+), pre-win2000 account name, exchange alias, smtp addresses, X400 addresses, etc.

    Different applications (iPhone via Exchange ActiveSync, Apple via IMAP or WebDAV, Outlook 2007, Outlook Web Access) may interact with Exchange through different protocols, the important thing is to know which account name or email address or server name to use for each application.

    For iPhone Exchange ActiveSync:
    Email = primary SMTP address as referenced in GAL.
    Server = exchange activesync server (usually your OWA server, not case sensitive because DNS is not case sensitive).
    Username = domain\username (not case sensitive, domain usually entered as netbios domain name, not full dns domain name)

    That said, usually trial and error is the easiest way to figure out the settings if not given specific instructions by your exchange administrator.

    It doesn't work for me at all - I tried all combination

    My SMTP in GAL is
    Alias is firstname.lastname

    When I type in, it automatically changes it to lowercase.

    I still can't edit the calendar items after sync

    What can I do? It's killing me
