Iphone Exchange Calendar Synch Issues

Deeply grateful if someone can give me some assistance. We are nearly ready to switch to Blackberry as it seems to synch fine now.

We recently purchased an iphone 3g and want to synch it with our exchange server. We use the Exchange synch utility on the iphone, enter the information, and things seem to synch up...

but...we have missing events, meaning they show up in outlook but they dont show up on the iphone....i would say on any given day, we will be missing at least 1 out of 8.....

an interesting tidbit which must mean something, but what i cant quite figure out is that if i open the outlook client of the user who is missing appointments, click and open the missing appointment, and then just close it out, almost always it will show up on the iphone....

this is bizarre behavior...so, about 90% of the events/appts show up, 10 % dont, but if I open them on the outlook client, almost always the event will show up in a few minutes....any ideas?

Hi Guys,

I'm also having this very problem with my iPhone and one of our sales reps. We've done some troubleshooting and found that appointments which are sent to myself or the sales rep which we DO NOT accept on the iPhone, ie we accept on our workstations, do not appear on the calendar on the iPhone.

Appointments that we create, be on our iPhone or our workstation, and appointments which we accept on our iPhone will always appear in our iPhone calendar.

This seems to have started with the release of the 3.0 firmware, and the 3.0.1 update doesn't seem to have changed anything. I am using a brand new iPhone 3GS, while the sales rep is using his iPhone 3G with 3.0 installed.
We are connecting to a Exchange 2003 server.

Can any of you maybe provide some insite or even solution to the problem.

Thanks
Regards
Dave

We are also having similar problems throughout our entire company.

We are running Exchange Server 2007 with the latest service pack. Our specific issue is that whenever we receive an invite, if we accept it on our iPhone, it does not appear on our Entourage calendar but remains on the iPhone. This problem started to occur when we moved from Exchange 2003 to 2007 and we thought it would be corrected with 3.0.

If anyone has a solution, I would love to find out what it is!

I tried the following, which seemed to work:

When a meeting request is sent, it shows up in Outlook and on the iPhone, before being accepted. After the meeting is accepted in Outlook, it disappears on the iPhone, but stays in the Outlook calendar. This scenario happens when the meeting is accepted without sending a response. The problem is also present when delegates accept a meeting request on your behalf.

If the meeting is accepted using the “Send a response” or “Edit the response” options, the meeting will stay on the iPhone.

At our company we are having this same mystery problem since the 3.0 firmware update. The problem isn’t consistent, about half of the users have the problem and half don’t. We have 3G and 3GS phone all using 3.0 or 3.0.1 firmware with Exchange 2003 SP2 Outlook 2007 SP2. The only thing that appears to work for us right now is when creating an event or appointment is to add yourself as an attendee. When you add yourself as an attendee to your own event or meeting the event will appear on both the outlook calendar and the iphone. I can also confirm that if you accept a meeting request on the phone it does populate both the outlook calendar and the iphone. So the only problem we are left with is when items are created directly into Outlook or meetings are accepted in outlook and not on the iphone the iphone calendar is not populated with the event. This is mostly a problem for users with assistants who add events directly to calendars and who accept meeting request on behalf of others. As with most others the calendar sync has only recently became a problem since 3.0 firmware.

As an update to my earlier post, adding yourself as an attendee to meetings and events does work, but if you delete the meeting response email from your inbox the calendar event disappears from the iphone. Also if you move the meeting response message from the inbox it will disappear, so as a test we moved a meeting response message to a folder and the meeting disappeared from the iphone, then we moved the message back and the meeting reappeared on the iphone. It is almost as though the iphone is looking in the inbox for calendar information and not at the calendar folder in exchange.

Thanks all for your updates. All of these workarounds are pretty worthless though when you have a large user community. There's no way to enforce certain rules for certain appointments. These items either sync or you have to assume that they don't. An earler post asked if Apple had been contacted - I'm fairly new to these discussion groups - how do they get notified - it would surely be good to hear from them that they at least acknowledge that there is an issue and that they are going to address it.

Sorry all my iPhone users are affected with this calendar sync problem. Items that are added directly to the calendar in outlook don’t get synced, but meeting request and accepted meetings (accepted from the iphone) do. In my case I never add items directly to my calendar everything on my calendar are accepted meetings that are synced, but as soon as I add an item directly to my calendar it won’t sync. So in the case of executives that have assistants that populate their calendar for them those items wont sync and that is the killer for our organization.

All of our i-phone and windows mobile users are reporting the same issues to varying degrees. Our heavy calendar users, Sr. Staff, use the i-phone so the issue is reported more by them.

We've noticed that updated meetings are the first to disappear from the mobile device. Sending an update and requesting a response appears to keep the updated appointment on the phone.

We've seen this problem for several months however, and wasnt related to the 3.0, or 3.01 upgrades.

Our IT service provider has noticed several Active Sync errors on our server and another client's with the same issues. Through them we are in contact with Microsoft and seeking a solution.
