I wonder if anyone else is experiencing the same problem.

My company offers Outlook Web Access to enable users to access their mail via the Internet. Some users use only the web mail, while others use Office Outlook at work... When I came upon this fix, I wasn't even at work anymore, so I couldn't double-check the Exchange settings in Outlook; I was at home. After reading some discussions about how to integrate OWA to the iPhone mail settings, I decided on a whim to set up my Exchange account using the address of the company's webmail server instead of the internal mail server address. In my case, it's webmail.(companyname).com. I made sure SSL was on. To my complete surprise, everything began to sync! This had never happened before; even when Exchange worked, I could only sync while connected to the company's wireless network. It took several minutes, but I eventually had all my mail, contacts and calendar events back, and I weas able to send and receive company mail as if I were there.

The above fix might be worth a try. I'll be interested in seeing the results if anyone does try this.

iOS 4: Exchange Mail, Contacts, or Calendars may not sync after update

Activesync is the mobile sync protocol for Exchange. You cannot use activesync with Outlook, it is only for mobile devices. Google sync is just Google's name for its implementation of the activesync protocol.

This surprises me as it is possible to chose which account to send mail from, or to which calender I add a calendar event.

Hope they address this one in ios4.01

To the poster about his IT dept shutting off his access... Unfortunately, ActiveSync permission is managed on the Exchange server. No work arounds yet...

The only complaint is the fat that Auto-Lock is forced to 1 minute and cannot be changed. I use a GPS app on the golf course and I have to remove my account to set Auto-Lock to "Never" when playing, then add the account back after. I understand the security needs of companies, but this should be optional (especially since it does not force a required pass-code to unlock.)

The new automatic imap configuration is sweet though!

There is an Exchange security policy that controls this, and the glitch apparently happens when there is >no< policy setting. I ran into the same thing with my iPhone and a Hosted Exchange service, however, I was able to change the setting myself in the admin control panel; GoogleSync allows minimal user settings for this, and AutoLock isn't one of them unless you want to require a user password to turn on the device, then you can set it to a max of 30 minutes to autolock, but you can't shut it off (or change it from 30 minutes to something else).

It's a pain, but but for now I use the standard Gmail sync for mail, calendar, & notes (a recent addition) and iTunes has an option to sync with Google Contacts (but not mail or calendar).

This is the 2nd time Google Exchange ActiveSync has broken this same way, something they already fixed once about August 2009; it's back for iOS users.

A friend has a Hosted Exchange service, which works fine with her iPhone4.

I wish the maintenance will fix this.

http://www.google.com/appsstatus "This is a notification of upcoming scheduled hardware/software maintenance. During this maintenance event, Google Sync will be down from 6/26/2010 at 10PM PDT for approximately 4 hours until 6/27/2010 at 2AM PDT. For more information please refer here."

there were some major hiccups on the day that i upgraded my 3G to iOS4, but those smoothed out later in the day and everything worked fine after that.

then i got an iphone 4, and contacts worked but only one of my calendars would sync. i remembered that all the calendars [up to 25] have to be enabled on a device by device basis on the google sync management webpage.

so i enabled the calendars on the new iphone and everything is fine now, no problems.

Seems like the google exchange servers were overloaded so exchange, mail, contacts, and calendars were all screwed up. I was getting mail out of order, my contacts weren't populating, and I was not able to send emails.

Also my battery was draining at an incredibly fast pace. My phone was hot and my battery was draining at about of 1% every 1 or 2 minutes with the phone on standby. Seems like exchange got "stuck" in the background and was constanting establishing a connection.

Since then I switched over to imap with 15 min fetch and it worked fine and battery was back to the pre 4.0 days draining at a normal rate. I will attempt to go back to google sync today and see how it goes.

I don't use two Exchange accounts, though.

I'm not alone either. There are others on Apple's discussion boards with the same problem:
