Yet another great reason to Jailbreak your device. Normally Apple only allows one Exchange server to be used on the device, but now with MultiExchange this restriction is removed and you can add and sync with how many servers you want.
Exchange server also allows you to do Push Mail just like with Yahoo accounts. You can even sync / push your gmail accounts:

When syncing with more then 1 server you have the builtin option to sync the data into it’s own group instead of merging it with the iPhone database, in order to avoid conflicts.
Please notice that while this has been tested to work OK with some servers, your millage may vary according to how Apple supports this.

How does this work with the calendar? What happens if you setup 2 calendars using Exchange to push contacts? Can you switch between them?

If you select “Keep on my iPhone” when you sync anything, it will create a seperate group, so in contacts / calendar / email you will have a new group for each of the accounts.

I’m also curious how this will react with AddExchange. I would think it best to remove AddExchange first then install MultiExchange..thoughts?
Thanks!

I think that if you remove your account with AddExchange it should revert to a backup copy of the .plist Afterwards your system should be back to the normal seetings (and you should move to MultiExchange which works in a safer way).
Altough there should be no reason for both of the programs to live / work together (for those inclined).

now if someone could just figure out how to rearrange the mail accounts. no matter how i ordered the accounts in the plist, i still can’t get them how i want :(

Works pretty well for the most part. But once I add 3 or more exchange accounts the phone is sluggish, runs hot and drains the battery abnormally. This occurs even if all but one are set to manual retrieval.
I also notice that only Exchange 2007 works, I think I used to be able to use 2003 when it was the only one.
My iPhone is a 16gb 3G with 3.1.2, jailbroken with pwnage.

Let me correct the above. What didn’t work yesterday, my Exchange 2003 connections, works today. Go figure.

This is ALMOST what I need. However, I really need to be able to sync two Exchange servers on my home desktop.
Our company just turned off access to the Exchange server from iPhones so I had to get a POS blackberry (hate it).
However, I have a personal exchange server as well. So what I’d like to do is have my home computer accessying and sync both servers, and I’ll just have my iPhone sync with my home one (which would be sync’ed with the work one).
PLEASE HELP. Is there any way I can do this? Or any other ideas?
Are there any services that do something similar?

Only solution I know of for that, if you’re using Outlook, is to set one of them up as IMAP. MultiExchange for Outlook would be a great idea.

Outlook 2010 will support multiple accounts. Get yourself a beta/RC or wait a few months for it to RTM.

Added the MultiExchange but it does not work.
At least not with Exchange 2010.
Not sure if this is an apple or bigboss problem.
The first account (default) is synced to an exchange 2007 – and it works fine.
I added a second account to a different exchange 2010. Now it does verify OK, however when I go to email and select the account I get an error message: failed to connect to server.
Also noticed that when I remove an account it removes it from the settings- but not from the email app. (this is secondary, I first wish I can make it work).
