[CAB] Enable Active Sync with Multiple Exchange Servers

---

Eyup,

This is not my fix, I found it here all credit to Nuno Luz of MSMVPs.com - who in turn found it from "Chris de Herrera" here. (That's as far as I traced the credits )

Basically in Active Sync 4.* Microsoft removed the ability to Sync with 2 Exchange Servers.

I tested this fix on my phone with the following setup:

• Active Sync via USB with Work's Exchange (no E-Mail)
• Active Sync via USB to Home Outlook (no E-Mail)
• Active Sync OTA to Google Apps Mail (inc. E-Mail)

Changing the following registry setting will allow it to work with 2 servers.

Tweaks (in many formats)
Changing the follow registry DWORD to 1 will enable it:

[HKEY_CURRENT_USER\Software\Microsoft\ActiveSync\EnableNonLocalCrossPollination]

Here's the Prov XML for anyone who's interested to use:

<!--Enable Multiple Exchange Servers -->
<characteristic type="HKCU\Software\Microsoft\ActiveSync">
  <parm name="EnableNonLocalCrossPollination" value="1" datatype="integer"/> 
</characteristic>

And finally, here's a CAB: Download

P.S. I would recommend soft reset after installation.

EDIT: If I'm not the first to post it on here, then I couldn't find it. Let me know if someone else has, and I'll make this thread disappear .

Thanks,
Dave

awesome stuff, thx

To say it first: Great finding!!!

But i can't get it ...
Do i have to set up one Exchange Server on my PC's ActiveSync and the other on my WinMo's ActiveSync.
Or is there a possibility to add one Exchange Server to my WinMo's ActiveSync?
And if there is one ... how can it be done?

regards

I set mine up by syncing with my Work's active sync via USB, and then launching Active Sync on the Phone and doing "Menu" > "Configure Server".

You say you can sync email with multiple exchange servers with this?
I can't find any way to setup the second exchange account when you already have an exchange account setup.

I do not want to sync through USB, I want it to be possible through 3G / WiFi for both.
What I want is to sync 2 email boxes on 1 Exchange Server. Basically my own email box and an info box. This can also be done of course by just adding the same server twice, just with different credentials. However I can't find a way to setup a second exchange server when you already have one set.

You sync email with only 1 account. Syncing different items with more than one PC / Server was already possible without this fix.

-edit- I'm not sure if it is coincidence or not, but syncing exchange through 3G stopped working after applying the CAB file, syncing through WiFi on same network did still work. After undoing it and soft reset it worked again...

No he is not saying this. He only said email at the last item of Google Apps Mail.

This only lets you sync multiple non-mail items with different Exchange servers. Once you pick email, it locks out the Exchange choice again.

PS: I really do need a way to sync two exchange email accounts.

As do I, guess we'll have to wait for WP7

I just set up two exchange accounts and then tried RapiConfig to get settings.

Got error: Config failed <0x85070006>

Anyone have some of the settings information from

<wap-provisioningdoc>
      <characteristic-query type="Sync" recursive="true"/>
</wap-provisioningdoc>

Can't really get it working.

On the Phone
- Phone Disabled in ComMgr
- Wifi disabled
- Installed the cab => OK
- Checked the Regkey => OK
- Softreset my HD => OK
- Rechecked the Regkey => OK
- No ActiveSync Settings configured

Phone connected to PC via USB
- Configured ActiveSync on my PC with nuevasync.com to have multiple Calenders from GCal and my Contacts as described at www.nuevasync.com
- Synced via USB => OK
- Disconnected Phone from PC

Back to the phone
- Start ActiveSync (not the syncing)
- Go to Menu => Configure Server
- Set up Email address (unchecked "Attempt to detect ExchangeServer Settings automatically"
- Set up Server adress to m.google.com (checked "This server requires an encryted (SSL) connection)
- Set up user information as described at http://www.google.com/support/mobile...36&topic=14299
- The dialog "Choose the content you want to synchronize" is empty

Where am i mistaking???
Can someone please help me?

Thanks in advance

If the last thing your are trying to do is set up exchange email, try going into mail acount instead of activesync. Do not let it try connecting and instead select type as exchange.
