This patch was originally created for Samsung Galaxy S II and Galaxy S III, but it might work for other devices* running Android 2.3 or 4.x because it patches the Email application that you have on your phone. This is not a pre-patched Email.apk.
* Motorola Blur (Droid), LG G2 and HTC Sense - based ROMs are not supported!
What does it do?
It will make the Email app ignore Exchange-pushed policy on your device, including things like mandatory pin lock (a.k.a. keyguard), minimum password length, encryption, etc.
How to apply this patch?
Root your phone. Your phone must be rooted. It is impossible to apply this patch without root access. You need root to proceed.
Get Java (Java SE JRE v7 or later)
Get USB ADB drivers (for Samsung, install Samsung USB Drivers). Most likely you already have this because of step 1.
Note - ADB via Wi-Fi is also supported. In that case no USB drivers are needed.
Enable USB debugging on the phone (Settings->Applications->Development->USB debugging)
* For CM9 users, also go to Settings > Developer Options > Root access, and select ADB.
Download and unzip attached patch
Run apply-patch.cmd or apply-patch.sh
Note 1: Although the Email app will prompt you for device admin access, it won't actually enforce any policy on your device. Let the app install the device admin!
Note 2: any shortcuts to the Email app as well as any Exchange accounts will disappear and will need to be re-created.
Note 3: The patch will reboot your phone, this is needed for the changes to take effect.
Note 4: If you already installed another Email application and it doesn't work, first restore your original Email application before applying this patch.
A Special Note to those experiencing performance issues! This is not an issue of my patch. This is an issue in the Email app itself. Sometimes calendar sync can't finish properly, causing battery drain. It often happens after you just added a new exchange account. A reboot usually solves this issue. Again, this is not my issue!

Already patch Email.apk
Your "How to install this patch "is a little to difficult for me.
Is it possible for you to supply an already patched Email.apk ?
In advance thanks
For those who are interested in the source code of this patch, here it is.
https://github.com/rustyx/email-policy-patch
Thanks you
I use the Email.apk with the how to you supply, and All work like a charm.
I want to thanks you very much.
Thank You
Thanks so much for your effort. just want to get one thing clear, since you provided the patched Email.apk can i just install it directly, or do i need to be in recovery mode for example. because in your note you mentioned not to install!
Thanks again
Root explorer will also work! no ADB required!
1) Put Email.apk on your sdcard
2) Go to /system/app and press mount rw
3) remove Email.apk and Email.odex
4) move Email.apk from /sdcard/ to /system/app/
Then you need to setup your email again!
I had to clear the data also in applications -> email
Edit1:
your Email.apk is weird. When i reboot i get the notification that i need to set extra security. But when i press it nothing happends.
And after the email.apk the phone doesn't feel as smooth.. weird
Edit: removed Email.apk (modified) and wen't back to stock! phone is smooth again and works fine
May I ask why u use const/16 ?
const/4 goes from -8 to 8 (2^4) and should be preferred for small constants I think

const/4 has also a limited range of destination register numbers, and with the p-format in smali the mapping of p-registers to actual v-registers depends on the number of v-registers. It may happen that in the future more v-register are added, and an existing p-register does not fit in const/4 anymore. Using const/16 is thus more or less future proof.
This is awesome, it woks great
I am on KF1 and it works flawless push with no lag or so
I wonder what happened when we deleted the Email.odex and didn't replace it? we only replace the Email.apk
At first to all, I used tool "FroyoMailUnlocker" to generate my new mail.apk and it worked fine for SGSII on 2.2.3 and also on GT7100 on Honeycomb 3.0.1.
Only problem is that after flashing new OS it need to be installed again.
Does anybody what settings should/can be saved to have an easier restore of the mailbox setup (for my exchange and hotmail accounts)?
Frank
This looks very interesting, but please help me figure out if it will solve my problem:
I have complete security enforced by my work Exchange account.
I need to sync email and calendar with that account.
I want to be able to set a timeout delay to the PIN lock engagement (now it is on immediately as the screen goes black), and it would be nice to use swipe unlock instead of PIN/password.
Will this hack do the trick for me? If so, even with calendar sync?
Thanks!
/Edit: I use the standard email app and calendar om my SGS2
too bad
Hi,
in general I was searching for a long while for this!!!!
Now I have all done as decribed and once I try to create the exchange account it comes back with: "the server requires security settings which your phone dosn't support"
too bad...any ideas?
update:
now it's working...I'd to be patient..
THANK YOU VERY MUCH!!!!
Just to clarify the instructions here (I am noob):
After installing Android SDK, do I unzip the attachement on my PC or phone?
The shell commands, I type them in the adb shell with the phone in recovery mode, or what?
Thanks!
I've been using this hacked app in the past week or so, and it does great what it is supposed to do.
BUT: lately I wanted to see what is draining the battery so fast, and imagine the surprise when I saw that the biggest drainer by far is email.apk, far above the display itself, which is supposed to be the main consumer!!!
Is anyone else seeing this? Do you know about any resolution to this? For now, I just froze the application, but that's not acceptable, since one of the main uses of the phone is to sync up mail, calendar, etc with the corporate one.

Do you have push enabled on the account? Try disabling it (setting it to a pull every 15 mins for example).
I had the same issue (without this hack though!) on one of my Exchange accounts, and not using push fixed the issue. It must be an Exchange provider issue, because my work account uses push with no issues.
I don't use push - I have it set for every 1h check during the workday and every 12h for off hours.
I even have disabled all notifications from it...

Hmm I see. Well, if this hack introduces another possible battery draining culprit, I'm not so sure I want to try it. I've spent too much time identifying battery draining apps/processes on my new phone already.
Has anyone else experienced email.apk battery drain after applying this hack?
Me. My phone also slowed down!
There are many factors that may cause a slowdown, which I have no way to reproduce. I can only say that my company's Exchange server is 2003 and that it is the only non-google mail account that I have configured on my phone. I have push enabled. The hack works great with this setup, i.e. no slowdown of the phone, no extra battery drain.
If someone who is experiencing issues can post more details about the version of exchange, sync mode, and any other pop/imap mail accounts configured, I may be able to investigate the issue further.

I am running your modded Email.apk in a Galaxy Tab with Gingerbread (Overcome Hermes) and I have no problems with slowdowns or battery drain either. However I am always getting a FC from the mail application when rebooting the Tab. Afterwards it works correctly. I guess it's natural since it is not the native mail application.
I have tried to mod myself the native Gingerbread Email.apk from the Galaxy Tab using your posted code, but it does not work (FC continuously). Although very similar to the Galaxy S II mail application, there must be some differences that make it impossible to just blindingly use your modifications.
Would you be so kind as to have a look at the original Email.apk from the Tab Gingerbread Overcome firmware and suggest a possible mod? Thanks in advance.
Hi,
Can someone please make a Mail.apk without the security policies for exchange servers?
I'm interested in one for stock 4.2.2 2.24.401.1
It was another thread where someone built one for 4.1 and custom firmwares but the developer stopped the support on that thread so therefore I'm opening this one.
someone in the thread made it, based off of 4.2.2:

Hi,
I am looking for HTC SENSE Mail.APK WITH exchange security to work on Google Play Edition ROM. I don't want to mess with exchange security override since I think it is unnecessary and will end up not working with my exchange policies. Does anyone have a stock mail.APK that they know works on the GE Rom?

I am running the GOOGLE EDITION Rom from this link http://forum.xda-developers.com/showthread.php?t=2358781.
I tried using some of the zips and APKs that I found on the forum.... I was able to successfully get past the first setup page where i entered the server details - which means that it is seeing the server and password etc. is accepted. But after that it fails to create the account giving the message "failed to create the account. please try again later." Now, I know this error is not because of my Exchange Server settings because i get this same app to work any any and all HTC Sense Roms.

no, they will not work, you've already made a thread, and replied twice in this thread and its pretty much off topic at this point.
the camera was ported since it the GPE has the sense framework for the camera. I highly doubt the GPE has the framework for the mail. I suggest installing http://forum.xda-developers.com/showthread.php?t=2356512

This ROM comes with an optional sense 5.5 exchange bypass mail.apk
I tried this out a few weeks back on a sense 5.5 ROM and it worked until I tried to reply to an email. I didn't try to troubleshoot the issue as I was just looking at the feasibility of running a 4.3 based ROM. I'm guessing you could get this to work.
Another option would be Enhanced Email on the playstore. I used that on my gs3 whenever I'd run AOSP ROM's, because I didn't have very good luck with the exchange bypassed native email app. I dunno if it's something about my work's exchange server settings or not, but it would still try to force security policies on my phone.
You can install Xposed and they have a module for Sense and AOSP to bypass Exchange Security. Easy to install, check it out.

I unzipped the entire archive and did a search for the Mail.apk file. I forget where it was located, but it's pretty straight forward.

OK, what is doing the hack to accomplish??? Exchange uses security features, so wouldn't that break functionality???

Trying to check my corporate exchange email w/i being forced to 'always key-in a PIN', encrypted drive etc. I'm OK for all other enforcements that come with the exchange sync (e.g. force data wipe etc). Looking for a convenience factor.
Makes sense?

Ah, OK, I see... Have seen some thing about bypassing PIN for corporate email a few months back. Will look for it again, when I have time Monday. I thought you were disabling it completely or something.
OK, I don't have a corporate setup with exchange so I cannot test.
My xposed module has a security option though it is not enabled and I have no way to test.
Here is a thread on another site... http://mobility.forumsee.com/a/m/s/p12-9290-072026--exchange-security-bypass-no-pin-android.html
I would just unzip the two files and side load them from SD, after doing a complete backup in TI Backup, and removing the two installs associated with the replacement apps.
This way no old settings or double apps will be created.
