Microsoft Direct Push
aka
Microsoft Push Email for Windows Mobile 5 Device with AKU2

Read Configuring Push Mail from TrendsMobile
Read Direct Push is just a heartbeat away from Microsoft to understand it from Microsoft Exchange point of view.

Now my personal findings/compilations:

1. It is not ‘Push’ at all. It is smart poll. It opens GPRS/3G data connection and keeps it open all the time. Because GPRS/3G module consume additional power, your battery will be flat bit faster. (BTW, 3G consumes much more then GPRS)

2. It has a bug:)
When first synchronization starts, it must be from GPRS/3G connection of mobile device!
If not, your GPRS/3G will be kept connected, but no email
To check go to (on mobile device) Programs -> ActiveSync -> Menu -> Status
Must be ‘Result: Synchronized‘ (and check ‘Last synchronized:’ and ‘Last attempt:’)
If you have errors, simply reboot your device.

To avoid it, configure Push Email first time from mobile device with USB DISCONNECTED and NO WIFI!

2. Your data traffic will depend on your mobile device settings, Microsoft Exchange Server settings and volume of your mail. You, probably, may change only your device settings. Default setting with mail2web service on my Dopod 900 (QTEK 1.30 ROM) consume about 25 (20..30) kB per hour (will explain later, why per hour)

Change registry value under
HKCU\Software\Microsoft\ActiveSync

MinHeartbeat=1200 (default is 480, i.e. 8 minutes)
InitHeartbeat=1200 (default is 480)
Max Heartbeat=1800 (default is 1680)

Thus, I set minimum/initial heartbeat to 20 minutes (from 8) and maximum to 30 (from 28, where 30 is default Exchange maximum). With this setting I have 12Kb per hour (more than 2 times less!)

It works very well on my Dopod900 with mail2web free Exchange service.

4. When configuring Push Email (Programs -> ActiveSync -> Menu -> Schedule) set
Peak times: As item arrive (<- it means Push Email)
Off-peak times: Manually (<- it means when you connect USB cable or press ‘Send/Revive Mail’ while on WiFi)
and set desired peak times (for ex, 9 a.m.-6 p.m. Mon-Fri)
Thus you will save a lot of traffic by not sending and receiving data at night.

Can't edit it :confused:
Insted of
(from 28, where 30 is default Exchange maximum)
must be
(from 28, where 45 is default Exchange maximum, 59 - hard coded maximum)

you may try to use MaxHeartbeat=2700

Hi everyone,

Mail2web

I tried this service and configured my activesync as instructed.

1. My emails get forwarded correctly to this account.

2. My emails get "pushed" to my Dopod 900 when I am connected via USB activesync.

3. My emails get "pushed" when I am on wi-fi too. (Sorry Riv...it works on wi-fi)

Here is where my problems start:

1. I can't get my emails pushed on GPRS (strange but true!)

2. I then couldn't even access the internet via GPRS (again! strange)

3. the U icon (3G) became the U with the GPRS connection icon even tho' I can't get connected!

4. I also DON'T KNOW WHERE to control the timing of the "pulling"

5. I also DON'T KNOW what the email button on the Comms Manager is for.

Hi Vladimir,

how do you measure your data transfer? GPRS Monitor? I am wondering why my volume is so much different from yours.

I am using 'Direct Push' on an Atom. Used GPRS monitor to check the transfer volume over night when no e-mail etc was expected. My hourly volume is only 6kb with the standard heartbeat settings. I consider this still high as it comes up to 4MB/month without actually transferring any exchange data.

Strangely, the rate is even less (3kb/hour) when I am overseas :confused:

any idea whether location is influenzing the volume???


(not using mail2web but my own exchange server)

I used GPRS monitor.
GPRS - Singtel (Singapore).

Locations should not influence on data traffic, but using your own server (not mail2web) is important.
For your own server you can change SERVER SETTINGS of size of heartbeat and default heartbeat interval (see MS article).

Hi everyone, I was trying to find the URL to download this Push Mail, can anyone tell me where to do so? I hv being searching but couldn't find

Appreciate.

Hi getzsteady,

there is nothing to download. This thread is about the built-in Direct Push between a device with the AKU2 update and an Exchange Server.

Hi finally got it done! Great tools especially for me on the road always.

Hv tested it out and found the following requesting someone to help to answer,

- When I am on WiFi (Not Sync with PC) i.e. running within my home network Wireless Router, The mail don't come in through Wifi, instead the GPRS automatically turn on and mail2web deliver the mail. Why is this so and how to have the setting auto detecting which is online in order to prevent too much access via GPRS.

- When after downloading of the "Push Mail" from mail2web, how come it doesn't disconnect by itself automatically. How do you create that setting to disconnect each time after downloading.

Many thanks in advance.!
