Activesync - account verifies but is unable to view email

Hi, I've been struggling with this issue today and cannot workout why or what is causing it. The symptoms are:

- Activesync verifies on the idevice
- No email is displayed in any folders
- Mailbox folder structure is downloaded and can be viewed, but no emails are in there.
- I can send email
- Testing the server Acessmylan's Activesync tester and it passes
- The occasional event id 3005 is logged - http status code 503

I have followed and read the article posted here:
https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_1798-Exchange-2003-Activesync-Connection-Problems-FAQ.html

Does anyone else have any suggestions?

I would mention this is all working without SSL (well it used to work!) and I've already cleared IIS and had Exchange System Attendant rebuild it.

Well if my article can't help you.....................

Okay - so why are you not using SSL?  You will be sending your usernames and passwords across the internet in plain text (can be easily intercepted)

Is Exchange 2003 part of SBS 2003 or standalone?

If the folder structure is showing, that suggests that things should be working.  Are you setting the idevice to show more than 3 days so that mail will show up, or is there mail within the last 3 days that should show up but doesn't?

Hi Alan,

Thanks for your response!
I've not set it up to use SSL just yet as we've had 'quirks' like this - throwing SSL into the mix in the past has always proven an issue when it comes to troubleshooting.

It's Exchange 2003 SP2 on a standalone 2003 SP2 server.

It's currently set to 3 days and yes there should be email showing up.

Okay - without SSL you can't test properly on https://testexchangeconnectivity.com

It might just be a case of updating MASSYNC.dll via KB967046 (which is a call Microsoft or I'll send you a download link option).

Can you right-click and Browse the Exchange Virtual Directory in IIS Manager?  If you do - what do you see?

What Anti-Virus software is installed on your Exchange Server?
If you could send me a download link that would be great (hate being on hold!).

Right-click and I can view OWA as you would expect, apologies if you meant another virtual directory.

AV currently installed is MSE.

Without questioning your judgement (I am uninstalling MSE) Can I ask how you know MSE can break activesync? And what about activesync it breaks? I'm just interested to learn the reason behind it, or has it been a common factor in other situations you've assisted in?

Regarding MasSync.dll the version on the server is 6.5.7638.1 - just below the version advised in that KB article.

I've just looked at the device and after removing MSE it looks to have done the trick already!
Check my blog:

"RECENT UPDATE (29/05/12) – Please make sure that the server does not have Microsoft Security Essentials installed as this will break Activesync.  If you find it is installed – please uninstall it."

Blog is easier to update than EE as I need PE approval to get modifications added whereas my blog only needs me to hit the Update button :)

Glad you are sorted - you did look 99.9999999999% there.

Now get SSL installed - PLEASE.
