Hi, my first post here but a long time Windows Phone user. My universitiy has an Exchange 2003 server and it works fine but when I plug in the settings into my Tilt 2, and then I walk into a building that prevents my phone from getting reception, the phone asks me to reenter my password even though it is already saved. My wife has an iphone 3g and it is accessing the same exchange server and her phone never asks her to reenter the password when she goes into a building. what is going on here? Is there a way to prevent it from asking for my password even though it is already saved?

P.S.- technically when this occurs i don't have to retype the password. When it asks me for my password I press cancel to close out activesync, and then I start it up again and the green activesync icon is actually orange. Then I press Sync, and it starts to sync until the activesync button turns green again. This is all quite annoying. I have this phone for its push email but it is not solid. and I really dont' feel like giong to blackberry just to get reliable push email when I know windows phone can do it. 

Welcome, doctagadget - This sounds very annoying! I haven't heard of this specific issue, but there may be other members here who have direct experience with this phone. Can we assume you're on AT&T with the Tilt 2?

 yep AT&T

Okay, doctagadget, I had to work hard to remember this, but way back when we first started this forum, we figured out there was an issue with the way AT&T WM phones handle the carrier's data proxy connection. The problem is that sometimes the data connection "times out" and needs to be refreshed with a new request - affecting Web browsing, Exchange ActiveSync, and other data services. This could explain why you have to restart ActiveSync to reload the Exchange connection. The answer we received from the Windows Mobile internal team is below. You should be able to follow the procedure by going to Settings > Connections > Connections as well...

"The issue is with the proxies that AT&T uses... In IE, under Menu > Tools > Options > Connections, set the network to INTERNET, un-checking 'Automatically detect..' and this will bypass the proxy. This works 100% of the time unless there is something else going on with radio but that would be unrelated to this issue.

 

Brief issue summary: The WAP Proxy (MAC) is designed to ensure that devices have active data connections for less than 24 hours. If the device exceeds this time, the gateway rejects the outbound request with a 403 – Access Forbidden. This is for legacy devices that did not normally maintain always-on connections such as smart devices. So, with our always-on presence we exceed this timer restriction and are denied outbound access.

 

Changing the pathing to INTERNET instead of WAP works around this."

Something else to check for would be in the Tools folder - some AT&T phones have an application that allows you to disable the proxy directly. This should achieve the same thing.

I stumbled upon this thread while doing a google search.  I am  having the exact same issue with with my work exchange sync.  It works fine, but every so often it comes up asking me to re-enter my password.  I can do the same thing and just hit cancel and then sync and sure enough it syncs right back up.

 I however, am on Sprint's network not AT&T.  I tried to see if any of the setting you mentioned were on my phone and they are not.  I am using the Touch Pro 2 (WM) now.  I have had 4 different windows mobile phones on Sprint's network and they all have done this to me. 

Thanks in advance for the help!

Sorry to hear you're having the same issue, Blitzed26. I wish I could be of more help.

One thing to consider: Jason Dunn of Windows Phone Thoughts  just posted something interesting on his personal blog. It suggests there could be an issue with the way the Exchange Server was configured for mobile access:

A couple of weeks ago, I moved the remainder of my sites ..., and among them was my wife’s domain. This domain is connected to a hosted Exchange account ... , and part of the move was setting up a the autodiscovery domain so Outlook can self-configure. After the DNS changes were made, something strange started happening with Outlook on both my wife’s desktop and netbook: it would repeatedly prompt for the password. No password changes were made, and strangely enough, she could send and receive email even though every few minutes it would prompt her for the password. ... After some sleuthing around, convinced that it was related to the DNS changes I made, I realized my mistake: I had created the autodiscover CNAME entry pointing at the wrong server name (EXCH016 instead of EXCH015). After updating the DNS record, within a few hours the problem was fixed – no more repeated password prompts in Outlook.

No idea if this is any help at all, but if you can easily get in touch with your Exchange admin, it might be worth a quick check.

Thanks for the response.  It appears however, that the quote you put in there is referring to his laptop and netbook..  I don't have that issue at all with connecting via my laptop.  So you think that could still be the issue with my phone constantly asking for the password?

Arg, sorry about that! If your laptop connects normally, then no - it sounds as if it's not that particular server issue.

I would still suspect either something in the way the data connection is being handled on Sprint's network (as in the AT&T situation), or some other configuration or time-out issue coming from the Exchange Server side. 

Again, if you're able to request help from the Exchange admin, he or she would likely have a much better idea than I about this one. Sorry!
