Cannot connect to Exchange webmail via Orange 3G PCMCIA card

Hi there - If anyone can offer any assistance or ideas about this I
would be really grateful.

Exchange webmail is running fine on my companies network. Users are
connecting from home, from wifi hotspots on laptops, and all over the
place.

However, for those times where wifi is unavailable, I've bought an
Orange 3G data card for my laptop. It works fine, and is often pretty
quick - Only for some reason it won't connect to our Exchange webmail.
When I try to connect it asks me for my username and password as
normal, but it keeps asking me. After 3 or 4 tries it gives me the
"access denied" screen.

as soon as I turn off the 3g card and connect back onto a wireless
network, I can connect again. What's going on?! Any help or ideas
would be amazing! Thanks!

Which Exchange - 2000 or 2003? Plain or SSL?

I used to have a similar problem which I seem to recall was related to
speed and security packets arriving in a non-timely fashion.

Hi there,

Sorry - Exchange 2003. I'm not sure if it's plain or SSL. I imagine
it's plain.

Thanks

OK, don't have a specific answer then - just connected to our 2003
webmail over SSL from Vodafone 3G and it is fine - in fact faster than ever!

Are you able to test to other webmail based services?

Have Orange enabled the card fully - for example VPN - at one time they
offered two services on their 3G card.

Have you got a copy of outlook 2003, if so then connecting to exchange
using RPC (this is new for this version of outlook and exchange) and
see if that works. Certainly in my shop there have been reports of this
working much better over 3G cards than the previous VPN solution,
Details of how to connect can be found at the link below, or talk to
