Having a strange problem with Outlook / Exchange 2010 here that I hope someone can help me through.
I have outlook set up on a number of company laptops, using outlook anywhere so that they work both inside and outside the corporate LAN.
on the internal LAN everything works fine, externally however Outlook refuses to connect, continually displaying a pop-up box asking for the username and password.... putting those in doesn't do anything, the message just re-appears.
After much testing, I have discovered that if I navigate within outlook to
accounts / more settings / connections tab / exchange proxy settings button
There's a section entitled connection settings - this is populated with the following
there's then a tick in the box saying "only connect to proxy servers that have.........
if I change the first box to https://mail.domain.com
and remove the tick from the second box then everything works externally.
However, the moment the machines are plugged back into the LAN, the original settings re-populate.
This tells me it's something to do with the autodiscover file..... but I don't know exchange well enough to fiddle.
Can someone either help me sort the problem, or disable autodiscover somehow as (to my knowledge) we don;t actually need autodiscover to work.
