Only One Remote PC Cannot Access Exchange via OWA or via Outlook RRS feed

  • Question

  • This is driving me crazy here.  Our company has a hosted exchange server (which I have no access to).  Right now, it seems to be working fine for everyone.  Users can connect from both inside and outside our office networks, via both outlook and via OWA.  However I have one remote user (working from home) that cannot access their exchange email at all.  Outlook no longer connects and if I try to access OWA the request times out and I'm never even asked to log in.  Thankfully I have access to this person's PC via teamviewer.  As far as I know, nothing has changed on the PC or with their internet that would cause this.

    Thus far I've set DNS to google and flushed it, I've turned off the firewall, reset the clock, added owa to the safe sites list, turned down the IE security level, and generally tried everything I can think of.  Even more odd, I tried using a free proxy (hidemyass) and I get to the Authorization Required screen of OWA, but I can't successfully login as that user or as myself. Via the proxy I've tried every variation on domain\user name, but I can't login.  Both logins work fine both here at the office and remotely from my home internet.  The trouble PC in question has no problems connecting to any other websites as far as I can tell.

    I've looked through their home router and everything remains at it's default.  The exchange email server has ping disabled, but the IP that the trouble PC gets is the same I get from anywhere else.  I'm not sure what else it could be, but I imagine that if I can get it to connect to OWA then outlook will work.  Thanks

  • Have you tried connecting her computer from a different network?  That would help determine whether it's her computer or home network.

  • Hi,

    We can follow ED’s suggestion to check whether the problematic user also can’t access her mailbox in other computers.

    Please also check whether she can login to OWA in other domain computers. If the issue happens to all computers and this user can only access her mailbox in her owned domain computer, we can contact your AD administrator to check whether the user is set to log on to specific computers:

    1. Open Active Directory Users can Computers as a domain administrator.

    2. Click Users. Right-click the problematic user > Properties.

    3. In the Account tab, click Log On To.

    4. In the Logon Workstations window, please make sure All computers is checked.

    Thanks,

  • Maybe it's because OWA and Outlook (if it uses EWS) use https, and all the other sites you visit (i.e. everything else that works) only uses http. It's unusual for https not to work when http does, but maybe it is switched off in the browser options, or even broken or firewalled.

    Can the PC access any other site using https? Google likes to use https now, so that would be an easy one to try.
