If you can send messages to other domains and only have problems with army.mil, the most likely reason is that army.mil has some policy that block the messages sent by your domain.

  1. Firstly you could check if your domain has valid SPF recordvalid DKIM domain keys, and valid dMarc settings.
  2. Check if our firewall block the messages.
  3. Since you didn’t find any error on our side via message trace, you could let the admin from army.mil check if our message hit their mail system. Also check if there is any policy or rule block the message in firewall. If yes, they can add our domain into their allow list.

Solution 40-1: If you have MalWare Bytes (MB) installed, it is blocking the VBScript from allowing you to send an email via OWA. You can right click it and close the program to see if this is what is causing your issue. If that doesn't work, try Solution 40-2 below. Solution 40-2: Open Settings, Protection (tab), Advanced Settings (button), Under the Application Hardening (tab), Uncheck Disable Internet Explorer VB Scripting (under the Browsers heading), click Apply ... : an Army Reserve [or National Guard] Soldier who is also a DoD civilian [or contractor] and is authorized [or required] to have / carry / use two separate CACs.

As issue ridden as the Army's Enterprise Webmail is I would like some guidance as to how fix a certain problem. Every time I try to log into the webmail I'm greeted with this same problem.

image

All other sites work (myPay, AKO, ALMs). This is the only one giving me an issue. Also I have used militarycac.com, it hasn't changed anything.

Edit: 10/30/14

SOLUTION: Get your CAC replaced. If that doesn't solve your problems on IE, then follow the advice below.

If you are constantly getting an Error 500 "page cannot be displayed", try downgrading from IE11 to 10. If you don't know how to do this then you go to Start--->Control Panel--->Uninstall a Program--->View Installed Updates--->scroll down to Microsoft Windows--->delete Windows Internet Explorer 11.

Also use the link: https://web-mont01.mail.mil

How can I get access to my Army email? I’m scheduled for BLC soon and I was told I can’t go without it. Nobody in my unit can help me because of the shutdown and my last two BAs were cancelled. Is this something I can do at home?
