Outlook 2010: HTML email not completely showing content

Problem:  When I receive an email, sometimes I cannot see the entire content of that email.  It’s cut off in the middle.   I can read the entire email in OWA or the “view source” or “view in browser” option within Outlook but not within the native view within.   The only thing that I can think of is that it’s a security issue because it seems like it happens with automated email like password resets and such.
Note:  If I forward the email to myself in OWA, I can see it in Outlook.  I also tried in outlook 2011 on my Mac and was able to read the whole email.

Solution:  Within Outlook 2010, go to option and the Trust Center.  There click on Email Security and check the “Read all standard mail in plain text” option.

This isn’t a solution, really a work around but it’s a start.  Does anyone have an idea or two?  Thanks!


Windows 2008 R2: DCDIAG replication error

Problem:  When running DCDIAG on my Server 2008 domain controller, I get the following error:

(DC name): This replication path was preempted by higher priority work
from DC1 to DC2
Reason: The operation completed successfully
The last success occurred at (never)”

I tried DCDIAG /fix without any luck and ran DCDIAG on my other DC’s  and didn’t get the error. 

Solution:  I went into Active Directory Sites and Services and checked the NTDS settings of the two Domain Controllers named in the error.  Turns out that “DC2” was set to replicate with a DC that was no longer on my network.   Changed the replication to the proper DC, waited about 30 min and the error was gone from DCDIAG.


Java freezing chrome and crashing

imageProblem:  When accessing a website that requires the use of a Java Applet, Chrome freezes and eventually will crash.  If I upgrade to Version 7x, the program works just fine.  The problem in this solution is that the computer needs to use Java 6 for a program that will only work with that version of Java and will not function at all with the latest version.  The good news is that this new website is supposed to work with Java 6.  So why is it freezing?

Solution:   After trying to uninstall Java 6 and reinstalling (which didn’t work), I tried installing the latest version of Java, uninstalling it and then installing Java 6.  That worked!  Why?  I haven’t a clue.  Perhaps the Java 7 install reset some settings that didn’t happen in my Java 6 reinstall try.   Ahh!  The joys of Java.


Emails are delayed or fail from bigfish.com

PROBLEM:  When a user tries to send my organization an email, they will get an error message stating the the email has been delayed.  The exact message: “This message hasn’t been delivered yet. Delivery will continue to be attempted.”

After a few days, the user would get an error that the message has failed stating that the “Delivery has failed to these recipients or groups”

The frustrating part of this issue is that it doesn’t happen consistently.  The emails will successfully be delivered for days or even weeks and then the errors will rear their ugly heads once again.

Observations and what I have done to troubleshoot the issue:

  1. In all of the failed emails, the generating server was from the domain bigfish.com.  After a couple of google searches, I found out that this is part of the Office365 services.  In particular, the Forefront portion of the service.
  2. I whitelisted the email of the sender in our spam filter to make sure it wasn’t getting blocked on accident.  This did not fix our issue.  (our spam filter is a Mail Foundry appliance).
  3. I removed some outdated blacklist sites on the spam filter to improve SMTP response time.  Did not fix
  4. I put our spam filter in a DMZ to rule out our firewall.  Did not fix
  5. Per a suggestion from a fellow admin, I checked our DNS and made sure that our SPF record was setup setup properly.  Did not fix
  6. Worked with Mail Foundry tech support and confirmed with them that the email wasn’t even getting to the appliance, let alone rejecting the message.
  7. Changed ISPs.  We switched out ISP’s not because of this issue but just to change service and this didn’t fix the issue as well.

I have tried everything that I could think of so now I turn to anyone who might stumble on this post.  Hopefully, someone might be able to give me a suggest that I haven’t thought of yet.  So if you have a suggestion, please leave a comment.


UPDATE 4.13.14:  After working with another engineer who was working with Microsoft Forefront’s tech support, we found out that my firewall was blocking some of the originating servers.  This would explain why some mails would go through and some wouldn’t.  We had some Geographic/country related rules to block unwanted traffic.  Problem is that MS has servers all over the world.  So I created a white list for all the IP’s that Forefront uses(see below).  Once we did that, email seems to be passing much better.

Forefront IP ranges to white list:
