OWA not working for Mailbox (MB) in remote location – Its all about the proxy!

One site, MB and CAS server all in one site. OWA worked with no issues.

Moved mailbox to another Site and OWA broke.

I had to change the settings on the remote location (MB Locations) for OWA:

Server configuration – > Client Access -> go to the server in question (the MB server) -> OWA (Default Web Site) -> Authentication -> change to “Integrated Windows Authentication” and on general tab, set external URL to nothing.



Outlook 2010 always saying “Contacting Server for Information”

Microsoft says that Outlook freezes “by design” and that they are not going to be working on this issue. Below is their explaination and proposed solutions:

Issue Statement:

Outlook contacting server for information when replying/forwarding and printing emails with HTML contents and images.
The behavior that we are experiencing is expected when we have Outlook 2007 and above which does not cache message references (hyperlinked images in our case). Reason behind this is an expected behavior is Outlook 2007 and above versions do not keep the reference data of message/email body. The time it points to references data from specific location which is mentioned in hyperlink, which is nothing but advanced HTML content which renders based hyperlink. Unless the entire content is downloaded Outlook.exe will wait, once entire content is fetched in email Outlook.exe process will respond back. So the hang that is experienced is moreover an expected behavior when we have such advanced HTML content. This behavior with advanced HTML content is known to Microsoft since product is designed to wait until the content is loaded 100%.


Outlook contacting server for information when replying/forwarding/printing emails with HTML content.


This is a known issue when you are dealing with HTML emails which have the images on a different server and are not embedded images.

When you open HTML emails which have images that are stored on another server Outlook will contact the server to download the images every time you open the Email. It won’t save it locally as the image is not a content of the Email. The emails only have links of the images which is actually on another server.

So when you forward or print Outlook will contact the server once again which ultimately will take some time to download the images.

In Outlook 2010, default and the only rendering engine is Word, and since Word is not a browser each image is considered separate from any other (a unique link). This is unlike a web browser which treats images like a pool of resources and will reuse the same one over and over if two tags share the same link path. So whereas a browser only needs to pull the image once, word will pull it for every image. In addition, word don’t guarantee rendering of content designed for web pages and not email.

Reading the email is OK because we can download images in the background (it is a synch). But to forward or print, we have to pull the images synchronously because we need the download to complete before we can proceed to the next step. So the reason it only occurs on those steps is by design.


This is a by design issue.
We have listed a few workarounds below:-


Uncheck the option in Trust Centre “Don’t download pictures automatically in HTML e-mail messages or RSS items.” which you have already tried and it is working for some emails but not all.
You may create a Registry Key as mentioned below which gives you the same behavior as the first step:


Dword: BlockHTTPImages

Value: 1

You can open the Email in Web Browser by opening the Email and going to Actions -> View in Browser.
In Outlook 2010, under File tab, Options, locate: Replies and forwards: there is the option of four ways of forwarding email:


File -> Options -> Trust Center -> Trust Center Settings -> un-tick the ” Don’t download pictures automatically in HTML e-mail messages or RSS items.

Set the default addres book for a user in Outlook

Have you ever wondered how to change the default address book in Outlook when you are using Exchange. If you have ever sent an email and tried to find your contacts using the To: button you know that by default the Exchange Global Address Book is the first source of contacts. What a pain.

I always find it difficult to locate where to change the default so I thought I would post it in case you are looking. I know I will come back to this post because even after having found it, I still can’t remember how to do it. It is just one of those things that has never been intuitive.

Here are the steps:

  1. From Outlook 2010.
  2. Select Contacts in the navigation pane,
  3. Ensure the Home tab is selected.
  4. Select Address Book from the ribbon.
  5. The Address Book: Global Address List windows will open
    1. Select the Tools Menu
    2. Select Options
    3. The Addressing Window will open
      1. Choose Start with contact folders
      2. Select OK
    4. Close the Address Book: Global Address List  window

From now on when you click the To: button your default address list will be the outlook contacts folder. If you don’t remember how to do it in the future, remember you found it here. I know I will be back to this post the next time I have to do this

Outlook continually asking for username and password

My sysadmin has been bugging me about this for months. Two or three users have been bitching about Outlook (2007 with an Exchange 2003 backend) asking for the username and password over and over again.

My sysadmin is now on leave and the MD is having the issue. Time to start looking into it. After a couple of hours searching on the web, I came across this article.

Go to – Control Panel – User accounts – Advanced – Manage Passwords

In here i could see my sysadmin’s accounts credentials against the mail server in questions from a couple of months ago. I clicked “Remove from Vault”. Issue fixed.

Should stop my Sysadmin bitching for now.
