Winmail.dat Received by Non-Exchange Mail Server Without Attachment Included from Exchange 2007 Server

August 7, 2008

Situation: Exchange 2007 has a contact (not a mailbox) within the GAL that end-user use to email instead of using the actual non-exchange email address. The non-exchange (network solutions) user does not get attachment sent (Word, Excel, etc.), but does get a winmail.dat file attached.

Fix: Launch Exchange Management Console, goto Recipient Configuration/Mail Contact container, open up contact you’re having the issue with, on the ‘general’ tab change the ‘Use MAPI rich text format’ drop-down to ‘Never’ and test.

Barcodes from Online Documents Don’t Print

September 12, 2007

Dynamically generated documents printed online may not print correctly if the settings for your printer print graphics in “Vector” format instead of “Raster” format.  Examples of this include airline boarding passes and shipping labels printed online.  To check and correct this setting, go to the Advanced tab in the printing preferences for your printer.  Sorry I cant put up step-by-step instructions as they very for each printer.  The only printer I’ve confirmed this on so far is an HP 1160.

There is a phishing attempt circulating that sends emails claiming to be from the Better Business Bureau.  The subject line is: “BBB Complaint for {Recipient Name} [Case id: #7dcd4491d93a6cd1f1ac30ad32b4d18d]”  The email that I’ve seen came from: “” although I’m sure there are many.  The email body looks like this:

Exchange 2007 Certificate Issues – Avoid them the easy way.

August 27, 2007

In most pre-Exchange 2007 organizations that were using OWA, a third-party cert for the public FQDN of your mail server was all you needed.  In Exchange 2007, things changed a bit and certificates play a much larger role in the organization.  One of the lingering issues I’ve seen was a certificate error internally saying that the certificate name did not match the name of the server.  This was because the certificate was a third-party issued cert using the public FQDN of the server and not the internal hostname of the server.  To avoid running into this issue any longer, I followed another article I found online and simply created a new forward lookup zone in the internal DNS for the public domain name of our organization (i.e.  In that forward lookup zone I created the host (A) record for the mail server and pointed it to the internal IP.  Next, following the article (see link below) I changed the links in Exchange 2007 so that they would reference the public FQDN even when working internally.  What this does is effectively use the same public FQDN for all transactions with the Exchange 2007 server so it will match your existing third-party cert.

E2K3 Public folder management – SSL certificate server name is incorrect error

August 24, 2007


I ran in to a problem where I was trying to remove a public folder store from a front-end server. The SSL certificate on the front-end server is wrong (wrong FQDN/CN, unknown CA, and it is expired). I could not manage the public folder hierarchy using Exchange System Manager.

Depending on what I was trying to do, I got this error:

The SSL certificate server name is incorrect.
ID no: c103b404 Exchange System Manager

I also saw this error:
The token supplied to the function is invalid
ID no 80090308

Lots of newsgroup and web discussion forms pointed to this KB article indicating that the problem might be related to SSL being required on the /ExAdmin virtual directory. “You receive an SSL Certificate error message when you view public folders in Exchange System Manager” I checked that and it was NOT the case.

Finally found some instructions in a newsgroup that worked. This requires ADSIEDIT and a little bit of Exchange configuration editing.

Navigate to the following object: CN=Configuration, then CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups, CN=First Administrative Group, CN=Servers, CN=Protocols, CN=HTTP, CN=1, CN=Exadmin
Display the properties of the CN=Exadmin object
Locate the msExchSecureBindings attribute, highlight it and click Edit button
If it has a value of :443:, select that value in the Values list, click Remove.
Click OK twice and then close ADSIEDIT
Give this a few minutes to replicate through Active Directory and try it again!

When you try to send an e-mail message in Microsoft Exchange 2000 Server or in Microsoft Exchange Server 2003, you cannot send the e-mail message. Additionally, you may receive one of the following error messages or one of the following Non Delivery Reports (NDRs):

• Access denied 

• You do not have sufficient permission to perform this operation on this object. See the folder contact or your system administrator. 

• Unlisted Message Error 

• MAPI_E_NO_ACCESS -2147024891 

• Failed to submit mail message for user USERNAME (HRESULT:-2147024891) Pausing user USERNAME. (Security error – Cannot access the users mailbox.)


• You do not have permission to send to this recipient. For assistance, contact your system administrator. 

• The message could not be sent using your mailbox. You do not have the permission to send the message on behalf of the specified user. 

This issue is known to affect the following third-party products:

• Research In Motion (RIM) Blackberry Enterprise Server (BES) 

• Good Technology GoodLink Wireless Messaging 



This issue may occur when one of the following conditions is true:

     You do not have permissions to send e-mail messages as the mailbox owner in the account that you are using to send the e-mail message.

     You are running Microsoft Exchange 2000 Server Service Pack 3 (SP3) with a Store.exe file version that is equal to or later than version 6619.4. Version 6619.4 was first made available in the following Microsoft Knowledge Base article:

915358 A hotfix is available to change the behavior of the Full Mailbox Access permission in Exchange 2000 Server

     You are running Microsoft Exchange Server 2003 Service Pack 1 (SP1) with a Store.exe file version that is equal to or later than version 7233.51. Version 7233.51 was first made available in the following Microsoft Knowledge Base article:

895949 “Send As” permission behavior change in Exchange 2003

Note that this fix is not included with Microsoft Exchange 2003 Service Pack 2 (SP2). If you have installed the Exchange Server 2003 SP1 version of this hotfix, you must install the Service Pack 2 version after you upgrade to Service Pack 2.

     You are running Exchange Server 2003 SP2 with a Store.exe file version that is equal to or later than version 7650.23. Version 7650.23 was first made available in the following Microsoft Knowledge Base article:

895949 “Send As” permission behavior change in Exchange 2003

Note This change was not included in Exchange 2000 Server SP3, in Exchange Server 2003 SP1, or in Exchange Server 2003 SP2. The change was implemented after release of all of these service packs. However, the change is supported in each of them. The change will be included in future service packs for these products.


If you install Exchange Server 2003 SP2, you must install the additional update to retain the new behavior. You must do this even if you already installed the version of the update for Exchange Server 2003 SP1.




Grant the Blackberry or other application’s service account the Send As permission on every user in a container or domain.

To grant Send As for the service account on a single user account, follow these steps:

1. Start the Active Directory Users and Computers management console.

2. On the View menu, make sure that the Advanced Features option is selected. If this option is not selected, the Security page will not be visible for domain and container objects.

3. View the properties of the user account and click the Security tab.

4. The service account (BESAdmin, for instance) is not listed.

5. Add the service account (BESAdmin, for instance). It will default to having Read permissions, but not Send As.

6. Note: This step is optional. The only permission the service account needs is Send As, so you can remove the Read permissions if you wish.  To do so, uncheck the following checkboxes in the Allow column for the service account (BESAdmin, for instance):


Read Account Restrictions

Read General Information

Read Group Membership

Read Logon Information

Read Personal Information

Read Phone and Mail Options

Read Public Information

Read Remote Access Information

Read Web Information


7. With the service account (BESAdmin, for instance) still selected, check the following box in the Allow column:

Send As

8. Click OK until you have exited and saved all changes. 

9. Restart the Microsoft Exchange Information Store service.
