Rollup 1 for Exchange Server 2010 SP3 – Released

Again our Exchange CXP team released Update Rollup 1 for Exchange Server 2010 SP3 to the Download Center.

A known issue with Exchange 2010 SP3 RU1 Setup

You cannot install or uninstall Update Rollup 1 for Exchange Server 2010 SP3 on the double-byte character set (DBCS) version of Windows Server 2012 if the language preference for non-Unicode programs is set to the default language. To work around this issue, you must first change this setting. To do this, follow these steps:

  1. In Control Panel, open the Clock, Region and Language item, and then click Region.
  2. Click the Administrative tab.
  3. In the Language for non-Unicode programs area, click Change system locale.
  4. On the Current system locale list, click English (United States), and then click OK.

After you successfully install or uninstall Update Rollup 1, revert this language setting, as appropriate.

Exchange team is planning to resolve it in a future rollup, but did not want to further delay the release of RU1.

Microsoft Exchange Connectivity Analyzer Tool – Client

The Microsoft Connectivity Analyzer Tool is a downloadable client program that is used to identify connectivity issues that occur between email clients and a server that is running Microsoft Exchange Server. The tool can also be used to identify connectivity issues between email clients and Office 365. The tool can be used both by email users, to identify common problems, and by IT Administrators, to troubleshoot issues that are affecting their Exchange Server deployments.

The Microsoft Connectivity Analyzer Tool simulates several client logon and mail flow scenarios. When a test fails, many of the errors message provide troubleshooting tips to help the user or IT Administrator to resolve the problem.

This tool is a companion tool to the Remote Connectivity Analyzer website. Whereas the Remote Connectivity Analyzer website enables IT Administrators to pinpoint connectivity issues by simulating connectivity from a location outside the customer environment, the Microsoft Connectivity Analyzer Tool lets both email users and IT administrators run the same tests within the user’s environment.

You must be running one of the following operating systems:

  • Windows 8
  • Windows 7
  • Windows Server 2008
  • 64-bit edition of Windows Vista

Download the client tool (Microsoft Connectivity Analyzer (Beta) here.

Connectivity check as follows




Select one of the option below to continue to next screen


Enter the credential you want to check for connectivity issues

Remote Connectivity Analyzer gets an updated CAPTCHA experience

The improvements to the Remote Connectivity Analyzer CAPTCHA experience. It was very annoying to have both password fields get blanked out if you got the challenge incorrect. While we can’t remove this “feature” completely, we hope the enhancements will make a big difference.

The latest version (V1.4) of the Remote Connectivity Analyzer has the following improvements:

We are using a new CAPTCHA service provided by an internal team!!! EHLO rocks again!!!

  • The challenge is NOT case sensitive, so it doesn’t matter if you type upper or lower case letters. We also note this on the web page.
  • The CAPTCHA challenges will not include hard to distinguish letters/numbers. For example 2 and Z or O and 0.
  • If you get the challenge wrong, the password entries will not be removed.
  • Once you enter a correct response to the challenge, you will be verified for a set amount of time. This means you will not see additional CAPTCHA challenges until the timeout period expires.
  • The inbound SMTP test now inserts the IP address of the user performing the test into the test email message. The IP is also inserted into an SMTP Header (X-Originating-IP).
  • Fixed an issue in the Sender-ID test where certain DNS responses while evaluating the “exists” mechanism were incorrectly being treated as a TempError
  • The outbound SMTP Sender-ID tests now conform to the RFC specified limit of ten DNS-based mechanisms that can be used during the evaluation of the SPF record.

Exchange2010 – OAB/Outlook clients not downloading updated OAB


  • Outlook on Cache mode not updating..Disabling Cached mode on client manually fixes the problem.
  • OWA is not affected at all. All changes are instantly reflected in OWA.
  • Deleteing the .oab files in the user app data folder fixes the problem

This is not  a solution to this issue.

Create new OAB and perform the following tasks:

  1. Create new OAB from EMC.
  2. Make sure Web based and Public Folder distribution is enabled.
  3. Restart MS Exchange System Attendant and File Distribution Service.
  4. Update the OAB from EMC and Set it As Default.
  5. Associate the new OAB to Mailbox Database.
  6. Check the location for the .LZX files C:\Program Files\Microsoft\Exchange Server\V14\ExchangeOAB
    and C:\program files\Microsoft\Exchange Server\V14\ClientAccess\OAB\
  7. Make sure you don’t have web.config file @ .LZX file location.
  8. I hope you are doing full download of the OAB in Outlook.
  9. When you download the OAB, Make sure you uncheck the box“Download changes since last send/recieve”
  10. “Global Address Book” is the only option
After you restart the File Distribution Service on the CAS server, you should be getting the same files from the OAB generating server to the C:\program files\Microsoft\Exchange Server\V14\ClientAccess\OAB\ on the CAS server . You might want to set the logging level to high to see if any errors are generated on the OAB generating server.
  • Set-EventLogLevel –Identity LABMBX\MSExchangeSA\* -Level High 
  • Set-EventLogLevel –Identity “LABCASHT\MSExchangeFDS\*” -Level High
 the first one will get the OAB events and the 2nd will get the File Distribution Service events. Dont forget to set the logging back to defaults. After setting the logging, regenerate the OAB and then restart the FDS, check for errors in the corresponding event logs.
Wait for 24hours to get the replication

Attachments not showing in Microsoft Outlook

Interesting topic

ISSUE: When an user sends email with  attachment Microsoft Outlook clients don’t see paperclip nor attachment but the size of the mail shows there is more then just text. The attachment is visible in OWA. When forwarding the message from OWA the attachment shows up in outlook.

FINDINGS: I think the issue related to misformed MIME. The content type of the email is not correct; it is multipart/related, and should be multipart/mixed.

  • It may or may not be an issue on your end, incorrectly formatted mime messages sent by the sender can cause it not to render correctly in Outlook.
  • Things like the sender running third party apps such as disclaimers can mess up the mime formatting.
  • RFC 2387 describes the intended use of multipart/related:
    • “The Multipart/Related media type is intended for compound objects consisting of several inter-related body parts. For a Multipart/Related object, proper display cannot be achieved by individually displaying the constituent body parts.”
    • Exchange handles multipart/related specially – i.e. it considers all attachment parts inside multipart/related as “inline”. Such attachments are normally hidden from the attachment list and supposed to be accessible from the body itself, like inline images. Some clients, like OWA, can determine whether attachments are really “inline” by analyzing a message body – if they don’t find any reference to such attachment in a body they fix it by displaying it in attachment list. Other clients like Outlook will trust how attachments are marked by Exchange and hide them.
  • A “correct” way to structure message would look like this:
    • Multipart/mixed
    • Multipart/related
    • Text/html – message body
    • Any inline attachments referenced from the body
    • Any normal attachments, like application/msword

 SUGGESTION: Add a Transport Rule to simply “force” us to use multipart/mixed (Only when the mail is coming from the specific domain) and that will make the attachment visible in Outlook.

SOLUTION: Launch Exchange Management Console

  • Expand Organization Configuration
  • Select Hub Transport
  • On the right-hand Action Pane, select New Transport Rule …
  • Give the rule a name
  • Select when the From Address contains Specific Word click the highlighted “Specific words”, Type “”
  • click Add, click OK, and then click Next
  • Select “set header with value,” click the highlighted “header” text, type
  • Content-Type, click OK
  • Click the highlighted “value” text, type multipart/mixed, click OK, and then click
  • Next
  • On the “Exceptions” page, simply click next
  • At the final “Create Rule” page
  • Click New, and then click Finish
