Exchange Admin Center language

Depending on your computer language settings, Exchange Admin Center can take those and open in a language you actually don't want to use.
You'll Google that this can be changed if administrator/ admin user has mailbox by openening OWA settings and changing Regional parameters.

But usually Admin user does not have mailbox or you don't want her/him to have it. You will search again and find that you can add mkt=en-US (as an example) to the URL of the Exchange Admin Center (https://yourexchangehostname/ecp?ExchClientVer=15&mkt=en-US)

Third option you have is opening Internet Explorer settings (I am using Windows 2016)

Click languagesClick Set Language Preferences

Add language you want to use by clicking Add language
Use Move up or Move Down options to put desired language on topClose Internet ExplorerOpen it again and login again to Exchange Admin Center

How to remove Active Directory Connectors before installing Exchange 2007

"Microsoft® Exchange Server 2007 setup cannot continue because one or more Active Directory Connectors have been found..."

This is the error you get when Exchange 2007 setup tries to run /PrepareLegacyExchangePermissions command and founds out that you have one or more Active Directory Connectors (ADC) installed in your organization. You should remove all Active Directory Connectors from organization prior to installing Exchange 2007. I suggest that you first run Exchange Best Practices Analyzer with Exchange 2007 Prerequisites Check before you start with Exchange 2007 installation.

To remove Active Directory Connector components

  1. To disable the ADC service on the server that is running the ADC service, right-click My Computer on the desktop, and then click Manage
  2. Expand the Services and Applications node, and then click the Services node.
  3. In the right pane, right-click Microsoft Active Directory Connector and then click Properties.
  4. Change the Startup Type to Disabled. The next time that the computer starts, the ADC service will not start.
  5. Click Apply, and then click OK.
  6. To uninstall the ADC service, use the Active Directory Installation Wizard on the Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 CD. Open the \ADC\I386 folder and double-click the Setup.exe program. Follow the prompts to Remove All ADC service components.

You must complete step 6 and Remove All ADC components to resolve this issue. It is insufficient to disable the ADC service.

If you somehow removed the server with ADC installed from your organization without completing this steps than there is always possibility that the object still resides in Active Directory. To remove it manually follow the procedure which assumes your Exchange server was not Domain Controller:

Suggestion: Create backup of System State on at least two DC's before this procedure

  1. open Active Directory Sites And Services
  2. Check if there is an object of removed server under the Site where this server resided
  3. Delete this object with all sub-objects
  4. Replicate changes to all other DC's

Using ADSIEdit:

  1. Install Support Tools from Windows 2003 CD
  2. Open Microsoft Management Console (mmc)
  3. Add ADSIEdit snap-in
  4. Connect to Configuration Container
  5. Expand Configuration --> Services --> Microsoft Exchange --> Active Directory Connections
  6. Delete ADC under Active Directory Connections
  7. Replicate changes to all Domain Controllers

After you complete these steps, rerun the Exchange 2007 setup or /PrepareLegacyExchangePermissions command, depends on whatever you run first.


  1. I received this error, but have no connector under Services?
    How is this possible?

  2. If you have many DCs in your environment, check all of them. Maybe one of them is holding the data while the replication does not work and therefore this DC is not updated.

  3. I followed all instructions and everything went well until step 6. When you run the setup.exe you get an error telling you that the version of the installer is older than the one you last used. I presume that this is because the Exchange server is running with SP3? How do I get the ADC to uninstall?


  4. You're a star man! Almost 2 yrs after your article, your tips helped manually remove ADC and SRS, and change Exchange mode to Native. Keep it up, thanks for your valuable tips!

  5. Is it possible to remove the ADC connector software using the add/remove program??

  6. As written above, you need to use Exchange installation disk or use the manual removal procedure.

  7. I am finding more than one ADC in ADSIedit. Do I remove them all? i.e. Default ADC Policy.

  8. @Eric - You must delete all the connectors there are, otherwise you will not be able to proceed.

  9. Thanks a lot, Manual removal works like a charm :)

Error "<#5.5.2 smtp;554 5.5.2 Invalid data in message> #SMTP#" when you send attachment in your mail

Some users were receiving error <#5.5.2 smtp;554 5.5.2 Invalid data in message> #SMTP# when they sent message with attachment. The problem is when attached document name is longer than 50 characters. Some Firewalls have header size restriction and that limit blocks this messages to be sent. To correct this, change header limit on affected Firewall or shorten the name of the document you are sending (which is probably not good permanent solution).******
Update #1: Default header size limit in Exchange 2007 is 64K.Update #2: It might be the SMTP version problem. Mail is rejected with CONTENT-DISPOSITION error (overly long message header field for CONTENT-DISPOSITION) but not for all SMTP servers (same mail sent through different SMTP servers). If you send mail with attachment that has name longer than 50 characters from Exchange 2007 directly through DNS you may encounter this error, but if you send same mail from Exchange 2007 through smart host (other than Exchange) mail is d…

Change SMTP port 25 in Exchange 2007, 2010

For some reason you might want to change default SMTP port number 25 Exchange 2007 is using. Exchange 2007 uses RECEIVE AND SEND connectors, one for receiving mails and other for sending mails (obviously ;)
So you need to change ports on those connectors. I will not say those two, because you might be using more than two.
You change Receive connector port by opening the connector properties in Exchange Management Console --> Hub Transport --> RECEIVECONNECTORNAME --> Properties --> Network --> Local IP Addresses (Edit Receive Connector Binding)
Just to clarify what "Local IP Addresses" and "Remote Servers" are (from Exchange 2007 help), because I find it little bit confusing: Use these local IP Addresses to receive mail Use this list to specify the IP addresses and port numbers on which this Receive connector listens for incoming mail. Receive mail from remote servers which have these IP addresses Use this list to specify the remote IP address range fr…
