Increasing the maximum size of the Exchange 2003 Information Store

I’ve had to do this a lot recently, so I thought I’d make a permanent place-holder for the information on how to manipulate the server registry to allow Exchange 2003 to work with an Information Store larger than 14GB.  Exchange 2003 SP2 added the ability to configure database size limits.

To modify the size limits for either the mailbox/private store or the public store…

  • On the computer that is running Exchange 2003 SP2, click Start, click Run, type regedit, and then click OK.
  • Click one of the following registry subkeys, as appropriate for the store that you want to increase:
    • For a mailbox store, click the following registry subkey:

      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID

    • For a public folder store, click the following registry subkey:

      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Public-Public Store GUID

  • On the Edit menu, point to New, and then click DWORD Value.
  • In the New Value #1 box, type Database Size Limit in Gb, and then press ENTER.
  • Right-click Database Size Limit in Gb, and then click Modify.
  • Click Decimal, and then type an integer from 1 to 75 in the Value data box.
    Note These integer values represent the maximum size of the database in gigabytes (GB). For example, a value of 75 represents a database that has a maximum size of 75 GB.
  • Click OK, and then exit Registry Editor.
  • Restart the Microsoft Exchange Information Store service. To do this, follow these steps:
    1. Click Start, click Run, type cmd, and then click OK.
    2. At the command prompt, type the following command, and then press ENTER:

      net stop msexchangeis

    3. After the Microsoft Exchange Information Store service has stopped successfully, type the following command, and then press ENTER:

      net start msexchangeis

  • Examine the Application log to verify that the database size has been set successfully. To do this, follow these steps:
    1. Click Start, click Run, type eventvwr, and then click OK.
    2. In the Event Viewer tool, click Application.
    3. Double-click event ID 1216 to verify that the database size has been set successfully.
  • Txt Gateways for Sending Txt Messages from an Email Client

    You can send a txt message to anyone who can receive txt messages on their phone or smartphone using your favorite email client – you just need to know the remote phone number along with the provider gateway information.

    Here’s a few:

    Microsoft Exchange Server Remote Connectivity Analyzer

    Ever have Exchange remote connectivity problems that you just couldn’t diagnose – particularly for Windows Mobile devices?

    I’m not sure how long this site has been up, but Microsoft has a beta site that allows you to enter remote information for your Exchange implementation, and it will try to connect and diagnose the situation.  This really saved me some time today, after I just happened onto it.

    Check it out:

    Microsoft Exchange Server Remote Connectivity Analyzer

    If it finds problems with your remote connectivity, it will show you the steps in the process and flag the step that failed.  Then, it will give you a link to a page that tells you how to fix the issue.

    Why organizations need an email archiving system

    MAR_Logo Emails are a standard and vital means of communication in today’s organizations, used to communicate internally between colleagues and management, as well as for external contact with suppliers and clients. This medium is heavily relied upon for work to continue smoothly on a day-to-day basis; however, this reliance on emails has led to end users taking the service for granted and ignoring the storage problems that the sheer amounts of emails generate on a daily basis.

    Email archiving is one of the first steps to a successful email management program. It has become a standard procedure in most organizations, especially due to recent compliance regulations and legislation which have made email archiving obligatory. Emails are considered to be legal documents in a court of law and organizations need to be able to provide any requested emails and prove that these have not been tampered with in case of legal proceedings; failure to do so by organizations can lead to hefty fines that could cripple a business.

    Maintaining an archive of all the company’s email correspondence, makes them easily searchable and recoverable, and therefore reduces the dependence on PST files that can easily get corrupted and cannot guarantee secure backups of email data. A good email archiving software also eliminates the responsibility from workers having to decide which emails are important and worth keeping, and simply keeps a log of all email correspondence. Therefore even if an employee deletes emails from their user account the archiving server would still have a copy of it stored. This could also come in useful for the human resources department who may have to deal with dismissal or harassment cases where there could be important evidence on email.

    Large volumes of email correspondence, increased storage limitations, government regulations and potential legal implications have made the need for email archiving a critical issue for any company.

    GFI MailArchiver for Exchange provides easy-to-use corporate email archiving for SMBs, providing administrators with the tools to let their users archive and recover past emails through Outlook or through a web interface. GFI MailArchiver also helps meet the requirements of email retention policies (such as Sarbanes-Oxley) and helps fulfill regulatory email storage requirements.

    Interesting Out of Office message…

    “Unfortunately I might be unable to respond to most emails during working hours but will see to it after hours, if it is urgent please SMS me on my mobile.”

    Incidentally, this was sent to a work email address.  Makes you wonder what that work email address is being used for.

    Google News Alerts gone crazy

    I receive Google News Alerts in email to keep track of certain topics around the web.  These usually work great, except today, I think Google is having trouble figuring out what language to send me.

    Here’s a recent one for InstallShield with German and French entries:


    And, here’s one for the System Center Management Suite topic in Chinese, Italian, French, and one listing from Hungary:


    One has to wonder if Google is having issues lately that they simply aren’t talking about or reporting.  If you remember, they have been having Gmail issues, lately.
