SYMPTOMS
The following event may be logged in the Application event log on a computer that is running Small Business Server (SBS) 2000:

Source: LicenseService

Event ID: 201

Description:

No license was available for user domain\user using product MSExchangeIS.

Additionally, the following event may be logged in the System event log:

Source: Application Popup

Event ID: 26

Description:

Application popup: License Warning: License usage for a product licensed in per server mode has exceeded the maximum number of licenses purchased and will prohibit further licenses from being granted. Consult the Application event log, or License Manager from the Administrative Tools folder for more information.

You may also receive the following error message on client computers that try to start Microsoft Outlook:

There are no additional Microsoft Exchange licenses available.

Contact your system administrator to obtain a client license to use Microsoft Exchange.

If you start Exchange System Manager, you may see several connections from the same account in the Logons section under the Servers,  , First Storage Group, and Mailbox Store items. Typically, this account is the account that is configured to be used by your backup software.



CAUSE
This issue may occur if Veritas Backup Exec version 8.6, revision 3808 or 3878, is configured to perform backups on the server by using the Mailbox option. Backup Exec does not properly close the connections that it opens to the Microsoft Exchange server. This eventually consumes all of the available client access licenses.

This issue does not occur with the Information Store backup option in Backup Exec.



WORKAROUND
You can resolve the licensing errors by following the instructions that are listed in the following Microsoft Knowledge Base article:

305138 &quot;Out of License&quot; Error Messages in SBS 2000 Event Logs

Although the license errors will stop appearing, Backup Exec still creates the connections without properly closing them. To work around this behavior, use any of the following methods:
 * Stop and restart the Backup Exec Job engine to release the used licenses.
 * Use the Information Store backup option in Backup Exec instead of the Mailbox option.



MORE INFORMATION
The Veritas support Web site reports in TechNote ID: 241675 that &quot;Backup Exec 8.6 Small Business Server does not release connections / sessions to the Exchange Server, and subsequent client connections are not permitted due to the Client Access Licenses (CAL) being depleted.&quot;
