Acquisition of Privately Held Wingra Technologies Adds Two New Products to
Quest Migration Suite for Exchange

IRVINE, Calif., February 23, 2005 – Quest Software, Inc. (Nasdaq: QSFT), a leading provider of application, database and Windows management solutions, has expanded its portfolio of migration software products with the recent acquisition of Wingra Technologies, a privately held company based in Madison, Wisconsin. The people and products of Wingra are now part of the Windows Management group at Quest, bringing more than a decade of experience in migration across diverse messaging environments.

The newly acquired products include:

· GroupWise Migrator for Exchange – converts and moves user mailboxes and files from Novell GroupWise to Microsoft Exchange 2003 environments.

· Notes Migrator for Exchange – converts and moves mailboxes and files from Lotus Notes to Microsoft Exchange 2003.

“Like Quest’s other migration products, these new additions tackle technically difficult tasks in ways that make migration faster, easier and more secure for IT while minimizing migration-related business disruption,” commented Steve Dickson, general manager, Quest Windows Management group. “These talented individuals and top quality products are valuable additions to Quest.”

“The acquisition by Quest Software, Inc. is the perfect culmination of Wingra’s strategic plan,” stated Jan Eddy, President and CEO, Wingra Technologies, LLC. “Quest’s worldwide sales and marketing capabilities significantly increase the opportunity for our products to reach market penetration levels Wingra would not otherwise have achieved. Growth of this kind is very good for all Wingra stakeholders. The presence of a Quest office here in Madison adds additional credibility to our area’s already vibrant high technology community.”
