As a global business dealing with clients across various time zones, email communication is not just essential but needs to be 24/7 without any disruptions. In the Spring of 2010, their corporate email system, powered by [Microsoft Outlook](https://www.microsoft.com/en-us/microsoft-365/outlook/email-and-calendar-software-microsoft-outlook), started experiencing frequent crashes and errors. [PST files](https://support.microsoft.com/en-au/office/introduction-to-outlook-data-files-pst-and-ost-222eaf92-a995-45d9-bde2-f331f60e2790) got corrupted, important emails were lost, and the overall productivity of the team was affected significantly. Every day, hundreds of thousands of emails were sent and received, and the occasional file corruption caused havoc in the regular workflow. The internal IT department was unable to solve the problem efficiently, and the inefficiency in email communication was starting to impact customer relations and satisfaction. ## **The Solution** Realizing the gravity of the situation, the IT department of [Deloitte](https://support.microsoft.com/en-au/office/introduction-to-outlook-data-files-pst-and-ost-222eaf92-a995-45d9-bde2-f331f60e2790) began looking for a robust and effective tool to fix their recurring issues.
