At Infosys LIMITED, I administer Microsoft 365 services for an enterprise environment supporting 60,000+ users. My work spans Exchange Online, Microsoft Entra ID, Intune, Microsoft Defender, Teams, SharePoint Online and OneDrive.
I strengthened SPF, DKIM and DMARC email authentication controls, reducing phishing incidents by nearly 40%. I also achieved 100% device compliance through Intune policies and compliance-based Conditional Access, while handling 80–120 tickets per month in L2 operations.
