About me

Hi, I'm Omer Eltayeb.

I'm an Intune Subject Matter Expert based in Cairo, Egypt, and a former Microsoft Cloud Solutions Architect. Since 2018 I've worked in security operations, consulting and cloud architecture across the Middle East and EMEA — and every one of those roles kept leading me back to the same place: the endpoint, and the identity, security and mail services around it.

Today I work as an Intune Subject Matter Expert with organisations that run Microsoft Intune — designing rollouts, training IT teams and getting them past the problems that stop devices — and the people using them — from getting work done: Windows Autopilot deployments that stall at the Enrollment Status Page, Win32 apps that install but never report success, compliance policies that lock the wrong people out, and Conditional Access rules that block the wrong sign-ins. Every one of those problems has a root cause, and finding it quickly is the part of the job I enjoy most.

Before that I spent two years at Microsoft as a Cloud Solutions Architect for enterprise customers across EMEA, where I was the industry lead for telecommunications, designed Intune and Configuration Manager co-management rollouts, moved organisations off legacy MDM platforms, delivered Active Directory and Exchange projects, and ran workshops for customer IT teams. Earlier roles — Principal Security Consultant at Dell Technologies, cloud and security consultant at NourNet, and information security specialist in a SOC — gave me the identity, Exchange, Defender and SIEM background that Intune troubleshooting draws on every day.

I hold a Master of Science in Cybersecurity and a Bachelor of Science in ICT, both from the University of Science & Technology, along with 28 professional certifications including CISSP, CCSP, CISM, CISA and PMP — all of them, together with my Microsoft programme badges, verifiable on my Credly profile. As a Microsoft Certified Trainer and Microsoft Innovative Educator Expert I deliver Intune, Azure and Microsoft 365 training to customer teams and to IT communities in Qatar and Sudan. This blog is the written version of that work: what you'll see, why it happens, how to fix it, and how to prove the fix worked.
