À propos de moi
Six years supporting Microsoft's enterprise customers on Exchange Online - including CritSit, Microsoft's highest priority support tier, where failed migrations land after everyone else has tried. 15 years in IT overall.
Most of my work is email migration to Microsoft 365: Exchange Hybrid, IMAP, and Google Workspace, planned so your users keep working while the mailboxes move.
I also handle mail flow and routing, SPF/DKIM/DMARC and deliverability, Entra ID, Teams, OneDrive, and PowerShell automation.
Tell me what you need, and let's start with a free 15-minute consultation.
