I need all 20–25 of my Microsoft 365 mailboxes moved to Google Workspace with zero data loss and minimal disruption to my team. Each account must arrive intact—emails, folder structure, calendars, and contacts—while retaining the exact same email addresses on the new platform. Two users are especially large (about 20 GB and 40 GB), so I want their mailboxes migrated first to make sure they are fully operational before we switch the rest. I prefer you work with Google’s native Migration Tool; that should cover authentication, throttling, and delta passes, but feel free to suggest small add-ons or scripts if they speed verification or cut downtime. All traffic must remain secure in transit, and I expect you to configure any required OAuth scopes, DNS changes, and coexistence settings so that mail keeps flowing during the cut-over window. Once the data is across, you will: • validate every mailbox for completeness, confirming message counts, labels/folders, calendar items, and contacts against the source; • switch MX records when I give the go-ahead and test inbound/outbound flow; • provide a concise hand-off report that lists what was moved, any errors you resolved, and confirmation that both large accounts finished first. After go-live, I’ll need a brief period of post-migration support—answering user questions, re-mapping mobile devices, and addressing any lingering sync issues. If you have recent, verifiable experience performing Microsoft 365-to-Google Workspace moves of a similar size, I’m ready to start as soon as we agree on a schedule that keeps downtime to an absolute minimum. NDA will be shared by me, will prioritise your legitimacy

Migrating a company’s entire email environment is not just a technical task; it’s a business-critical operation where one mistake can mean lost emails, broken calendars, frustrated employees, and hours of downtime. Many teams struggle because migrations are rushed without proper planning, verification, and a safe rollback approach. Hi, I'm Victor, a Microsoft 365 and Google Workspace support specialist with 4+ years of experience handling cloud setup, account management, data organization, and technical workflow improvements for businesses. A recent client shared, "Victor handled our technical transition smoothly. His attention to detail, communication, and ability to solve issues quickly made the entire process stress-free." For your migration, I’ll approach it carefully—starting with the two largest mailboxes, configuring secure authentication, handling DNS/MX changes, migrating emails, calendars, and contacts, then validating each account before full cutover. I’ll also provide clear documentation and post-migration support to ensure your team adapts without disruption. I understand the importance of trust during a migration like this, and I’m comfortable working under NDA while keeping every step transparent. Could you share your current Microsoft 365 setup (tenant type, mailbox size distribution, and preferred migration date) so I can map the safest migration timeline for your team?
