You manage your company's email system and you know that a missing email means a lost client or a missed contract. You need a partner who plans every step, tests before switching, and guarantees that Monday morning everything works. You want concrete results, not promises.
You have hundreds of mailboxes to migrate, regulatory constraints on data retention, and a leadership team expecting zero disruption. You need a certified service provider who handles complex migrations and documents every step.
Your current email system (OVH, 1&1, Gandi, local host) is showing its limits: insufficient storage, no integrated collaboration, basic security. You want to move to Exchange Online to benefit from a modern, secure, and Microsoft 365-integrated professional email solution.
We configure your Microsoft 365 tenant: creating each user, assigning the appropriate Exchange Online licenses, setting up shared mailboxes and distribution lists. Your environment is ready before the migration begins.
We migrate all your mailboxes: emails, contacts, calendars, tasks. Whether you are coming from Exchange on-premises, Gmail, Lotus Notes, OVH or any other provider, every item is transferred and verified. Zero data loss is our commitment.
We configure your DNS records to point to Exchange Online: DKIM (email signing), DMARC (authentication policy), SPF (sender verification), AutoDiscover (automatic email client configuration). Your emails are delivered correctly and protected against spoofing.
Once the migration is complete, we verify each mailbox: full synchronization, intact folders, active sorting rules, updated signatures. We configure Outlook clients on every workstation and mobile device. Nothing is left to chance.
Your users are trained on Outlook: email management, shared calendar, contacts, advanced search. Hands-on sessions in small groups, tailored to each team's skill level. We train for autonomy, not dependency.
We activate multi-factor authentication (MFA) on each account to protect your access. Dedicated technical support remains available after the migration to answer your questions and resolve any issues. Response within 4 hours.
We analyse your current email system in 30 minutes: number of mailboxes, data volume, current provider, technical constraints. We identify risk areas and give you a timeline estimate. No commitment required.
You receive a complete plan: inventory of mailboxes to migrate, migration schedule (in batches or all at once), planned DNS configuration, test checklist. The schedule is adapted to your constraints — weekend migration, by department, during off-peak hours.
We set up the environment, launch the data migration, and switch the DNS. Your teams continue to receive and send emails throughout the entire process. Critical steps are scheduled during off-peak hours to minimise any residual risk.
We verify each mailbox point by point. We train your teams on Outlook. We activate MFA. And we remain available for post-migration support. Your email system is operational, secure, and mastered by your teams.
Professional cloud email: 50 GB per mailbox, shared calendars, centralised contacts, web/mobile/desktop access. The reference email platform for businesses.
Exchange Online is part of Microsoft 365. The migration is an opportunity to also deploy Teams, OneDrive and SharePoint for complete collaboration.
The email client included in Microsoft 365. Familiar interface, powerful search, native integration with Teams and calendar. Available on Windows, Mac, web and mobile.
« We had 180 mailboxes at OVH and the migration worried us. Air Cloud planned everything over 2 weeks, migrated the bulk over the weekend, and Monday morning everyone had their emails, contacts, and calendars. Not a single lost email. And the Outlook training accelerated adoption. »
