Microsoft 365 Migration in Portsmouth
Moving Portsmouth organisations' mail and files into Microsoft 365 without losing anything or stopping work. The two things that consistently go wrong are shared mailboxes and calendars — permissions and delegate access rarely survive a migration untouched — and file shares where nobody knows what half the folders are for.
Why this comes up
The problem
Mail sits on an ageing server or another provider, files are on a share nobody has audited in years, and the business cannot afford a day without email.
What you get
What we deliver
- An inventory of what actually exists, including the mailboxes nobody remembers
- Shared mailboxes, delegates and calendar permissions mapped before the move
- Mail migrated in stages with a cutover that avoids a gap in delivery
- File shares reviewed, with obsolete material archived rather than migrated
- Permissions rebuilt deliberately instead of copied from an unclear original
- Mobile devices and mail clients reconfigured, which is where user disruption lands

Microsoft 365 Migration in Portsmouth — common questions
- Will we lose email during the move?
- Not with a staged cutover. Mail is copied ahead of time and the final switch is a short window with delivery queued rather than rejected. Migrations that lose mail are usually ones where the change was made before the copy completed.
- Why are shared mailboxes a problem?
- Because their permissions are invisible until they break. Delegate access, send-as rights and calendar sharing exist in configurations nobody documented, and after migration people quietly lose access to things they have used daily for years. Mapping them beforehand prevents a difficult first week.
- Should we migrate everything?
- No. File shares typically hold years of duplicated and obsolete material, and moving it wholesale imports the mess and the cost. Archiving what is genuinely dormant, and migrating what is in use, makes the destination usable rather than merely a copy.
- What causes the most user disruption?
- Devices. Phones with the old mail account, desktop clients holding cached profiles and printers scanning to an old address all need attention, and these are the things people notice immediately. Planning for them turns a difficult morning into an uneventful one.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
