Outlook Integration in Portsmouth
Integrating Outlook and Exchange for Portsmouth organisations, where the permission type decides the blast radius. Delegated permissions act as a signed-in user and reach only their mailbox; application permissions reach every mailbox in the tenant — and the second is frequently granted because it was simpler to configure than to scope.
Why this comes up
The problem
The integration holds application-level mail permissions, so it can read every mailbox in the organisation.
What you get
What we deliver
- Delegated or application permissions chosen against the actual requirement
- Application access scoped to specific mailboxes where that route is necessary
- Consent documented, since tenant-wide grants are a governance decision
- Change notifications used rather than polling mailboxes for new messages
- Recurring meetings handled as series with exceptions, not individual events
- Throttling handled, as sustained mailbox access is rate limited

Outlook Integration in Portsmouth — common questions
- What is the difference in practice?
- How much the integration can see. Delegated access is bounded by the user it acts for; application access covers the tenant unless deliberately restricted — so an integration needing one shared mailbox should not be granted the ability to read all of them.
- Can application access be limited?
- Yes, to specified mailboxes through an access policy. It requires configuration rather than being the default, and it is what makes application permissions proportionate — a shared inbox integration reaching only that inbox rather than everyone's.
- Why does consent need documenting?
- Because a tenant-wide grant is an organisational decision with real implications. Recording what was granted, to which application and why gives whoever reviews access later something to assess — rather than an approved permission nobody can account for.
- Should we poll for new mail?
- No — use change notifications. Polling mailboxes is slow, hits throttling and delays the response, whereas a subscription notifies you when something arrives, which is both lighter and what makes mail-triggered workflows feel immediate. Subscriptions expire and need renewing, so that renewal has to be part of the design rather than something noticed when notifications quietly stop.
- 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.
