Microsoft 365 Integration in Brighton

Connecting a Brighton organisation's own software to Microsoft 365 — mail, calendars, files, Teams. Almost all of it runs through Microsoft Graph, and the decision that matters most is permissions: application permissions grant access to every mailbox in the tenant, which is rarely what anyone intends.

Why this comes up

The problem

Your application needs to read calendars, send from company addresses or store documents in SharePoint, and the permission model is unfamiliar territory.

What you get

What we deliver

  • Graph permissions scoped to the minimum, with delegated preferred over application
  • App registration configured properly in Entra ID, with consent understood
  • Calendar, mail or file access implemented against the correct Graph endpoints
  • Change notifications subscribed to rather than polling, with renewal handled
  • Throttling handled, since Graph will rate-limit and expects backoff
  • Documentation of what the app can reach, which auditors will ask for

Microsoft 365 Integration in Brighton — common questions

What is the difference between delegated and application permissions?
Delegated acts as the signed-in user and sees only what they can see. Application permissions act as the app itself and typically reach the whole tenant — every mailbox, every file. Use delegated wherever the work happens on a user's behalf.
Can we restrict application permissions to certain mailboxes?
Yes, and you generally should. Application access policies limit an app to a specified group rather than the whole organisation. Without one, an integration for a single team can read the chief executive's mail, which is difficult to defend in review.
How should we detect changes?
Graph change notifications rather than polling — faster and far less load. Subscriptions expire and must be renewed on schedule, and a renewal that fails silently is the common cause of an integration that quietly stops noticing anything.
Why do requests start failing under load?
Graph throttles, returning 429 with a retry-after header. It is expected behaviour rather than a fault, and integrations that ignore backoff make it worse by retrying immediately into the limit they just hit.
Do you work with businesses across East Sussex?
Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Brighton and the surrounding East Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Brighton businesses do you usually work with?
Design-led briefs from a market that judges craft closely, plus hospitality and visitor systems for the local economy. Beyond that we work across Digital & Creative, Tourism & Hospitality, Higher Education and Retail.
Do you cover the areas around Brighton?
Yes — we work throughout South East, including London, Southampton. Brighton is an urban area of roughly 290,000+, and we take on work across the wider East Sussex region rather than the city boundary alone.
