You keep Microsoft 365 and email running through an outage with resilient connectivity, good Microsoft 365 configuration, email continuity where it matters, and fast support to deal with problems. Email is often the most critical day-to-day system a firm has, so a bit of planning to keep it flowing, even when something goes wrong, is well worth it.

Outages happen, whether a local internet fault or a wider issue. Here’s how to keep communication going.

1. Resilient connectivity

Much of what feels like an email outage is really a lost internet connection. Resilient connectivity, with a backup line where it matters, keeps your team reaching Microsoft 365 even when one line fails.

2. Work from anywhere

Because Microsoft 365 is cloud-based, a problem at one office does not have to stop people working. Staff can keep using email and files from home or another location, which is a natural form of resilience.

3. Email continuity where needed

For firms that cannot be without email, continuity services can keep mail flowing even during a wider outage. We help you decide whether this is worth it for your business and set it up if so.

4. Fast support and good configuration

A well-configured Microsoft 365 environment has fewer problems, and when something does go wrong, fast support gets it resolved. Together these keep email reliable day to day.

A real example: email kept reliable

We supported a software company serving financial trading firms where we managed their Microsoft 365 and email across global offices, with resilient connectivity and quick support, so communication stayed reliable. When an email issue did arise, the response was fast and the user noted the “good communication and follow up.”

For a software, technology or financial trading firm, this is part of managed IT and security that usually costs about £45 to £100 per user per month, scaling with your headcount, your security needs and how much uptime the business depends on.
