I work in an after-sales department for a machinery company. Our four-person team is split between spare parts and service, and we receive roughly 40 spare-parts emails and 30 service emails each day through shared Outlook mailboxes.
Everyone normally handles their own customers, but coverage becomes difficult when someone is absent. Messages are missed, ownership is unclear, and it is hard to tell which requests are waiting for a response. We also have no reliable way to measure response times, backlog, or workload by person.
We are considering a ticketing system or a shared-inbox tool that integrates with Outlook. Ideally, it would assign an owner, track status, prevent messages from being forgotten, support handoffs, and provide reporting.
Has anyone moved from shared mailboxes to a ticketing or CRM system? Which tools worked well, and what process changes were important during the transition?

At that volume, a proper helpdesk or CRM with ticket functionality is worth considering. Emails can flow into queues for spare parts and service, with each request assigned to an owner and given a status. Look for internal notes, collision prevention, reassignment during absences, SLA or response-time tracking, backlog views, and reporting by queue and person. Freshdesk, Zendesk, Help Scout, Front, Jira Service Management, and Dynamics are all reasonable tools to compare. The important rule is simple: if a request has no owner, it is not considered handled.
You may not need a full CRM right away. Shared-inbox products such as Missive or Front can add assignments, snoozing, internal comments, shared conversation history, and workload metrics without turning every message into a heavyweight ticket. This can be a good middle ground if your team mainly needs better email coordination rather than a large service-management platform.
A useful approach is to measure the current situation before migrating. Gather the number of incoming messages, first-response times, unanswered items, repeat follow-ups, and workload per person. That will show whether the main problem is routing, follow-up, staffing, or uneven workload, and it will help you choose between a shared-inbox tool and a full helpdesk. Start with a small pilot, document the workflow, and expand only after the team is using it consistently.
If you must stay with Outlook for now, create a clear interim workflow. Use separate queues or folders for spare parts and service, assign messages to individual folders or categories, and have explicit statuses such as New, In Progress, Waiting for Customer, Waiting for Supplier, and Completed. Set a rule that nothing remains in the general inbox overnight and use reminders for anything awaiting a reply. This can improve control quickly, although it will not provide the same quality of reporting as a ticketing system.
Before buying anything, define the process. Decide who triages new messages, how ownership is shown, which statuses are allowed, when something is considered complete, and who checks the queue each day. Also agree on how supplier follow-ups, attachments, spam, and urgent requests are handled. A new tool will not fix the problem if people continue working around it or create an informal hybrid system.

Planner in Teams can also work as a lightweight starting point if you already have Microsoft 365 licenses. It gives you assigned tasks, due dates, and a shared board, though you may still need another method for keeping the original email conversation and response metrics together.
