Microsoft 365 migrations, administration, and email that behaves.
Evolve moves businesses onto Microsoft 365, configures it the way it should have been set up the first time, and administers it afterward — licensing, users, mailboxes, MFA, and the security settings most tenants never had turned on.

A defined project, or somebody who administers the tenant.
Most businesses come to us with one of these. They are priced differently and they solve different problems, so it is worth being clear which one you are actually asking for.
One thing, scoped and finished
A migration from an old mail host or an on-premise Exchange server. A tenant cleanup. Getting MFA rolled out properly. Moving a file share into SharePoint. Quoted in writing, with a date and a defined finish line.
- Migration and cutover, including the weekend ones
- Tenant and licence cleanup
- MFA and identity rollout
- Documentation of the final configuration
No ongoing agreement required. Project and hourly work is handled through Business IT Support.
Someone who owns the tenant
Microsoft 365 is not a product you finish configuring. People join and leave, licences change, Microsoft changes defaults, and security settings need revisiting. Ongoing administration means those are somebody’s job rather than nobody’s.
- New hires and departures handled the same way every time
- Licences reviewed so you stop paying for people who left
- MFA and access kept current, not audited once
- Mail flow, filtering and quarantine looked after
Included in Managed IT plans from Foundation upward, or available on its own.
Nobody should notice a migration except the person who paid for it.
Moving mail is the part of this work most likely to go visibly wrong — bounced messages, a signature that vanished, a shared calendar nobody can see. Most of that comes from rushing the two steps before the cutover.
Find out what is actually there
Mailbox sizes, shared mailboxes, distribution lists, the calendar the whole office relies on, forwarding rules, and who controls the domain name. The last one delays more migrations than anything technical.
Build the tenant before touching mail
Licensing sized to what people need, accounts created, groups and shared mailboxes recreated, MFA and security settings configured, and mail authentication records prepared in advance.
Copy the mail across first
Mailboxes are synchronised while the old system is still live, so cutover night moves a small delta instead of years of email. This is the step that gets skipped when a migration is rushed.
Switch mail delivery out of hours
Scheduled for an evening or a weekend, with the order of operations written down beforehand and mail flow watched afterward rather than assumed.
Be there the first morning
Phones, signatures, the scan-to-email on the copier, the one application that sends mail from a hard-coded address. Small things, all of them on the first morning.
- An old mail host or registrar mailbox into Microsoft 365
- On-premise Exchange to Exchange Online
- Google Workspace to Microsoft 365
- A file server into SharePoint or OneDrive
- Two tenants merged after an acquisition
Have a date or a renewal you are working against? Tell us what you are on now and how many mailboxes, and we will tell you what the move involves.
Six things we commonly find in tenants we take over.
None of these mean anyone was careless. They are what happens when a tenant is set up once, in a hurry, and then changed by whoever was available. The first thing we do is write down what is actually in there.
Licences nobody cancelled
Real money, every month, for people who left and for plans nobody chose deliberately. Some businesses are paying for premium licences on accounts that only send mail.
Inventory every licence against a current staff list, right-size the plans to what people actually use, and cancel the rest at the next renewal date. The licensing savings can offset part of the cleanup cost.
Accounts belonging to people who left
Live credentials for people who no longer work there — sometimes still receiving mail, sometimes still signed in on a personal phone.
Archive the mailbox somewhere the business can still reach it, convert or remove the account, revoke sessions, and put an offboarding process in place so the next departure is handled the same way.
MFA on some accounts
Partial coverage reads as protection on an insurance form and is not. The accounts left out are usually the oldest and the most senior.
Roll MFA out across every account including administrators and contractors, disable the legacy sign-in methods that quietly bypass it, and give you the coverage list in writing. More in Cybersecurity.
Shared mailboxes with no owner
info@ and billing@ that six people can read and nobody is responsible for, plus mail rules set up years ago that still forward copies somewhere.
List every shared mailbox and group with who has access, assign an owner, remove access that is no longer appropriate, and document the forwarding rules that remain.
Mail authentication half-configured
Your own invoices landing in customers’ junk folders, and anyone on the internet able to send mail that looks like it came from your domain.
Set SPF, DKIM and DMARC correctly for every service that legitimately sends as you — the mail host, the newsletter tool, the accounting system — then tighten the policy once nothing legitimate is failing.
Nothing written down
No record of who has administrator rights, which settings were changed, or why the exception from last March was made. Every question becomes an investigation.
Document the tenant as it stands — administrators, licences, groups, shared mailboxes, security settings — and keep it current as things change. The documentation is yours to keep.
Your email is the front door to everything else.
Many of the security incidents we get called about start with a mailbox: a password reused somewhere else, an invoice that looked legitimate, a forwarding rule nobody noticed. These are the settings that matter, and most of them are included in licences businesses already own.
MFA everywhere, legacy sign-in closed
Multi-factor on every account, administrator access separated from daily logins, and the older sign-in methods that bypass MFA switched off. Coverage given to you as a list rather than an assurance.
Filtering, impersonation, quarantine
Anti-phishing and impersonation protection tuned so it catches the invoice-fraud email without burying legitimate mail, external-sender warnings turned on, and a quarantine somebody actually reviews.
SPF, DKIM and DMARC set properly
So your mail is trusted by the people you send it to, and so somebody else cannot send mail that appears to come from your domain. Every legitimate sending service accounted for first.
The defaults worth changing
Automatic external forwarding, anonymous sharing links, who can consent to third-party apps, and audit logging left on. Reviewed against how your business actually works rather than switched on blindly.
Configuring these reduces risk; it does not eliminate it, and we will not tell you otherwise. The wider security picture — endpoints, firewall, network — sits on Cybersecurity.
Microsoft keeps the service running. Your data is your responsibility.
This is the single most common misunderstanding we run into. Microsoft holds deleted items for a limited window and then they are gone — which is not the same as a backup you control. A mailbox removed when someone left, a SharePoint library overwritten, a folder emptied four months ago: past those windows, none of it comes back.
A separate Microsoft 365 backup with retention you choose covers mail, OneDrive, SharePoint and Teams, and means a request from last spring is a restore rather than an apology.
- Mailboxes, including ones belonging to people who left
- OneDrive contents for every user
- SharePoint sites and document libraries
- Teams files and channel conversations
- Retention you set, not a fixed vendor window
OneDrive, SharePoint and Teams, set up so people can find things.
Moving a file server into Microsoft 365 goes wrong when it is treated as a copy job. The structure and the permissions are the work; the upload is the easy part.
OneDrive for individual work
Desktop, Documents and the folders people keep on their machines, synchronised and recoverable — so a failed laptop is an inconvenience rather than a loss.
SharePoint for shared files
A structure that matches how the business is organised, permissions by team rather than by exception, and version history that survives someone overwriting a file.
Teams without the sprawl
Teams and channels created deliberately, with owners, rather than accumulating until nobody knows which one the current version of a document is in.
Sharing that is deliberate
External sharing set to what your business needs, so a link sent to a client does not quietly become a link anyone can open, and old external access gets reviewed.
The same steps every time, whoever is doing it.
Most of the mess in the tenant ledger above comes from these two moments being handled ad hoc. Written down, they take minutes; improvised, they leave licences running and mailboxes live for years.
- Account created to a standard, with the right licence for the role
- MFA enrolled on day one, not when there is time
- Group and file access by role, so nothing is missed or over-granted
- Mailbox, signature, Teams and OneDrive ready before they sit down
- Laptop set up and enrolled, with endpoint protection on it
- Sign-in blocked and active sessions revoked immediately
- Mailbox archived or converted so the business keeps the history
- OneDrive contents handed to their manager before anything is removed
- Licence released at the right time instead of billing on
- Access to shared mailboxes and external systems removed and recorded
If you would rather not run these yourself, that is exactly what ongoing administration covers — including the departure that happens while you are away.
Microsoft 365 touches most of the environment.
Identity and mail are two of the five control layers. The other three live outside the tenant.
Mail, OneDrive and SharePoint need retention you control rather than Microsoft’s own windows.
Where tenant administration, joiners and leavers, and licence review become somebody’s standing job.
Questions we get before the first call.
Anything not covered here, ask us on the call. There is no wrong question.
Migrations onto Microsoft 365, tenant and licence cleanup, user and mailbox administration, MFA and identity work, email security and deliverability, OneDrive and SharePoint setup, and ongoing administration including onboarding and offboarding. As a defined project or as a standing service.
The goal is no interruption to sending and receiving, and that is normally achievable: mail is copied across while the old system is still live, and delivery is switched outside business hours. What we will not promise is that nothing needs attention on the first morning — signatures, the copier’s scan-to-email, and applications that send mail usually do. We plan to be there for it.
Either works. Plenty of clients keep their own billing and simply give us administrative access. Where we do handle licensing, the sizing conversation comes first — we would rather move you off premium licences nobody needs than add to them.
Not in the way most people assume. Microsoft keeps the service available and retains deleted items for a limited period; after that they are gone. A separate backup with retention you choose is what covers a mailbox from last spring or a library someone overwrote. See Backup & Disaster Recovery.
Usually, and it is normally mail authentication. We check SPF, DKIM and DMARC against every service that legitimately sends as your domain, correct what is missing, and monitor before tightening the policy. If the domain has been used for spoofing there can be reputation to work through as well, which takes longer than a DNS change.
Call (203) 433-2042. We reset and revoke sessions, look for forwarding rules quietly copying mail out, check what else the account could reach, and find out whether any invoice or payment request went out under their name. Then we close the gap that allowed it. You do not need to be an existing client.
Yes, and it is most of what we do here. We start by documenting what is actually configured — administrators, licences, groups, security settings — tell you what we found, and agree what to change and in what order. This kind of configuration drift is common after a tenant has changed hands and grown for a few years.
Tell us what is going on. We will tell you what it takes to fix it.
