Who this is for

Web designers and agencies that manage client Microsoft 365 accounts and need expert help with setup, problems, or domain changes.

Client bought Microsoft 365 but you have never set it up before
M365 setup means navigating the admin portal, configuring Exchange, adding the domain, updating DNS records, and setting up user accounts. We handle the full setup in one engagement.
Client email stopped working or is going to spam after a DNS change
A DNS change that overwrites MX records, SPF, or DKIM will break Exchange Online email immediately. We audit the current DNS, find what changed, and restore mail flow in a single session.
Outlook is showing a password prompt on loop or sync errors
Cached credentials issues, Autodiscover misconfiguration, and MFA enrollment problems all cause persistent Outlook errors. We diagnose the exact cause and walk through the fix.
Client is switching to a new domain and needs Microsoft 365 updated
We add the new domain in the admin center, update all DNS records, change the default domain, update user UPN addresses, and keep the old domain attached as an alias.
You are setting up or fixing M365 for a client already on Cloudflare
Cloudflare DNS requires specific handling for Microsoft records. Autodiscover CNAME conflicts and MX proxy settings are common mistakes. We handle DNS correctly for Cloudflare-hosted domains.
A previous setup attempt left things partially configured or broken
Incomplete M365 setups with missing DNS records, unverified domains, or half-migrated accounts are common. We audit the current state and complete the setup correctly without starting over.

Everything Microsoft 365, handled for you.

Setup, support, and domain changes all covered. If it involves Microsoft 365 for an agency client, we handle it.

Tenant Setup and Domain Verification
Microsoft 365 tenant created, domain added and verified in the admin center, and Exchange Online configured so mail routes correctly from day one.
MX Records and DNS
All required DNS records added including MX, Autodiscover, and any Microsoft-specific records needed for the tenant to work correctly with the domain.
SPF, DKIM, and DMARC
Email authentication configured so outbound Exchange mail reaches inboxes. Includes blocklist checks when outbound delivery is the problem.
Users, Mailboxes, and Distribution Lists
All users added, shared mailboxes created, distribution groups and security groups configured to match your client’s org structure.
Email Migration
Existing mail migrated from Gmail, cPanel, or another Exchange environment without data loss. Scoped separately for large migrations with many mailboxes.
Outlook and App Setup
We help users connect Outlook desktop and Outlook mobile, and diagnose and fix sync errors, password prompts, and Autodiscover issues.
Domain Changes
New domain added and verified in M365, DNS records updated, default domain changed, user UPN addresses updated, and old domain kept as alias so no existing mail is lost.
User Lockouts and Access Recovery
MFA issues, locked accounts, admin access lost, security defaults causing unexpected lockouts. We work through what access remains and recover what we can.
Admin Center and License Issues
Suspended services, license assignment errors, missing features, and admin console errors that make no sense. We find the cause and get the tenant into a working state.

Frequently Asked Questions

Common questions about our Microsoft 365 services.

Do you work with the Microsoft 365 admin center and Exchange Online?
Yes. We work directly inside the Microsoft 365 admin center to handle tenant configuration, user creation, mailbox setup, and DNS records. Exchange Online is part of most business setups and we configure mail flow, shared mailboxes, and distribution lists as needed.
Can you migrate email from Gmail or Google Workspace to Microsoft 365?
Yes. Gmail to 365 migrations are one of the more common setups we handle. We switch the MX records to point to Microsoft 365 first so new mail starts flowing immediately, then migrate historical email from Gmail into the new mailboxes. The scope and timeline depend on the number of mailboxes and how much history needs to be moved.
My client’s email stopped working after a DNS change. Can you fix it?
Yes. DNS changes that wipe or overwrite MX records, SPF, or DKIM will break Exchange Online email immediately. We audit the current DNS, identify what changed, and restore mail flow. Most of these are resolved in a single session.
Outlook is showing a password prompt on loop and nothing works. Can you fix that?
Yes. This is typically a cached credentials issue, an Autodiscover misconfiguration, or an MFA enrollment problem. We diagnose the exact cause and walk through the fix. Submit a ticket with the error and what device and version of Outlook they are using.
Will email go down during a domain change?
We work through the DNS changes in a specific order to keep disruption minimal. Mail may experience a short delay during propagation but we monitor it throughout and the session does not end until everything is flowing on the new domain.
What happens to email sent to the old domain after the switch?
We keep the old domain on the account as an alias. Any mail sent to old addresses still lands in the right inbox. We recommend keeping it attached for at least 90 days.
