Software and cloud engineering
Business email and collaboration setup
Configure or migrate Microsoft 365, Exchange Online, Outlook, and Google Workspace with company-owned identities, shared mailboxes, calendars, authenticated domains, and tested recovery.
Primary buyer: SMEs, professional-services firms, and growing teamsThe real constraint
Mail routing, identity, historical data, devices, calendars, and DNS authentication must move without losing messages, weakening recovery, or creating spoofing gaps.
How we approach it
We inventory the current domain and mail flow, design named and shared identities, stage the tenant and migration, then configure MFA, administration, SPF, DKIM, DMARC, clients, calendars, and rollback.
How we prove it
Independent inbound and outbound tests verify Outlook and Gmail delivery, SPF/DKIM/DMARC alignment, delegated access, shared sent mail, calendar behavior, device setup, recovery, and the old-provider exit path.

FAQ
Questions before a pilot
These answers describe how we normally work. Only a signed agreement creates commitments. Website enquiry terms
01Can you take over a codebase someone else wrote?
We will not promise to rescue a system before we have read it. What we will do is a paid assessment: we read the code, run it, and report what we found. Sometimes we can build on what is there. Sometimes part of it, or all of it, needs reworking first. That call is made on which route gets you working software more cheaply, not on what we would prefer to write.
02Do you work fixed price or time and materials?
Discovery is fixed scope and fixed price because it is small and well defined. Production depends on what discovery found: work with known boundaries can be fixed price, work with genuine unknowns is staged so you decide at each gate. We would rather stage it than pad a fixed price to cover risk you end up paying for anyway.
03How soon could you start?
Often within a week or two for a discovery phase, subject to what we already have committed. The fit call will give you a straight answer. If we cannot take it on a timeline that works for you, we will say so on the call rather than after a proposal.
Service focus
Company email that arrives and keeps working
Email is invisible until it lands in spam, or someone leaves and nobody can reach their mailbox. We set up the domain, authentication records, shared role addresses, and recovery so mail is delivered, access is named, and leaving the company is a documented process.

Not quite your solution?
Explore nearby systems or bring the outcome, workflow, and constraints that do not fit a predefined category. Tandemora can scope a custom solution around the real operating problem.
Your version will have different constraints.
Bring the workflow, current system, available evidence, and the assumption you trust least. We will identify the smallest useful next step.
