Exchange Online is Microsoft's business email on its own, without Office apps. It is the simplest way to give staff a reliable mailbox on your company domain. Here are the three plans and how we set them up.
Microsoft PartnerVerify on Microsoft Marketplace →All three give a mailbox on your own domain with Outlook on the web and mobile, calendars, contacts and Microsoft's spam and malware filtering.
A 50 GB mailbox per user, shared mailboxes at no extra cost, and the desktop Outlook app can connect if you already own it.
Right when: Most staff who need email only.
A 100 GB mailbox, unlimited archive storage, data loss prevention, retention policies and legal hold.
Right when: You must keep email for years or protect sensitive data.
A 2 GB mailbox used through the browser.
Right when: Frontline staff who only read and send a few emails.
Exchange Online is the right buy when staff already have Office installed, or only need email. If they also need Teams, OneDrive or Office apps, Microsoft 365 Business Basic or Standard usually costs only a little more and includes far more.

We connect your domain and publish the MX, SPF, DKIM and DMARC records so your email reaches inboxes and cannot easily be spoofed.

Annual commitment gives the best per-user rate and still lets you add users at any time. Monthly commitment costs more per user but lets you reduce seats month to month.
Tenant setup, mailbox and file migration, user onboarding and activation are included at no extra charge on Microsoft licences bought from Proto Link.
We track your renewal date and remind you before it, so prices, seat counts and plans can be reviewed instead of auto-renewing unchanged.
