How to Connect Street.co.uk to Outlook: The Complete Email Integration Guide (2026)

There is no single "connect to Outlook" button inside Street.co.uk. Instead, agencies link the two in one of four ways: logging emails manually, leaning on Street's own communication features and apps, building on the Street Open API, or installing an off-the-shelf Outlook integration or add-in from Street's integrations directory. Which route suits you depends on whether you want emails logged against records, replies drafted with CRM context, or both.

Key takeaways

• Street.co.uk does not ship a built-in two-way Outlook inbox sync, but its integrations directory lists Outlook-focused tools, including Embryo for syncing Outlook emails to Street records.
• The Street Open API is available to users of the Street software and covers applicants, tenants, landlords, viewings and more, so custom email workflows are possible.
• Whatever you install, agree logging rules first: which mailboxes, which emails, which record they attach to, and who approves what goes out.

Why does the inbox-to-CRM gap cost letting agents time?

Email is still the default channel for landlords, tenants, contractors and solicitors, while Street is the system of record for properties, tenancies and compliance. When the two are not connected, every meaningful email triggers the same routine: open Street in another tab, search for the sender, skim the tenancy history, write a reply in Outlook, then — if there is time — paste a summary back into Street as a note.

As a purely illustrative example: a property manager handling 50 emails a day, at 90 seconds of context-finding and logging per email, loses 75 minutes a day before any actual problem-solving happens. Numbers vary; the pattern does not.

The bigger cost is silent: replies sent from Outlook that never reach the Street record. When a tenant later disputes what was agreed, or a complaint escalates, the evidence lives in one person's mailbox rather than the tenancy file.

What can Street.co.uk do natively around email and communication?

Street.co.uk positions itself as an all-in-one CRM for sales, lettings, property management and client accounting, and much of its design reduces email volume at source rather than syncing an inbox. Its lettings CRM sends automatic applicant match emails and custom landlord notifications, keeping landlords informed at each stage without anyone typing a message.

On the management side, Street's property management module lets tenants report maintenance through the Tenant App with photos, notifies agents by activity alert and email, and routes approvals to the Landlord App. Street AI adds document handling, such as reading contractor invoices and safety certificates.

What Street's public pages do not describe is a native, general-purpose two-way sync with an Outlook mailbox. Day-to-day inbound traffic — chasers, queries, notices, forwarded documents, contractor quotes — still lands in Outlook, which is the gap the options below address. Feature scope evolves, so confirm current functionality with Street directly.

What are your options for connecting Street and Outlook?

Option 1: Manual logging (copy and paste)

The zero-setup route: read the email in Outlook, find the record in Street, and paste the relevant content in as a note or task. It costs nothing and at very low volume may be enough, but logging depends entirely on individual discipline — and under pressure it is the first thing staff skip.

Option 2: Street's native communications and apps

Before integrating anything, push the traffic you can into Street's structured channels: portal leads through the Enquiry Centre, maintenance through the Tenant App, authorisations through the Landlord App, and automated landlord updates. Every conversation that starts inside Street is one you never need to sync. A large share of correspondence still arrives by email regardless — tenants reply to old threads, landlords forward paperwork, contractors quote by email.

Option 3: A custom build on the Street Open API

Street publishes an Open API for users of its software, with public documentation and getting-started guides; access tokens are arranged through Street's support team. Street's integrations page describes it as a free, open REST API with endpoints covering applicants, vendors, tenants, landlords, viewings and more, plus webhooks for real-time events.

With developer resource you can build exactly the email workflow you want — say, auto-filing correspondence against tenancy records — but you also own the maintenance, so this route suits agencies with in-house technical capability or a development partner.

Option 4: Off-the-shelf Outlook integrations and add-ins

Street's integrations directory spans dozens of tools across data, marketing, communication, compliance and process categories, and it includes Outlook-focused options. Embryo, for example, is listed there as syncing Outlook emails to records in Street.co.uk — automatic logging without a custom build.

A step beyond sync is the Outlook add-in that sits on top of Street. Outlook add-ins run inside Outlook on Windows, Mac, the web, iOS and Android, so they can show CRM context beside the open email. Tools like Lanten take this approach for Street users: the add-in reads the incoming email, surfaces the matching contact, property and tenancy from Street next to it, then drafts an on-brand reply and stages the CRM updates for the agent to approve — nothing is sent or written back automatically.

Which approach fits your agency? A comparison

Approach	Setup effort	What syncs	Where replies are drafted	Control and approval
Manual logging	None	Whatever staff paste in	Outlook, unaided	Full control, but depends on discipline
Street native comms and apps	Low (configuration)	Structured events: enquiries, maintenance reports, approvals	Largely automated by Street	Governed by Street workflows and settings
Email sync tool (e.g. Embryo)	Low to medium	Outlook emails logged to Street records	Outlook, unaided	Sync rules you configure
Custom Open API build	High — developer required	Whatever you build	Wherever you build it	Total, but you maintain it
Outlook add-in co-pilot	Low (Microsoft 365 deployment)	CRM context into Outlook; notes, tasks and updates staged back to Street	Inside Outlook, pre-drafted with CRM context	A human approves every send and CRM write

How do you set it up? Practical considerations

Start with the problem, not the tool. If the pain is unlogged emails, a sync tool may be enough; if it is context-hunting and slow replies, an add-in earns its keep.

A few points that save headaches later:

• Deployment. Outlook add-ins can be rolled out centrally by your Microsoft 365 administrator, so staff do not install anything themselves.
• Access. Anything built on the Open API needs credentials from Street — its developer site directs users to the support team for tokens.
• Pilot first. Turn one branch or one shared mailbox on, run it for a fortnight, and compare logging coverage before and after.
• Data protection. Under UK GDPR, sync business-relevant correspondence to the record it concerns rather than mirroring entire mailboxes, and agree rules for shared inboxes before go-live.

What does good email-to-CRM hygiene look like?

Integration multiplies whatever habits you already have, so fix the habits first. Log emails to the tenancy or property record, not just the contact, so history survives staff changes. Keep one issue per thread where possible, and agree subject-line conventions for anything a contractor must action.

Two categories deserve special care. Maintenance emails carry statutory weight and deadlines, so route them through a defined intake — see our walkthrough of handling maintenance requests in Street. And standardise outbound wording with a shared set of letting agent email templates, so replies are consistent whoever sends them.

FAQs

Does Street.co.uk integrate with Outlook?

Not through a built-in inbox sync, but yes through its ecosystem. Street's integrations directory lists Outlook email sync via Embryo as well as add-ins that bring Street data into the inbox, and the Open API supports custom connections.

Can I log emails to Street automatically?

Yes. An email sync integration can file Outlook messages against the matching Street record, and an Open API build can do the same under custom rules. Approval-based add-ins go a step further, staging notes, tasks and record updates from the email for a human to confirm.

Does Street have an API?

Yes. The Street Open API is available to users of the Street software, with public documentation at developers.street.co.uk, alongside a Property Feed API for powering website listings. Access tokens are arranged through Street's support and API teams.

Which versions of Outlook support add-ins?

Outlook on the web, the new and classic Windows apps, Outlook for Mac, and Outlook mobile on iOS and Android all support add-ins. The same add-in follows staff between the desk and viewings, though exact feature support varies by client.
