Connect Outlook, Teams and Microsoft 365 to Your CRM
If your company runs on Microsoft 365, your customer conversations happen in Outlook, your meetings in Teams and your documents in SharePoint and OneDrive. Your CRM should reflect all of it, without anyone copying and pasting.
Xirgosoft integrates Microsoft 365 with your CRM or ERP through the Microsoft Graph API and Entra ID authentication, so emails, events, contacts, files and chats are connected to the correct customer or deal.
Because many Microsoft 365 organisations have strict security rules, we plan permissions, admin consent and tenant policies carefully, and we support both single-tenant and multi-tenant designs.
We integrate with vTiger, SuiteCRM, SugarCRM, YetiForce, Frappe CRM, Odoo, HubSpot, Salesforce and custom systems.
Why Connect Microsoft 365 to Your CRM
For many organisations, Outlook is where customer relationships are actually managed. Meetings are held in Teams, quotes live in SharePoint and approvals travel by email. A CRM that sits apart from all this becomes a second place to maintain, and teams quietly stop updating it.
A Microsoft 365 integration closes that gap. Emails and meetings are recorded against the right customer, documents are linked rather than duplicated and alerts reach people in Teams, where they already work.
We design these integrations with enterprise requirements in mind: least-privilege Graph permissions, admin consent documentation, support for conditional access and a clear approach to licences and service accounts.
We also help you decide when to use a lightweight sync and when to build a more complete workflow, so the solution matches the size and risk profile of your organisation.

Frequently Asked Questions
Do you use Microsoft Graph?
Yes. Microsoft Graph is the standard way to access Outlook, Calendar, Teams, SharePoint and OneDrive data for Microsoft 365.
Will our IT administrator need to approve it?
Usually yes. Apps that access organisational data typically need admin consent. We document the permissions requested and why.
Does it work with on-premise Exchange?
Microsoft 365 integrations target Exchange Online. On-premise Exchange uses different options, which we can discuss.
Can we replace Outlook add-ins we already use?
We can review them and recommend whether to keep, replace or extend them.
Can Teams be used to approve things from the CRM?
Yes. Approval requests and actions can be surfaced in Teams, subject to the design we agree.
Can you integrate with Dynamics 365 or Business Central too?
Yes. We also implement and integrate Dynamics 365 and Business Central, so the pieces can be designed together.
Do users need to install anything?
Usually no. Most of the sync runs on the server, though we can add Outlook or Teams components where useful.
