Integration is the difference between a CRM people live in and a CRM they copy into after the fact. Dynamics 365 can sit next to Teams, phone, email and custom modules — if each channel writes back to the same customer record.
Email and Teams
Mail should file itself on the contact or the deal. Teams chats about a customer should not vanish in a private thread. Track the customer, not the app.
Telephony
Click-to-call is not the win. The win is a logged call with the right duration, the right person and a next step. If the phone system cannot write that, the integration is unfinished.
Custom modules and AI
Custom apps are fine when they reuse Dynamics data. AI summaries help only if the source notes are on the record. Otherwise you generate confident text from an empty file.
Rule
Every tool that talks to a customer must leave a trail on the same Dynamics form. If it does not, the team will keep a second spreadsheet.
