Simply Dynamics leading the way in Microsoft Dynamics Nav

MIBUSO

In our opinion this is the premium Dynamics Nav user group. Not an official Microsoft site but offers a wealth of both technical and commercial information.

Dynamics User Group

The forums are not as active as in MIBUSO but still a good site for both user and commercial content.

Community Dynamics

This is the official Microsoft sponsored site. Can be difficult to find what you are looking for but does contain a wealth of information.

Customer Source

CustomerSource is a password-protected site for customers using Microsoft Dynamics and related business products, provided as a benefit of a service plan. Use it to search the knowledgebase, download updates, view online training and find other information resources virtually 24 hours a day.

Microsoft Dynamics Forums

A site that servers the complete Dynamics product family. This is a smaller forum site for Dynamics Nav users.
