What did I learn about Dynamics CRM today?

The XRM User group is extremely worth the time investment. If you have not listened to one of their webinars - do so! There are numerous ones to choose from.

Validation that if you are going to add any form, custom screen, Silverlight gadget or other types of style sheets you really should aim to make those look like CRM. The User interface and interaction should be consistent. (the word on the wind is that in the next release of the SDK you will have some available to work from)

When synchronizing Outlook Contacts to CRM the system uses the default Address 1 so if you replace it don't forget to build in the Outlook mapping. Why would you ever want to replace address 1? Perhaps you have more than 7 address fields.

Microsoft took out the ability to delete pre-configured system views on entities. Why? and when did this happen and can you hide the ones you do not want to use?

Attachments are all over the place.

The resource center is a great example of how you can add a custom Information Center of business oriented "help".

Developers should always spend a tiny bit of time reviewing some of the test cases. It is eye opening for both parties.
