I found this excellent resource whilst reading the TAO of CRM blog, which is a really good CRM resource by the way
He pointed me towards a link for the CRM 2011 go live check list
It’s a pdf checklist form. it’s written with an eye on the individual internet explorer/outlook settings and also has some great links for resources to help them resolve any problems.
It’s a useful document and certainly wouldn’t hurt you to check this before you went live.
