We have a new installation of MS CRM 2011. All of the Rollup Patches have been applied to the installation. The built-in administrative account works fine. We added our first user. However, when we open us the user (a local Domain User), it shows a scaled-down interface. We cannot do anything with the use. We want it to be able to access a calendar, add Tasks & Appointments, etc. When we try to do anything with the user we get the error message "An error has occurred". "Try this action again ...". When we try to deactivate the user, the same message. We understand that we cannot delete the user. Since we cannot deactivate the use we're stuck in a catch 22 loop. We tried re-adding the user , but we get the message that the user already exists. How can we modify the user in question so that it is usable? Screen shots attached.
