In Calendar.app, the 'Window' menu should contain entries for all of the
accounts for which the current user has delegate access. Choosing one should
open that calendar in a separate window. To make delegate calendars appear
in-line with the user's calendars, select the CalDAV account in Calendar
preferences, and use the checkboxes in the 'delegation' tab.

Hard to say what might be wrong. It could be stuck, or it could just be taking
a long time. The CalendarServer logs should be somewhat useful here; they are
in /Library/Server/Calendar & Contacts/Logs - specifically access.log and
error.log. You could also use the web developer console in the browser to look
for javascript errors (the webcal client is implemented in javascript).

Attachments are supported in Calendar.app. Select an event, click
"Attachments", then "Add attachment". Attachments are not supported in the web
client.

Ah, timezones. There are at least a few common causes of this problem. Often
times, comparing the event received from Exchange with one generated by
Calendar is all that's needed to reveal the salient difference. To do this, you
can drag an event from Calendar to the desktop to reveal the ics file, then
open that file in a text editor. The iCalendar body might look something like
shown below. I've highlighted in red portions that are especially relevant: the
VTIMEZONE component, which describes the client's understanding of time zones
with respect to things like daylight savings time, and also the DTSTART and
DTEND properties in the VEVENT component, which defines the starting and ending
time stamp for the event *including time zone specification*.
