I don’t use this one as much but I do find that when setting up an Exchange server the 2 GB default limit is far too small when importing PST files.

Set-MailboxDatabase -Identity “Server1MailboxDatabase1” -IssueWarningQuota 209715200 -ProhibitSendQuota 262144000 -ProhibitSendReceiveQuota 293601280 -QuotaNotificationSchedule “Sun.2:00-Sun.3:00″,”Wed.2:00-Wed.3:00”

I’ll also create a best practices checklist for setting up Exchange Servers for the first time because there’s a lot of little things that need to be done.
