# Exchange 2010 Mailbox Database HTML Email Report
# Author: Thiyagu14
# Date Jan 28th 2010

# 3. Database file path
# 4. Number of users in the Database.
# 5. Amount of Whitespace
# 6. Top Mailbox in the Database and the size of it.
# 7. Last Backup time and days since last backup.
# ###################################################################################
# It then generates HTML Files for this.
# You can setup Threshold in the script,below are the items which can have threshold
# 1. Number of Mailboxes
# 2. Database Size
# 3. How old a Backup can be
# 4. Top Mailbox Size

# It will be marked as red in the HTML.
