Certificates in Exchange 2007

Lots of our customers, partners and sttudents has this problems while inplementing Exchange 2007 (With its client) - certificates.

Question now is, what certificate used in Exchange 2007?

  • ActiveSync
  • Autodiscover
  • Internet client, like POP3 and IMAP4 client access
  • Outlook Web Access
  • Outlook Anywhere
  • Edge Server

Now, since there are so many components, can we use all with the same name? The answer is no. Thus, in Exchange 2007, we will need certificate that support wildcards name. However, by default, when installing Exchange 2007, a self signed certificate is installed - can we use it? Yes, you can, but we will not recommend as it will not know the Internet domain name you are going to use, not supporting SAN extension supports (X.509 standard).

After knowing this, choosing a right certificate in Exchange 2007 is important. Knowing Exchange 2007 client that support wildcard certificate is also another challenge. For what we know as for now, the following client do support:

Outlook Express, Outlook, Internet Explorer (OWA)

However, clients running Windows Mobile 5.0 do not support secure connection to servers where wildcards are used in the certificate. Do take note.

Cheers

Fortunately quite long I know about one nice application-undelete outlook express messages,it is free as far as I remember,tool has no one facility,it was helping my friends and myself many times,utiltiy keeps all messages in several files with dbx extension, so, you will be unable to get an important document, without opening your mailbox, if it will be needed,compatible with Windows NT, Windows 2003, Windows 98, Windows Me, Windows XP, Windows XP SP2 and Windows Vista,keeps your email in dbx files, by doing so, user mailboxes are splitted into several files: Inbox.dbx, Outbox.dbx, Sent Items.dbx and Deleted Items.dbx, that coincide with Inbox, Outbox, Sent Items and Deleted Items folders,can also select several files with eml extension and drag them into Outlook Express for undelete Outlook Express email.

Many places along this path, malwarekeyloggers and Rats or simply keyboard hookers can be physically or remotely installed by hackers to gain access to computer users' personal and financial information. The first step has to be downright sneaky.
