You can use your Peek with Microsoft Exchange 2007. It requires turning on WebDAV though — by default that setting is off.
Here is a fully detailed walkthrough for your company’s IT guy.

Questions
How quickly will I receive emails on my Peek?
With the Peek Pronto, Gmail is just about instant if you have enabled IMAP. Hotmail, Live, and MSN will be the same in late June and AOL in July. Yahoo! will follow shortly thereafter. Email from accounts that aren’t instant (POP3, ISPs like Comcast and Verizon) should arrive every few minutes.
With Peek classics the time can vary from 5 to 10 minutes and older versions of Peek between 5 and 15 minutes.
How do I view attachments?
Peek Classic currently supports displaying image attachments that are .jpg, .png, .gif and .bmp.
Peek Pronto supports viewing images, PDF, and Word docs.
To view an attachment on your Peek, just select “View attachment” from the menu while you are reading an email.
Even if an attachment can’t be viewed on your Peek, all attachments will be preserved when forwarding email.
To view attachments on your Peek, simply do the following:
-Open the email with the attachments you would like to view.
-Open the menu, select “View attachments” option
-Scroll over particular attachments and select “View attachment”
Some of my emails don’t show up on my Peek, but I can see them in my Inbox online. What gives?
This may happen when email you receive is automatically marked as spam. Since we try to keep your Peek Inbox uncluttered, your Peek won’t receive anything marked as spam. If you’d like to remove this filter, turn off spam filtering for your email account.
Another common reason emails are not delivered to your Peek is if you also use another third-party client like Outlook or Thunderbird to read emails. If you do, make sure that you’ve chosen to “Leave a copy of mail on server” in your third-party client.
If you have trouble finding your account’s spam settings or if you’re still missing email on your Peek, please call us at 877-677-PEEK and we’ll be happy to help you out.
Is there a limit to the size of emails I receive on my Peek?
Yes, we impose a 12k character limit on the size of emails that can be viewed on your Peek. Although it’s a pretty high number, you might find that you reach it for those emails that are abnormally large. These emails are best viewed on your computer.
There is also a 4k character limit for emails sent from your Peek.
We also impose a limit of 10MB on the size of attachments (2MB if attachments are received using MSP) that can be received and forwarded by your Peek. If a single email contains attachments that exceed this limit, all attachments beyond the limit will not be visible on your Peek.
If I read or delete an email from my Peek, will it sync with my online account and vice versa?
Currently Peek does not support two-way syncing, but this is something we’re working on.
Can I create folders on my Peek?
No, but Peek comes with the following folders pre-loaded: Sent mail, Saved mail, Drafts, and Trash.
Does Peek support HTML and rich text emails?
Peek reformats HTML and rich text emails into plain text so that they’re easy to read on the go.
How do I insert a plus (+) sign or other symbols into an email?
To insert symbols like the plus sign, just pull up the main menu and click on Insert Symbol. A small horizontal bar on the bottom will appear at the bottom of the screen with all the symbols you can add—including bullet points and
