It was a busy time for me to be out of the country last week, with the iPhone Software 3.0 release and the new iPhone 3GS. But another product released while I was gone was Documents to Go for iPhone by DataViz. I downloaded it while I was out of town, but I am having trouble getting it to work with my Exchange server.
In theory, the app is supposed to directly connect to an Exchange server to be able to access attachments to e-mail messages, making this the first app to allow you to get an attachment from an e-mail, edit it on your iPhone, and then e-mail the edited document to someone else. But so far I have not been able to connect to my mail server. If anyone out there has found that there is some trick to get this running with your law firm's (or your company's) MS Exchange server, please send me an e-mail at [email protected] to let me know how you got it working. Perhaps there is something minor I just need to tweak on my firm's server to get this working. (DataViz does have this support page for common problems.)
UPDATE: Thanks for your many e-mails offering advice. I was finally able to get Exchange sync to work for this app. First, I made sure that I had all of the Exchange settings set the same way that I have for Mail on my iPhone, which includes, for example, not having the ".com" on my domain. Second -- and thanks to Rachel Lunsford for this tip -- I turned off SSL, even though I normally have SSL turned on for the iPhone Mail app. Third, I turned off Wi-Fi. I find that, for me at least, Exchange support only works if am using 3G / Edge, not when I am on Wi-Fi at my office. (I'll see what happens using Wi-Fi elsewhere, such as my house.) [UPDATE 6/23/09: My Wi-Fi problems are not related to DataViz's app. Something in the iPhone Software 3.0 update has caused the Wi-Fi in my office to not provide connections to the Internet. I'm still researching this bug (and it is one that some others are seeing too, according to Apple's discussion forums), but I don't want to give the impression that the Wi-Fi problem was a DataViz issue.] After these steps, I was able to successfully download an MS Word attachment from an e-mail, edit the file on my iPhone, and then e-mail the file.
If you want to check out this product, for a limited time you can buy it at a discount. You can buy a version that doesn't include the Exchange feature for only $4.99, and the version that includes Exchange support is only $9.99. After June 30, 2009, these prices go up -- I believe that they double, but I don't see this confirmed on the DataViz website. I hope to get this app fully running on my iPhone before June 30 so I can give you my full thoughts before the price increases.
