Dear Experts,

Please advise on the best way how to resolve the following technical issue.

Current Setup: A small company consists of 2 designers and 1 secretary. All of them have hosted Microsoft Exchange Server 2007 e-mail accounts, and Outlook 2007 on each computer. Each of the designers has an iPhone linked to their MS Exchange accounts. Using Outlook 2007 on her computer, a secretary inputs appointments and contacts into one calendar in the Public Folders. From there this information is being replicated into personal calendars of each of the designers (using third party software called Add2Exchange), and from their personal calendars it is being pushed by activesync to their iPhones.

The problem with this setup is that Add2Exchange service periodically hangs, and the whole thing stops working until it (Add2Exchange service) is restarted - the exchange hosting company says that company that made Add2Exchange does not release anymore fixes and thus there is no way to fix this issue other than manual restarts each time. Obviously this frustrates both designers very much.

Can you recommend a different, more stable way to achieve this goal of having 1 calendar being pushed into multiple iPhones? I was exploring sharepoint options, but am not sure if it is possible to synchronize 1 sharepoint calendar to multiple iPhones. Thank you in advance!

Here is the diagram how it works now:

The earlier versions of Add2Exchange had a problem recovering from events like rebooting the exchange server in the midst of the sync process. Since WMI over RPC was used, the wmi call would hang. The fix for this was to reduce the number of WMI calls and to time out the call. Having your service provider upgrade to the latest release will fix this problem entirely. If there are still hanging issues, there must be something else in the mix. To mask the issue, an obvious fix would be to have a timed execution or scheduled event of the stop and start executable, located in the /service restart directory. If you still have issue, escalte this and contact technical support at 800-837-8636 and will they will investigate and fix the issue for you.

The hosting company is incorrect. There are new builds for fixes and responses to Microsoft changes almost once a month, on the 15th or so and these releases have been ongoing for several years. There were several releases after working directly with Microsoft resulting in some service packs to Exchange and CDO. Please ask your hoster to upgrade accordingly.
