I definitely advise anyone using Outlook to go back to the version 1 of iCloud control panel (ICC). While I didn't have the mail problem (I use Yahoo with POP), boy did it hose up my Outlook calendaring. Issues you should be aware of with version 2.0 and Outlook (I'm using 2010)
- While version 2 of ICC fixed the annoying warning message about having a reminder, I found that it DISABLED all of my reminders on existing events. Even turning the reminder back on wouldn't cause Outlook to fire off a event reminder. The only fix was to create new events. And if you change that event in Outlook, the reminder, even if updated, won't fire. I will note the reminders worked fine on the iPhone despited the Outlook problems. Version 1 of ICC preserves reminders just fine in Outlook.
- Someone in Apple decided that since the iPhone and iCloud don't support rich text (RTF) in their calendar note field that they should then disabled it in Outlook. So they created a NEW outlook calendar form that does just this. That's annoying since ICC V1 simply stripped out the formatting. The new Outlook cal form apple created won't even let you hit escape to get out of it. You have to click the "x".
- With ICC v 2, if you blank out a Outlook event date, it will revert to the Year 2000 (or worse, I had one got to the 1600's). The correct behavior is to revert to the current date or later, which ICC V1 does.
- After upgrade to ICC v2, my iPhone stopped downloading from the iCloud. Apple support really tried to figure this out and we did get it working by deleting iCloud from the phone. However, it kept re-occurring. Turns out it was a data corruption caused by the ICC v2 upgrade.
My ultimate solution was to uninstall ICC v2, clean out everything from the iCloud and iphone, then retrieve backups of my Outlook cal/tasks/contacts. Once I installed ICC V1, all was well again. ICC v1 does't support photo stream sharing, but it sure works better with Outlook than does v2.
If you need v1, plenty of places on the web have it. I'm not going to post them since I suspect apple will not approve.
