I encountered an odd problem while working with a customer that was porting from Lotus Notes to Office 365 (Exchange) and ended up creating a new tool called the Outlook Calendar Cleaner.
The customer had a mixed environment of Mac and Windows and in certain conditions appointment items were disappearing on the Mac Office Outlook calendar, but still appearing in Outlook Web Access (OWA) and if the delegate was in Windows, they would still see the appointment on their view of the owners calendar.
The issue turns out to be that in the conversion a multi-line subject in an appointment item (supported in Lotus, but not in Exchange), has the new line character converted to a start of text (SOT) character or ASCII code 0x02. The problem is that this is an invalid character in XML and the Exchange Web Services implementation on Mac O/S X does not properly parse this character. This causes the process to hang and all appointments which were being imported on that thread are not copied over. Net effect – they appear to be missing in Mac Outlook.
So, I created a tool to correct the problem. The Outlook Calendar Cleaner is a very specific tool targeting this problem. You can to open the users Exchange Account (Office 365 account) in Outlook 2010 for Windows and run the tool in Windows and it will clean any appointments found to have this special character.
I have posted the Outlook Calendar Cleaner tool on Codeplex (along with the source code). Here:
