Microsoft Outlook: Change delete recurring events appointments without losing history

Google calendar has one very good facility- if you want to change details about any appointment, which is part of recurring event series, it provides options to change a) only that event, b) all events in the series, c) only the future events.

This option c) is not available with Outlook. So for example, if you want to shift all the future events by 1 hour later (lets say to handle winter light saving changes), the timing for all the past instances would also get changed. Also, you would end up losing notes & any other changes you might have put in them. 

Solution? Till Microsoft incorporates this feature, a bit complicated procedure is needed. This post gives the  details, a little update version would be as the following.

i) Make one temporary Outlook Calendar (Temp). 

iii) View your regular Outlook Calendar (Regular) in Category view. This will show all events as a list.

iv) Drag the event-sereis (for which future events need to be changed) to Temp. 

v) Open Temp and export it to one MS-Excel file Excel).

vi) Open Excel. It would have all events in the series as separate rows. Change the particular entry (timing for example) for future events. Or better delete all future events and later make a new series for them in Outlook. Save Excel and close it.

vii) Import the Excel into Temp calendar.

viii) View Temp in category view. Drag the events into Regular.

ix) Delete Temp and Excel.
x) Create a new series for future events with changed timing & other details.

Note: 

1) If you use Calendar in your local PST, then the global Calendar of your exchange account can also be used as Temp- or vice versa. This would save the time of creating another calendar and then later deleting it.

2) The post mentioned above gives almost the same procedure except that it doesn't use Temp calendar. The problem with that method is that all other appointment series also get into Excel and in the process are broken into individual appointments when imported back.

I hope this helps others. If you can find some other less cumbersome process, please let me know in comments. And lets pray that MS makes this change in Outlook, the Net is full of such requests already.
