I am using Outlook 2007 and recently upgraded from Vista to Win 7 Ultimate.
It was after upgrading I noticed the problem.

I downloaded the file to change time zone but couldn't get it to start. I
got an error "operation failed"
I decided to try something else.
I exported contacts as vcf. .
Deleted all contacts
In Calendar set View by Category
Deleted Birthday Category
Exited Outlook
Imported the Contacts files
Assigned birthdays back to Birthday Category
Observed Birthday entries in Calendar no longer spanning 2 days
That fixed it for me.
Thanks anyways

Did you change the time zone or daylight time setting? try this tool to
fix

You can set the duration to 12 hours if you want but you'll need to open
each event and change it.

All was fine with my Calender and Birthdays until 3 days ago. I opened
my
calender and a majority of my birthdays are now showing multi day
scheduling.
Is there a way that I can change this back to single day scheduling
without
opening each birthday individually?

The time zone or DST setting on the new computer is not the same as on the
old computer.
