Migrating from Apple iCalendar to Office 365? Use GUIDs.

If you're migrating from Apple's calendar offering, you need to map the user GUIDs to target email address in Office 365 / Microsoft Exchange. 

Your mapping text file should look like:

------------------------------------------------------

DB9F0913-DC4A-41CA-8017-6EF5814F01CD, jimi.hendrix@xxx.onmicrosoft.com

FB5CA163-99B8-4436-A906-CC72000E931D, janis.joplin@xxx.onmicrosoft.com

....

------------------------------------------------------

How do you GET the GUIDs?

Via an LDAP Query is most convenient.
