Migrating to Office 365? Hint: Disable Throttling

Throttling is a wonderful feature to get rid of during a migration.  You have the need -- the need for speed.  Throttling can sometimes be the annoying speed bump or rumble strip that at best slows you down and at worst halts your migration.

Fortunately there's a good guide to how to disable using the user interface on Office 365:  Disable EWS throttling in Office 365 – Exchange Online

We don't re-do work that's already been done -- this is a good, straight-forward guide.

If your interface does not have this option, open "Help" and type in "Increase EWS Throttling Policy."  Should bring up this page and you're good to go.

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

Via an LDAP Query is most convenient.
