At what point should you migrate public folders from Exchange 2007/2010 to Office 365 to minimize downtime during a cutover migration? I understand from the guide here that you should migrate mailboxes first but it's not exactly clear.
When I migrate mailboxes over, finalize the migration batch and change the necessary autodiscover records, will Outlook reconfigure itself and continue to display the legacy on-premises public folders?
Just worried that once I have migrated mailboxes, Outlook will stop display the public folders altogether. Would prefer not to end up on the spot in a rush to migrate the public folders when they suddenly vanish unexpectedly.
Obviously not Googling the right questions here, so any help would be appreciated.
