User Query:<\/em><\/strong> We are planning to migrate nearly 600 shared mailboxes from Exchange to Microsoft 365. Most of them have Full Access, Send As, and delegated permissions assigned to multiple users. My biggest concern is losing mailbox permissions or breaking user access after migration. What is the best way to migrate shared mailbox to Office 365 while preserving permissions, folder structure, and mailbox functionality?<\/em><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
