Native Approach to Transfer Office 365 Emails to iCloud 

Unfortunately, there is no direct method to migrate Office 365 data to iCloud manually. According to the recommendation, it is necessary to perform an export process to transfer email messages into the PST format and then import or move the data into iCloud using Apple Mail software. Such a migration is time-consuming and could create some inconsistencies. Below is the complete step-by-step process to export Office 365 to iCloud manually. 

Step 1: Export Emails from Office 365

The following list represents manual steps to export mailbox information:

1. At first,  launch the Office 365 program on the computer.

2. After that, log in with valid credentials.

3. Further, open the File tab and then choose the “Open & Export” option.

4. Following that, select the “Import/Export” option. 

5. From there, pick “Export to a File.”

6. Once done, choose the Outlook Data File (.pst).

7. Select mail folders that you want to export.

8. Define the location of the PST file.
