Due to various shortcomings in Zoho Mail, users choose to migrate to Office 365. The methods outlined below will help users move their Zoho Mail email data into Office 365 efficiently. Let’s begin one by one.
In this method, we use the IMAP protocol to transfer emails from Zoho Mail to Office 365. Moreover, this method is best suited for businesses that prefer migrating emails without downloading any extra tools.
Follow the instructions below to start the process:

| Port | 993 |

Limitations: It does not migrate contacts, calendars, or tasks. This approach takes a lot of time while migrating large amounts of emails. Manually entering incorrect details will cause this method to fail.
The MS Outlook will act as an intermediary to transfer Zoho emails to Office 365. We will configure both accounts in Outlook and then start transferring the emails.
Follow the step-by-step process to begin moving emails:
Step 01: Export Zoho Emails to a PST File
Step 02: Import PST File into Office 365
