To manually
Migrate ProtonMail to Office 365, you can use ProtonMail’s Bridge app to connect to an email client like Outlook via IMAP. First, download and set up ProtonMail Bridge, then configure Outlook using the provided IMAP settings. After that, manually export your ProtonMail emails to PST files and import them into Office 365 using Outlook’s import feature. However, this manual process can be complex, time-consuming, and error-prone, especially with large mailboxes or attachments, as well as potential data loss risks.
An easier alternative is using the Migrate Cloud Data IMAP Mail Backup Tool. This tool simplifies the process by directly connecting ProtonMail and Office 365 using IMAP protocols, automating the transfer of all emails, folders, and attachments. It eliminates manual intervention, reduces errors, and ensures a faster, more secure migration process. It’s ideal for both individuals and organizations looking for a hassle-free way to move their ProtonMail data to Office 365.
