How to switch from GoDaddy to Office 365 manually?

Try this to easily transfer godaddy email to office 365:

Go to Microsoft Exchange Server Admin Center and navigate to migration from receipts.
Click on the + sign to add and choose Migrate to Exchange Online.
Select IMAP migration as it is supported by both the email systems.
Enter the server details on the IMAP configuration page.
Create a batch for the migration.
Select the users that will be notified once the process is completed. You will know when the status of the batch changes from 'syncing' to 'synced'.
This method works only for email. However, in most cases, there are contacts, calendars, and other items that also have to be migrated. This can be done by exporting and importing data using PST files.

How to Export contents on IMAP enabled mailbox to PST files

If you are using GoDaddy along with Outlook, follow the process below to export calendar/ contacts and other items into PST files.

In Outlook, select Import/Export from files and select "Export a file" and hit OK.
Select Outlook Data File (PST) and click OK.
Select the appropriate folders and subfolders and click Next.
Select the folder to save the newly generated PST file and click Finish.
Setup the Office 365 account for Outlook

Navigate to the Control Panel, select Mail, and click Add in Show Profiles.
Select the option ‘Manual Setup or additional server types.’ and hit Next.
Select Office 365 in the next window to add all the Office 365 accounts automatically.
Import the PST files into Office 365

Navigate again to the Import/Export option on Outlook and select 'Import from another program or file.'
Select the PST file saved locally and Import it into Outlook.
The older GoDaddy account can be removed once contacts, emails, and calendar items have been imported into Outlook.
Delete the migration batch once the process is complete.

Hope this helps.
