Migrating from another email provider to Outlook 365

[anxious_ant]

I've managed to get Yahoo Mail connected to Outlook 365 and it's syncing the new emails, albeit with a delay.

I can live with the delay as the intention is to fully migrate over to outlook email.
However I can't seem to sync existing emails from Yahoo email, I can see the sub folders etc but can't see any emails within them.
Is this expected? If so is there any alternatives?

Do you have Outlook client?

One way is setup your old email in Outlook. Export all items to a PST file. Setup Outlook to new Microsoft 365 email then re-import the PST file and wait for it to sync.

I've used the W10 app to add the Yahoo account and after few minutes it seems that its now syncing the old emails. Sorted
