New email sync issue
When migrating from an existing POP mailbox I will make the required DNS changes, export to PST once the MX records have propagated and configure the new O365 mailbox under a new Outlook profile before importing the email from the PST file.
I have noticed however that until the sync up to Exchange Online has completed, the user does not see any new emails despite them arriving in the mailbox and being visible in Outlook on the web.
Has anyone else noticed this issue? It's a shame you can't limit/pause the synchronisation of older emails or better still, schedule that process for a more suitable time. It seems strange that it prioritises that over the arrival of new emails while it sits there 'Updating Inbox' or 'Updating Sent Items'.
Thanks

How are you importing the PST? If it's directly via Outlook, that practically "locks up" the application until the upload is complete, so what you are seeing is expected. You can upload it via the O365 Import service or 3rd party tools. Or just use OWA for the duration of the import :)
I am importing via Outlook. Don't you think it would better if you could pause the sync of older emails or at the very least, it prioritised syncing new emails over older ones?
I looked into importing via the O365 Import service. Can you be selective about which folders to import and can you map the folders in the PST to the folders you want them to be imported into in the mailbox? I only found the option to import everything to a new root folder called Imported which is far from ideal.
Outlook on the web (aka OWA) is a workaround, but there are some limitations to this - lack of some third-party add-ins being one.

- You could try to migrate the PST directly to cloud (Admin Center -> Setup -> Data migration). This way the Outlook would not be blocked as the migration would take place in the cloud.
