Office 365 Huge PST file

I have migrated to office 365, I still have my old PST file I need to import, but it's over 20gb , and when I try to import it , it doesn't show it's doing something.
Besides copy each folder one by one, it there a way to import such a big file or split it?

So whats the difference between the archiving that will split the file and a 3rd party that will do it?

If you Archive and Compress, it reduces the size of the main file. It (roughly) comes out the same as Split.
I use Office / Outlook 2016 and it can handle large files, but I still Archive and Compress (Compact) regularly to keep my main file tidy and small.

Does office 365 have a way to deal with huge mailboxes?
Online Office 365 (Exchange) can deal with these files, but it is not recommended - performance and synchronization time for offline Outlook.

I know they have an archiving feature..

have you used it?
I have not use Exchange Archiving but I know it works. I use local Archiving and that definitely works. Archiving is a longer term proposition to be used regularly. I run Archive every 60 days and monthly is not too frequently.

Yes, but the whole idea of having a cloud based (hosted) service is that you will have all of your emails on the cloud, accessible from everywhere anytime.
Archiving for Office 365 Exchange (""in the cloud"") works. I just have not used it.
Your original question was different. "I have a file too big to import" .  So split it up with Split PST or with Archive / Compact locally until it is small enough. Then import. Then set up regular archiving.

Actually, Split PST Software divides your PST file into four ways:

1.) Split by Year
2.) Split by Size
3.) Split by Date
4.) Split by Folder

Additionally, it also allows to save new PST file into ANSI & UNICODE file format.

Hi

You could try the Office 365 Import Service:

We have users that have over 100GB of mailbox data. Their mailbox can host up to 50 GB and their Archive holds up to 100GB.

It works great when using Outlook client but you cannot access Archive from mobile devices.

Thanks
