How to move Exchange Server 2007 public folders over to office 365 Exchange

I currently have an SBS2008 server environment where we are actually using the exchange server public folders. This database is about 30 GB in size already.
- We are going to be upgrading our server hardware and moving to either server 2012 R2 or server 2016 operating system
- we are also moving from exchange server to office 365 per exchange email will

My question is: by going to office 365 four exchange email, what is the best way to maintain and support Exchange public folders

I think you have no choice like export public folder to PST file then import it to O365 or open pst file in new Office and copy over data manually using Outlook.

To export public folder to pst file you can use ReliefJet Essentials for Outlook.

You can also use Outlook itself to Export Public folder to PST file but this must be Outlook 2010 or higher with UNICODE pst file format since other formats are size limited.

From Outlook 2010 you can go to File / Open / Import

Select Export to File
then Outlook Data File (.pst)
Then you going to be able select public folders (select sub folders check box)  and click Next to start export.

I thought that was the best option - to export it into a PST file. The idea is to share it with everyone on the network

Your easy and best option would be export and import to a working outlook as commented by Tom.
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Another option to export Exchange Public folders and mailboxes is Kernel for Exchange Server recovery software.

i got confused here. if your are moving your Exchange services in to the cloud, what's point for upgrade the hardware for internal server? just to upgrade the remaining Windows server features?
Andreas GieryicComputer Networking, OwnerAuthor Commented:
My firm is an engineering firm. All of the server and client based applications upgrades are no longer supported on this older SBS 2008 operating system. Therefore, I need to replace the server hardware to support the latest server operating system. With that said, it's not cost-effective to install exchange server 2016 locally. This is why we're moving to the cloud for exchange

My concern is, what is the best way to share the public folders once exported to a PST file.
Do I create another office 365 email account and give that access to all users?   I need to be able to lock down certain folders.
Tom CieslikIT EngineerCommented:
You can create Public Folder in O365 and give people access to it, the connect one (administrator outlook account) to O365, open PST file and copy over all information from PST to Public Folder in cloud.
You should do it overnight since 30 GB is a lot of informations.
