Although various companies are shifting toward SharePoint Online, Teams, and automation in their Office 365 tenant, Public Folders are still very much used by companies to store different kinds of data. Also, the Public Folders in Office 365 (Exchange Online) are still supported and used. Migrating a mailbox from on-premises Exchange Server 2013 or 2016 to Office 365 would not be a difficult task, but it might be a little bit trickier and more complicated to export and import Public Folders into Office 365. In this article, we will be going through the process of migrating Public Folders from Exchange 2013 to Office 365. For Exchange Server 2016, the process is same.
Procedure to Migrate Exchange 2013/2016 Public Folders to Office 365
It is to be noted that not all Public Folders are compatible. You need to rename the Public Folders which contain any backslash or forward slash in the name. If you have many Public Folders, it will take a lot of time but by using PowerShell, you can automate this part.
This should not return any results if you do not have any folders with a slash. All you need to do is rename the folders if any are found. Next, you need to know if there were any attempts of migrations, done from your staff, from an Exchange Server which was inherited from another company.
Although the change is instant, it might take up to 2 hours until it is propagated to all the users. Once this time has passed, you can finish off the migration by using the Complete-MigrationBatch Public Folder Migrationin the Exchange Online PowerShell.
After all the Public Folders have been migrated, you need to unlock them by using the below command in the Exchange Online PowerShell.
Set-OrganizationConfig -RemotePublicFolderMailboxes $Null -PublicFoldersEnabled Local
As you can see, this is a lengthy and complicated process that could have a number of fault points. It will take a considerate amount of time to complete and is not a hundred percent neat. As an alternative, you can look at third-party applications, such as Stellar Converter for EDB. The application can migrate public folders from exchange 2013 to Office 365 as well as from Exchange 2016. The software can open the EDB file of any size and of any version of the Exchange Server. It can export Public Folders to PST or directly to an Office 365 tenant.
