Public Folder is an essential feature of Exchange Server, and it contains the shared resources useful for multiple users in an organization. With the help of Public folders, users can collect, organize, and share data. So, it can be termed as the collaboration feature of Exchange Server. The following are the Outlook clients where you have public folders –

• MS Outlook configured with Exchange Server.
• Outlook on the Web (since Exchange Server 2016).
• Outlook for Mac for Office 365.
• Outlook for Mac 2016

When you want to migrate your on-premises Exchange data to SharePoint, then the public folder is an important consideration for you. There is no direct option to migrate the Exchange Server public folder to the SharePoint. So, you will have to go for different kind of methodology where you create PST file, copy the public folder data to PST, and migrate the PST to SharePoint. Let’s go through the process in detail –

Step – 1. Start the Outlook application which has an account configured with Exchange Server. Here create a new Outlook Data File.

Step – 2. The second steps require copy-&-paste of the items from the public folder to the newly created PST file. The advantage of copying the objects from a public folder is that if there is an error in the PST migration, then your data will be safe at the original public folder.

Step – 3. After copying the items into PST file, you can migrate it to SharePoint. Open your SharePoint account and go to the document library. When you open a library, then the library’s location is presented in the URL. You need to convert the URL into a proper universal naming convention (UNC) format. When you change the URL into the UNC format, it becomes suitable for your Public Folder data. Now, you can drag-&-drop data from the PST file. After migration, refresh your web browser and see your data there.

Limitation of Manual method.

The simple drag-&-drop method is simple to perform. But it also has multiple limitations which can affect the performance of migration –

• It can migrate only a small amount of data.
• It cannot migrate permissions.
• There is a chance of data deletion and corruption.
• There are no filtering options.
• There is no way to verify the migration.
