Public folders and Shared mailboxes in Office 365: Nutshell

Public folders

A public folder is a feature in Microsoft Exchange Server that allows users to share common files, documents, calendars, contacts, and other data. Public folders can be accessed by anyone who has permission to them and can be useful for teams that need to share information across the organization. However, public folders have some limitations, such as the lack of mobile support, limited collaboration features, and difficulties with external sharing.

Shared mailboxes

A shared mailbox is a type of mailbox in Office 365 that allows multiple users to send and receive email messages from a single email address. Shared mailboxes are often used for team collaboration or departmental email accounts. It can also be used for shared calendars and contacts, and they provide more collaboration features than public folders. Shared mailboxes can be accessed from any device and are easier to manage and secure than public folders.

Why migrate public folders to shared mailboxes?

Public folders are an older technology that lacks some of the features and flexibility of shared mailboxes. For example, public folders are not accessible from mobile devices and do not have the same collaboration features as shared mailboxes.
Microsoft has stated that they will not be investing in new features for public folders in the future, so organizations that continue to use public folders may miss out on new functionality and updates.
Migrating public folders to shared mailboxes can provide a more modern and efficient way for teams to collaborate and share information within Office 365. Apart from this, there are some benefits that the users get while using a shared mailbox as compared to Microsoft Office 365 public folder:

  2. Users can access a shared mailbox from a mobile phone which makes it impossible to access public folders.

In general, this method is not recommended because it involves running complex cmdlets, and there is a  risk of manual errors.

Drawbacks of the manual method

Migrating public folders to shared mailboxes in Office 365 using the manual method can be time-consuming and complex, especially for large organizations with a lot of data. Here are some of the limitations and challenges of the manual method:

  • Complexity: The manual method involves exporting the data from public folders to a local file, such as a PST file, and then importing that data into the shared mailbox using Outlook or OWA. This process can be complex and time-consuming, especially for organizations with large public folder structures or a lot of data.
  • Potential for data loss: The manual method requires users to manually select and export the data they want to migrate. This can lead to data loss if users forget to export important data or select the wrong data to export.
  • Limited automation: The manual method requires users to perform migration tasks manually, which can be time-consuming and error-prone. There is limited automation available for the manual method. Hence users may have to repeat tasks or troubleshoot issues manually.
  • Lack of reporting: The manual method does not provide detailed reporting or logging of the migration process, which can make it difficult to troubleshoot issues or track progress.
  • Dependency on end-users: The manual method requires end-users to perform some of the migration tasks. This can lead to delays or errors if users are not familiar with the process or forget to perform the required tasks.

Overall, the manual method can work for small organizations with simple public folder structures and limited data. However, it is not recommended for larger organizations or more complex migrations. In those cases, it may be better to use a third-party migration tool to automate the process and reduce the risk of data loss or errors.

Tips for optimizing the migration process and avoiding common pitfalls

  • Plan the migration carefully and consider all the factors involved, such as the size and complexity of your public folder structure, the number of users involved, and the migration method you will use.
  • Test the migration thoroughly in a non-production environment before performing it in a live environment.
  • Communicate the migration plan and any changes to users and stakeholders to minimize disruption and ensure a smooth transition.
  • Monitor the migration closely and have a backup plan in case of any issues or unexpected challenges.
  • Consider using third-party tools to simplify and automate the migration process and avoid potential errors or data loss.
