Once you have decided that you no longer need to sync folders in Outlook, there are a few easy steps you can take to stop synchronization.
Stopping the syncronization of folders in Outlook is a quick fix. You can follow the steps below to make it happen in 2023!
What is Outlook Folder Syncronization?
Outlook folder syncronization is when Outlook downloads and stores emails from a server in your Outlook profile.
This allows users to access email, calendar events, contacts, tasks, notes and other data from the same account on multiple devices.
When you configure or add an Outlook.com, Exchange Server, or Office 365 account, Microsoft Outlook creates a synchronized copy of server mailbox items in an OST file (Offline Outlook Data File) on your local machine.
Whenever you open MS Outlook, it immediately tries to connect to the mailbox server and synchronizes the mailbox items to and from the mailbox server.
By default, synchronization is automatic.
However, it may take a while to complete depending on the number of mail items to synchronize and network speed.
For example, if you often receive multiple emails every day with large or several attachments, it may take much longer to synchronize the mailbox items and affect the Outlook performance.
On the other hand, it will also consume a lot of mailbox storage on the server, which isn’t good unless server storage is not an issue.
