How to Reduce Outlook Mailbox Size without Deleting Emails?

Most users opt for the Outlook application to send and receive emails, and their mailboxes can become heavier over time. A bulky mailbox can make Outlook slower to open and search. Also, some email services, like Microsoft 365, have a maximum size limit for your mailbox. So, it is necessary to reduce Outlook mailbox size by deleting unnecessary emails.

Moreover, you can also opt for the Cigati PST Compress Tool to keep it at a reasonable size. It helps Outlook work smoothly and ensures you don’t run into storage problems. If you get a message saying your mailbox is too big, you can try deleting emails and folders to free up space.

However, if you use an Outlook Data File or Offline Outlook Data File to store your emails, that file may not automatically become smaller, even if you delete stuff from it. It means you may have to do something extra to reduce its size.

Need to Reduce the Mailbox Size of Outlook

Reducing the mailbox size in Outlook is essential for a few simple reasons:
