Compact and reduce mailbox size in Microsoft Outlook
Compact and reduce mailbox size in Microsoft Outlook
Microsoft Outlook, the client for email services, saves email and attachments offline. As you receive and send emails, the size of the database keeps increasing. While it makes sure that you can access emails when not connected to the internet, it also means that the size of the mailbox keeps expanding. The disadvantage of having a bigger mailbox is that it slows down the experience. It takes longer to open and search for anything. It means unless you reduce the mailbox size in Microsoft Outlook, you cannot send or receive any email.
