If you are experiencing similar issues, do not worry anymore as we have gathered some tricks that tackle this problem easily.

What does it mean when the Outlook data file has reached the maximum size pst?

Microsoft Outlook has an option that allows users to store email files and folders as offline files. These files are called Outlook data files and carry the extension .pst.   When this error occurs, it means you have exceeded the default size limit of your Outlook data files, and it would not be able to store further emails. A Microsoft Outlook mailbox can have a maximum size of 100GB, whereas .pst files have a 50GB maximum file size limit. The.pst file may still be added to your Microsoft Outlook mailbox if either of these limits is exceeded, but you won’t be able to open it, nor will you be able to share the .pst file. Regardless, you can explore the advanced solutions provided in the next section to know how to fix the issue.
