Whenever, the PST file size is about to reach 2 GB, Outlook stops accepting mail data and other mail operations couldn’t be performed. The PST file stores approximately 1.82 GB data which is lesser than the exact maximum value of 2 GB.

The message looks like:

"The file <file_name> has reached its maximum size. To reduce the amount of data in this file, select some items that you no longer need, then permanently (shift + del) delete them."

If you are using the operating system older then Windows XP SP1 then Outlook doesn’t even display any error message but stops accepting email messages. You need to obtain the latest service pack of Microsoft Office XP to resolve this problem.
