However, if you start experiencing issues such as slow performance, interruptions, or delays while sending, receiving, or deleting emails, it’s often an indicator that your data file has become sluggish. This slowdown is typically attributed to the growing size of the PST file. A PST file can house multiple mailboxes and is capable of accommodating several gigabytes of data.
