The process of compacting an oversized Outlook PST file is carried out to make the PST file size small. As a result, this improves the performance of MS Outlook and users can perform the different Outlook operations easily. However, sometimes even the simple process of compacting PST file becomes complex and you may face difficulties during process execution. The issues that you may encounter are Outlook running slow, hanging frequently, Outlook taking a long time in PST file compaction or abrupt Outlook closure.
Why Outlook 2007 Compacting too slow including other Outlook versions?
- Large PST file size – If the PST file size is quite large and you have not compacted the file from a long time, the ‘compress PST file’ process may become slow. Also, Outlook may slow down or freeze due to large PST size.
Note – Compact PST file before it becomes too large to prevent the slowdown of PST compact process later on. Schedule compaction at that time when Outlook is not in use or close Outlook at the time of compacting PST file to avoid Outlook freezing or the slow down issue.
- Compacting PST while using Outlook – If you compact the PST file while using Outlook, the PST Compact process may become slow.
Note – Always close Outlook before you begin to compact the large PST file.
