The file size is always at the center of the process. So, the concern about the size of PST files is clear.
As you know, the maximum recommended size for non-Unicode PST files is 2 GB for all Outlook versions, and the maximum recommended size for Unicode PST files varies by Outlook version.
- Outlook 97 -2002 file size was limited to 2 GB and creates a non-Unicode file (ANSI format).
- Outlook 2003 and 2007 were limited to 20GB.
- Outlook 2010, 2013, 2016, and 2019 are limited to 50 GB.
In some cases, however, ignorance of oversized PST files can adversely affect work processes and lead to file corruption. At this point, the user can get rid of it this way.
The default size of PST files is limited and users want to maximize their size. This can be done using a registry value that can increase the size up to about 4 PB (4096 TB) depending on the version of Outlook. But the main question is.
