IS PST files Auto compact

[Guest]

I wonder is the PST file auto compact by itself on all vesrion of outlook,
or I have to compact it manually to reduce it size.

when mail is deleted and empty from recycle bin, does the pst file size
reduce by itself atually before compacting.

According to Microsoft's Knowledge Base, compaction does occur in the
background when your PC is otherwise idle, but it occurs only when the
deleted area (called white space) exceeds about 20% of the PST size.

Periodically compact it manually. Don't rely on the automated compaction.
