Question : How large can an Outlook.PST and Archive.PST file be?

Hello Experts,
What happens when an (2003) Outllook.PST and Archive.PST grow to 1.5GB+ in size?  Are there Limitations?

Answer : How large can an Outlook.PST and Archive.PST file be?

Hello zwig2002,

It depends on the format of PST file. If you are using Outlook 2003 format PST, unicode, the size limit 20 GB.  If you have copied  Outlook 2002 PST file to Outlook 2003, the format is ansi and limit is 2 GB.

So to answer your question directly, no, there is no program limitation if your outlook.pst or archive.pst grows to 1.5 GB.  But the larger the PST, the more likely it will get corrupted.  Gmail reads and writes to the file all the time. I always advise users to keep the PST below 1 GB for operational reason.

Hope this helps!
