I am currently facing an issue with my old ANSI PST file in Outlook, which has reached the 2GB size limit. Because of this, I can not add new emails, and Outlook sometimes freezes or shows errors while opening the PST. I came to know that upgrading to Unicode PST can fix this limitation since it supports larger file sizes. Can anyone guide me on how to safely upgrade or convert my existing 2GB ANSI PST file into a Unicode PST file without losing any emails or data?

If you are using an older version of Microsoft Outlook, like Outlook 2002 or earlier, then you might have faced the problem of a 2GB PST file size limit. This limit is caused by the ANSI format, which was used in older Outlook versions. In this article, we will tell you how you can solve this by upgrading to Unicode PST. I recently upgraded my old Outlook PST file from ANSI to Unicode with the help of Softaken PST Upgrade Software. This removed my 2GB limit, and the file got bigger without any problem. The tool is user-friendly and can be used easily, even without technical expertise. If you are also troubled by Outlook's PST limit, then try this software.

With its user-friendly interface and support for all Outlook versions, it’s the safest way to overcome size limitations.
