Depending on the organization we work for or to our personal preferences we use different email applications. Outlook for Mac, MS Outlook and Lotus Notes are mainly used email applications. They store files in different formats and we need to convert these files if switch from one to another.
We have discussed converting NSF to PST and OLM to PST manually. If we are shifting from MS outlook to Lotus Notes we need to convert PST files to NSF. Outlook to Lotus Notes can be converted by using a simple tool nUpgrade.exe. This tool converts PST to NSF format in easy steps.
