Are there any common problems when converting EMLX to PST, and how can I fix them?
Yes, you can face some common problems when converting EMLX to PST. The first one is the conversion tool does not recognize all the EMLX files when they are corrupted. If you want to fix it. Then you can use a reliable tool like the Dailysoft EMLX converter tool. They can handle most file types. And second one is attachments do not convert properly if the files are too long. If there is an issue with the tool. If sometimes the converted PST file is very large or corrupted then you can use this tool. And convert in smaller batches with an eye on the file size.

Many other third-party tools are available in the web market, but only a few are reliable. Here I am introducing one such tool I have used earlier, MacSonik EMLX Converter for Mac. The software is capable of removing duplicate emails while the migration is going on. It gives you an amazing Date-filtering feature that helps users migrate EMLX files from a specific date range. The tool is easy to use because of its simple user interface. It does not require any technical expertise to run this tool.
