Are there any file size or message count limits?
However, when processing extremely large email archives it may be helpful to increase the amount of memory that Emailchemy uses. This can be done by editing the vmoptions file.
On macOS, this file is called vmoptions.txt and is located inside the Emailchemy.app file; to see it, right-click on the Emailchemy.app file, select “Show package contents”. On Windows, this file is called Emailchemy.vmoptions and is located inside the Emailchemy install folder.
- Open the vmoptions file in a text editor of your choice
- Add this line: -Xmx2048m
- Save the vmoptions file then run Emailchemy and try the conversion again
If that’s not enough memory, change the line in the file to -Xmx4096m.
