Hi, I am switching over to Mac on Tuesday!! All my business emails are currently in Microsoft /outlook 2003 on my PC - I have read that you can download an import tool which is great. My worry is on the size of each .pst / .mbox file as they are around 2gb each. Will this cause stability issues within Entourage or OSX? Alternatively is there another strong email program for OSX? I like the calender function of Outlook however could live without it if it means having a stronger email client that can handle multiple folders (upwards of 100) and plenty of mail. Thanks for any light..
