Yes. If you have a large amount of mail or many big attachments, the target file receiving your messages can grow very big.
Outlook 2003 and 2007 can store up to 20 GB of data in a single file using the Unicode PST format, and Outlook 2010 up to 50 GB. Older versions of Microsoft Outlook create ANSI PST files that are limited to 2 GB in size. Note that the PST size limit may be set smaller through registry settings (see this Microsoft Knowledge Base). Some email clients cannot read generic mailbox files that are bigger than 4 GB. An Aid4Mail ZIP archive can easily exceed a size of 20 GB; in fact the maximum file size is limited only by your system’s resources.
In order to be sure, please check with the email provider you are migrating to, in order to ensure your file will not be too large to transfer. If your email provider does have a file size limit, you can set a threshold value in the "Limit File Size" field on the "Target Settings" screen.
