Are there file size limits that need to be taken into account when exporting mail?
A. Yes. If you have a large amount of mail or many big attachments, the target file receiving your messages can grow very big. Outlook 2003/2007 can store up to 20 GB of data in a single file using the Unicode PST format. Older versions of MS Outlook create ANSI PST files that are limited to 2 GB in size (note that Aid4Mail cannot detect when this size limit is reached). Many email clients cannot read generic mailbox files that are bigger than 4 GB. A ZIP archive can reach a size of 4 GB, which in most cases it should be enough to store the contents of a 20 GB Unicode PST file (Outlook 2003 and 2007).

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 Aid4Mail cannot detect when this size limit is reached). 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.
