So you would bounce .zip files for being too large if/when uncompressed? This seems to go against why people commonly compress email attachments. -- ME2 On Wed, Oct 20, 2010 at 7:40 AM, Cameron <cameron.orl...@gmail.com> wrote: Good morning all! More an informational post than anything. Was it just me that didn't know that the new MS Office documents (.xlsx, .docx, etc) were compressed files? Vipre for Exchange was trapping an 8mb .xlsx file even though the limit was set to 50mb and saying that it was over the size when uncompressed. So...Sunbelt Tech Support (which in my opinion rocks!) helped me to determine that the actual file size was 54mbs..therefore being bounced. Who'd a thunk it.
