OOXML Strict is supported only by MS Office 2013, while all other MS Office incarnations will not open it (and will tell the user that the file is corrupted).
This statement is not accurate. ISO/IEC 29500 Strict can be opened / edited by MSO 2010 and opened / edited / saved by MSO 2013 and MSO 365. This was blogged about back in 2012 (where "New Office" implies MSO 2013 and MSO 365): http://blogs.office.com/2012/08/13/new-file-format-options-in-the-new-office/ The *default* file format used by both MSO 2013 and MSO 365 is ISO/IEC 29500 Transitional. This can be changed to ISO/IEC 29500 Strict if necessary: http://social.technet.microsoft.com/Forums/en-US/e969fc0a-9fcd-4efe-bf6d-79ea8c34360f/what-is-the-default-file-format-for-saving-in-ms-office-2013-is-it-still-the-transitional-ooxml-or?forum=officeitpro ----- Best wishes, Owen. -- View this message in context: http://nabble.documentfoundation.org/What-version-tp4118061p4118374.html Sent from the Users mailing list archive at Nabble.com. -- To unsubscribe e-mail to: users+unsubscribe@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
