How to maintain document compatibility between LibreOffice and other office suites?

It is almost impossible to have 100% compatibility, however, if you are not using wordart/libreoffice draw features, etc, you can get high levels of compatibility by using a few simple things:

• Save your documents in a format that all the listed office suites can use (MS Office 2003 documents are best for this purpose, and more so with Word Processing documents).
• Only use features that are shared between the applications, so for example, use simple formatting in tables (by simple, I mean, just create a standard table, XY dimensions, without adding excel features etc, which can become complicated*).
• Use fonts that are available in all the suites. Missing fonts can produce problems.
• Use the program options to your advantage :)! I do not have office installed, but I do have LibreOffice. So for example, you can set up the Load/Save options as such: You can access this dialog by clicking tools>options in the menu.

Personally, I have found that using the .doc file format in LibreOffice improves compatibility with MS office.

Also, install the newest service pack for Office 2007 because it will add .odt file format support to Office. Odt is the default format of LibreOffice and OpenOffice.

I also know that using 1.5 line spacing sometimes lead to compatibility issues between Libreoffice and MS.

For Writer, go to options->LibreOffice Writer->compatibility and select the "do not add leading space (extra space) between lines of text" and the "consider wrapping style when positioning objects."

Lastly, LibreOffice has much better support for MS office file formats than OpenOffice.

One format almost 100% compatible between Ms Office and opensource applications is RTF. One issue is the files get bigger usually.
