Helping people with computers... one answer at a time.

Office 2007 introduces a new XML based file format for its documents. There's a download for older versions off office to read and write the new format.

I have Microsoft Office 2003 on my computer. Friends of mine are sending me e-mail with attachments but are using Office 2007. Is there any way to convert Office 2003 to open e-mails from Office 2007?

Office 2007 introduces a new file format which is, of course, incompatible with previous versions of Microsoft office. So if you receive a document that someone has saved in Office 2007 format, but all you have is an earlier version of Office that can't read it, there are some steps you need to take.

But I also need to nit-pick one part of your question as well.

You asked "Is there any way to convert Office 2003 to open e-mails from Office 2007?" Emails should open just fine. Email messages are sent and received in a format common to all mail programs, and no conversion should be necessary.

You should also be able to save any attached documents. Again, attachments themselves are encoded into email in a standard way that has not changed. It's the format of the attached files themselves that has changed, and the program that's used to open the attached files needs to be able to handle their new file format.

You could, of course, ask your friends to save their files in the older format. This isn't the first time Office has changed formats, Microsoft Office has a fine track record of being able to save in older formats each time they change to new ones. Your friend could save his file in Office 2003 format before he sends it to you and you'd be able to read it like nothing changed.

What's unique this time is that Microsoft has made converters available for older versions of Office.

Download and install the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. (Take special care to read the Overview on that page - it's important that you have all High Priority updates from Microsoft Update installed before you install the converters.)

The compatibility pack works with Office 2000, Office XP and Office 2003.

It seems as if Microsoft is trying to push Office 2007 by excluding people without an old version of Office from viewing files in the new format.

Up till now, Microsoft has offered free Viewer programs for the office applications which let people with Open Office, Works, the Corel suite or whatever, view files created in Office. There doesn't seem to be a viewer program for Word 2007 or for Excel 2007 (there is one for PowerPoint 2007). I wonder why.

The advantage of a stand-alone viewer program is that it is less intrusive than updating an older version of Office and less likely to cause a problem (always a possibility with any patch/update). Then again, it is a viewer, not an updater.

Dear Leo,

My notebook is on Win Vista with MS Office 2003. Recently I have been received mails with attachments of office documents(Word or Excel without the usual extensions ie .doc or .xls) which I can only opened when I clicked on it and tried wither to "open with" either excel or word.

I have downloaded and installed both OCONVPCK file , File Format Converters as well as Compatibility Files.

Unfortunately, the problem persists. It will not auto convert files whereby I can open straight away as it is.

Pls help! Thanks.

see if you can install this update for office. It should allow you
to view docx files and convert them to regular doc files.

The update is here:

i am having set of xlsx and pptx files, need to convert those to xls and ppt. but the command line is not doing any help.

I have downloaded the office compatibility pack and installed, then i tried for the xlsx to xls conversion

c:\Program Files\Microsoft Office\Office12>excelcnv -oice c:\xl.xlsx c:\xl.xls

it gives out a xl.xls but its just the copy of my input xlsx file when i open that file in the office 2000 it gives error. i just renamed the xl.xls to xl.zip, now i can see the xmls inside. so it just created the copy of my input file and renamed it to xl.xls.

Any help on this highly appreciated.

Thanks

Article says pack only works as far back as Office 2000. I still use Office 97, and it's really all I need so I don't want to upgrade. Is there a compatibility pack available to work with Word 97?

Not that I'm aware of. After 12 years it might be time to upgrade.

Hi Leo, they switched my M Office from 2003 to 2007, I now use MS Off 2007 excel, it has a pale blue format all over the place how can i change this new "screen-template" etc to the older 2003 version, which was much simpler in appearance and easier on the eyes. any help in changing the appearance to the older version is helpful.

(just in case i'm confusing, i like the older version of "classic windows" screen (etc) to the new(er Win XP screen.

thanks !

I'm not aware of a way to get what you're looking for in Office. The visual layout was a pretty major change, and I don't believe they included a way to revert of "look something like it used to".

I install the Compatibility package for Office 2003 on my Windows 7 system a couple of months ago. Since that time NO Windows updates from MS for office have successfully installed. There is no mention of this specific problem on MS sites. The specific error code was 52F.

Your .xls files are probably corrupted.
