My problem is too complex for a simple one-line question. Is there an upload facility where I can describe the problem in some detail?

It must be how you are recieving these files and or how the writers are naming them.

First thing to try is to go to the Web Based Email system you are using and see if you can download, SAVE, those Word Doc attachments to your hard drive and then see if they open. If they do then it is the Email Client, Program, you are using that is somehow changing the format of those attached Word Docs. If that is Apple Mac Mail I suggest you find some other Mail client. Like Outlook that is included ion Office for Mac.

Rembrandt,

Did the two updates to Office 2011 get you to 14.3.9? That's the latest Mac version of Office.

I use Office 2013 and Mac Office 2011 on the same machine and have no problems opening any files shared between the two. You followed the instructions for uninstalling and updated your new installation correctly, I have to assume. It sounds as if there is a problem with your cuurent configuration but if it's not an update problem, or an installation problem, I can only direct you to the MS Office for Mac user community -> http://answers.microsoft.com/en-us/mac (sometimes you get lucky and get an actual MS employee answering your question).

Good luck,

Clinton

I am sorry I have no other suggestion.

You might be better off posting this over in the MS support forums specifically one that deals with MS Word for Mac 2011.

All my best to you.

Are dates present in the filenames, and if so, what format are they in?

Post one of the affected filenames, verbatim, inc extension.

This question is also on the iMac forum and no one has an answer. I called Apple Joint Venture and they told me to call Microsoft. I called them, and they told me the problem was my "virtual drive". They advised me to call Apple and ask them to turn off my virtual drive. So I plan to do that. I will report what happens.

I have the same problem and it started yesterday. I am an Apple Joint Venture member. They told me that Office products were never able to be shared between Macs. I believe that is incorrect. They suggested I call Microsoft. So I did. Microsoft remoted into my machine and told me the problem is with Apple Virtual drive. They suggested I call Apple and ask them to remove my virtual drive. I have an appt with Joint Venture later today. I will report what they say and if this works.

As the OP has not answered questions that would affect the finding of an answer what do you want us to do?

You have a different issue, why don't you start your own post, that way you can get your own attention.

I took your advice and started my own question - however my problem seems to be very similar to rklopper. I get the same error when I open an Office file on a different Mac from my Mac. I don't know if rklopper is networked or not, or how he's receiving the files that he edits.

My solution was to turn off file sharing using AFP, reboot, then turn on file sharing. That eliminated the Office message that rklopper has. Hope this helps.

Also have exactly the same issue, same error message. Interestingly the back-up copy from Word is not similarly affected. Using Dropbox to save these files (for ease of sharing between machines!).

Any help?

Your problem may not be exactly the same as that of the original poster of this older thread, and it can be very confusing for everybody if we try to answer more than one question in each thread.

In order for us to give your problem our undivided attention to try to solve it, would you kindly start your own thread, describing the trouble you are having in the fullest detail, including completing your details to show what Mac or iDevice you are using, what operating system, and what version of the application in question. Please remember to post in the forum relevant to your hardware or version of OS X.
