Excel Data Lost after Emailing File

Hi everyone,

I'm wondering if someone can assist or give insights to a really annoying problem I'm facing. My wedding guest list loses some of its data after the file is emailed. It's unbelievable because it's saved over, and over, and over.... you get the idea. I'm extremely paranoid about this stuff so I'll save it after every little change I make, close the document, and reopen it JUST to make sure that it was actually saved. I've always been this way and never had this issue until recently.

I first noticed this with a less important Excel document. I saved the file obsessively as usual, double-checked the info was all still current, saved AGAIN, then emailed it to myself for use on a different computer. I download the SAME FILE onto a new computer, open it, and magically, a LOT of information is missing from the document. That was the first and only other time it's happened.

So of course now, it's happening with my wedding guest list. It's not because I didn't save, either - as I said, I saved MANY times and double-checked. I didn't have multiple versions and email the wrong one, I didn't save it in the wrong spot and send an old recovered version, etc. Just like any other old document, I saved it, and sent it. There should be no reason for this to happen, but clearly something is going on.

Any ideas?

Thank you!

Either EXCEL became corrupt and needs to be reloaded onto your computer or ... there is something in your macro code causing the issue (if you are using code).

Have you had a recent WINDOWS update ? Oftentime the updates cause corruption.
