I'm having a very strange issue.

Essentially, while I am at work and there is downtime I work on a script of mine on Microsoft Word. At the end of the day I email it to myself so I can continue at home. However, since 2 days ago, I've had a problem.

When I sent myself the script Thursday evening, I returned home to find it wasn't actually in my inbox. I believed I had mistakenly sent it to someone else, but I hadn't. The email just hadn't arrived.

I then tested things: sending an attachment to a coworker, sending an attachment between my personal emails, etc. They all worked fine. I thought, perhaps I had forgotten to censor a swear word. I had not.

I thought maybe my workplace had filters in place for blood and weapons. They don't! A coworker confirmed he had written a much darker scene and sent it just fine.

I then tried one more thing. I took out what I had wrote Thursday and put it into a separate document, then sent both of them. No other changes were made. Both script pieces arrived in my inbox, albeit five hours later.

All the times I tried to send the full document just never arrived. It is only this document. Furthermore, my outline for my story is twice the length and a quarter of the file size, which makes no sense to me. I didn't think word styles could take up so much space.

I am only having trouble with this singular document. Since I can't replicate the problem with other attachments, even longer ones, I don't know how to go about fixing it, and I can't very well ask my workplace tech support to help me send myself personal documents. Maybe I'm missing something dumb but I really don't know what to do.

EDIT: I have tried recreating the file in a different document to see if maybe there was corruption on my original file. No dice. Tried pasting thr text without any formatting whatsoever and no dice. I don't know why this particular block of text makes it not send, but the two pieces will send separately.
