Why Does Word for Mac Now Prompt Me to Save Changes Not Made?

Robert Burns 95

Why when I merely open in my Mac running Sequoia 15.6.1 and Word for Mac 16.103.3 am I told that I "Your changes will be lost if you don't save them"? And, how do I get Word to stop this farce? This problem seems to have a very recent onset. I want my files to indicate when I last edited them not when Word has tricked me into saving them without changes.

Before attempting to troubleshoot anything it would be advisable to update the operating system. Version 15.7.2 is the current release of Sequoia. That alone may resolve the issue.

Also note that there are a number of background actions [e.g., updating of fields] which aren't enacted by the user but do constitute changes in the file.

I am surprised to find out that there are 2 OS updates. I amd now updating to the higher Sequoia but not the Tacoma (or whatever it's called). I recall no notification of updates. Thank you!

I'm just curious... Did updating resolve the issue? If so or even if not, why did you mark Tammy's reply as the answer when all she did was refer you to my suggestion? I'm not a glory hound, I'm just trying to understand.

My question wasn't why mine wasn't marked. It was why that one was. I couldn't care less about the metrics & I'm not compensated in any way.

Fair enough, the OP could have left both Answers unmarked. I see what you mean. (Also, in a thread with few Answers, there are not many posts that can be Accepted, of course.)

I have also had recent onset of this issue; I get prompted for every single word doc I open, none have embedded urls, and I have the latest versions of Mac OS and Word. In fact, I think this started after the last update to one of them

Ditto. For the love of anything good, will somebody please offer an answer that does not repeat what has already been said, that in my experience does not work? Surely this is a Microsoft problem; it did not exist for me before their last update to my 356. It is extremely annoying to have to answer the pop-up every time a file is closed.

Did you report the problem to Microsoft using the Feedback facility in Word for Mac and/or via the portal at https://feedbackportal.microsoft.com/feedback/forum/fb6d67e3-301c-ec11-b6e7-0022481f8472 ?

For now, that is the best that can be done.

Forum contributors usually do not get information on how Microsoft developers prioritize bugs or possible bugs. It is known that bugs which cause data loss have high priority, though.

Thanks, Stefan. I've done as you suggest, and adjusted my expectations accordingly.

I am running Tahoe 26.2 and Word 16.106 and getting the same issue - even on a single page document. I just created a brand new document and typed a single word, saved it, then reopened it for 30 secs then closed it without doing anything at all, not even scrolling and got the 'save changes' prompt upon closing.

Dear Robert Burns

Welcome, and thank you for sharing your issue in the Q&A forum.

Based on the information you provided, I understand that you’re experiencing the situation where Word displays the message “Your changes will be lost if you don’t save them” even when you haven’t made any edits. I’m truly sorry to hear about this inconvenience.

However, I noticed that Bob Jones mentioned updating macOS to version 15.7.2. Have you tried that step yet? If so, did it resolve the issue for you? If the problem still persists or if you encounter any additional issues, please feel free to share them with us. We’re always ready to assist you.

Dear Robert Burns

I see you've initiated the OS update! Upgrading to the newer version of Sequoia is a proactive and crucial step, as these updates often contain compatibility fixes for the exact issues we've been observing.

Once the update is complete and your Mac has been restarted, please perform one quick test to help us pinpoint the solution:

Re-open one of the Word documents that previously triggered the "Your changes will be lost..." message.

Immediately close the document, without making any actual edits.

Could you please let me know the current result? (Is Word still prompting you to save?)

Your feedback will be essential in determining the precise next step to resolve this issue completely.

Yes, the same problem continues. There is yet another upgrade to macOS Tahoe 26.1 which I probably will install Friday night. BTW, I have even caught Word wanting to save itself after a file has been open awhile as if some auto-save function is at work hallucinating changes.

I updated to macOS Tahoe last night and the problem continues. I am unimpressed with this continuing, new software defect.

Dear Robert Burns

Thank you for your response, and I truly apologize for the late reply.

It appears we are indeed dealing with a persistent software defect inherent to this version of Word. Since this is a recurring issue that persists even after your OS update, reporting it directly is the best way to secure a fix in an upcoming patch. You can do this via Help > Feedback reports a Problem in Word or by visiting the Microsoft Feedback Portal. This sends your system logs directly to Microsoft engineers so they can investigate why this specific version is misbehaving.

For now, this is the most effective path toward a permanent solution. Thank you once again for your incredible patience and for sharing your insights.

I find no way under Help to do do so in Word. The portal doesn't tell me to do anything beyond what I've already done. M$ gives Mac users the indication of "tough it". Frankly, with the corporations $ it should monitor this site out of obligation and, if it really believes in AI (I don't) it should use AI to monitor it. My conclusion: Known defect.

I had the same issue and the 5 Microsoft support members were absolutely no help. hours and hours I spent with them. I reluctantly shared my screen with the third one. But I was desperate. The last one told me I needed to change my user profile!!! What a waste of time! I should've come to this forum first! They should've come to this forum! I disabled copilot and BAM!!! Done!

I have tried ALL the recommendations posted in this thread. They do not work. I have Microsoft 365, have updated Word to latest version consistently and the Mac OS as well. I have used WORD for 30 years without such a problem and then after an update about three months ago this pain the A started. NOTE: I have no option box to enable or disable Copilot in the Preferences or any where else. If I just open open a Word file, (doc/docx) look at it for a second or two, and then attempt to close it, I receive the prompt asking me if I want to save the changes I made otherwise I will loose them. Pain in the A, something that Microsoft has known about for ages, but yet I still continue to be charged for a subscription to a program that has a bothersome programming fault without a known fix. Dear Microsoft - FIX IT!

Go to Word's (not the OS's or Chrome's or whatever's) Preferences and then you should find the Copilot icon in the first position in the left in the 2nd row from the top, disable it and reboot Word if it is already open. If you actually have tried this approach, advise us of

how far you got and the result.

I do not have the Copilot icon option in my Word Preferences box. I just updated WORD two days ago to version 16.106 for Mac and have kept the program updated continuously. This icon has never shown up in the preferences box as the second line only has the East Asian Languages icon. This problem did not exist until approximately two or three updates ago.

I also have Word `16.106. My OS changed last night to Tahoe 26.3 but all appears unchanged as to co-pilot. So, the problem is over my lay head as to the source of your obvious software failure/conflict. Best wishes.

I found this at, for whatever it might be worth, at Google AI and you might try the reverse to see if you can restore the Copilor icon:

Remove Copilot from the Ribbon (Hide Icon)

Even with Copilot disabled, the button may remain on the toolbar. To remove it:

Go to Word > Preferences > Ribbon & Toolbar.

In the "Customize the Ribbon" section, select Home.

Locate the Assistance group (which contains the Copilot icon).

Click the left-pointing arrow (<) to remove it from the ribbon.

Click Save.

Same for me, OS Tahoe 26.3. I wonder if I need a complete uninstall and reinstall of the OS? The Copilot icon shows up on the WORD Ribbon, but it is not listed as a Ribbon option that I can remove

Thanks for the suggestion, however Ribbon and Toolbar is not an active option in my Word Preferences box under Authoring and Proofing Tools. The icon is in the background but I cannot click it to initiate any type of action. Really weird.

This is still an overdue inefficient farce nearly 3 months later that when we read a file without changing anything, we are forced to still save them. I'm running Mac Tahoe 26.3 and Word Version 16.107.2 on 2026-04-01.

I found the answer to this problem. I also tried all suggested solutions, which failed. I also could never find a Copilot icon that I had any control over.

My colleague informed me that my organization's licensing agreement prevented access to Copilot controls -- that my own organization imposed Copilot on everyone, and there's no way to change that. So imagine the answer is that this glitch is caused by an interaction between Copilot and Word files that are opened, even if not edited -- and those of us with company or institutional 365 software are just stuck with this annoyance. My colleague said that he switched to Pages long ago to avoid this kind of thing, and exports/imports from Word without any trouble.

I had the same problem, starting with Mac OS Sequia and continuing with Tahoe (26.2).

I checked and the setting “Automatically Update Document Styles” was already disabled. I also updated MS Word a few times, but the problem of getting asked to save every word file that I opened continued (a very annoying and counter-productive bug!)

I then turned off Co-pilot (Preferences -> Copilot-> deselect Enable) and the problem stopped! So I recommend everyone to try this first, as it seems to be causing the problem, at least in my case.

@Vasilikiotis Christos,

Recently, there have been several reports in Q&A stating that Word displays "excessive" save prompts, both for MacWord and WinWord. That is why sending an error report to Microsoft might be a good idea. Use the feedback facility in Word or the portal at https://feedbackportal.microsoft.com/feedback/forum/fb6d67e3-301c-ec11-b6e7-0022481f8472 .

That said, there are many actions which may make Word determine that a document has changed, even if no visible changes have been made. The list includes printing, saving to PDF, and updating fields.
