A family of Microsoft word processing software products for creating web, email, and print documents.
Hi ICOH,
Thank you for reaching out.
Since the document becomes read-only while you are actively editing, this may indicate document corruption, an interfering Word add-in, or a problem with the Microsoft 365 installation.
To resolve the issue, please try the following steps in order:
- Check Word’s editing restrictions
Open the document and check the following:
- Select File > Info > Protect Document.
- If Always Open Read-Only is highlighted, select it to turn the setting off.
- Go to Review > Protect > Restrict Editing.
- If protection is active, select Stop Protection.
- If the upper-right corner of Word displays Viewing or Reviewing, change it to Editing.
- Repair the document
- Open Microsoft Word without opening the affected document.
- Go to File > Open > Browse.
- Select the affected document once.
- Select the arrow next to Open, then choose Open and Repair.
- After the document opens, save it with a new name and test whether the issue continues.
- Test Word in Safe Mode
- Close all open Word windows.
- Press Windows key + R.
- Enter winword /safe, then select OK.
- Open the affected document and try editing it.
If the document works normally in Safe Mode, an add-in may be causing the issue.
- Go to File > Options > Add-ins, select COM Add-ins next to Manage, and select Go.
- Disable the add-ins temporarily, restart Word normally, and test the document again.
- Repair Office
- Close all Office applications (Word, PowerPoint, Excel, Outlook, etc.).
- Open Windows Settings (press Windows + I).
- Go to Apps > Installed apps.
- Find Microsoft 365 / Microsoft Office in the list.
- Select the three dots (…) next to it and choose Modify.
- If prompted by User Account Control, select Yes.
- Choose Online Repair > then select Repair.
- Follow the on‑screen instructions until it completes.
I hope your issue gets resolved soon. Any updates would be greatly appreciated.
