Hello, you can try these steps below:
1) Check Default Save Format:
Open Microsoft Word.
Click on "File" in the top left corner.
Choose "Options" at the bottom of the left navigation pane.
In the Word Options dialog, go to the "Save" category.
Look for the "Save files in this format" or a similar option.
Ensure it is set to "Word Document (*.docx)" or the desired Word format.
2) Save As Option:
When saving a document, use the "Save As" option instead of just "Save."
In the Save As dialog, confirm that the selected format is "Word Document (*.docx)".
3) File Extension:
Ensure that the file extension of your document is ".docx" and not ".pdf" before saving.
If needed, manually type ".docx" at the end of the file name when saving.
4)Repair Microsoft Office:
If the issue persists, there may be a problem with your Microsoft Office installation. Try repairing Office:
Open "Control Panel" on your computer.
Go to "Programs" > "Programs and Features."
Find Microsoft Office in the list, right-click, and choose "Change."
Select the "Repair" option and follow the on-screen instructions.
5) Update Microsoft Office:
Ensure that you have the latest updates for Microsoft Office installed. Sometimes, issues are resolved in newer versions.
Open any Office application.
Click on "File" > "Account."
Click "Update Options" and choose "Update Now."
6)Check for Third-Party Add-ins:
Disable any third-party add-ins that might be affecting the Save functionality.
Open Word and go to "File" > "Options."
Select "Add-ins" on the left sidebar.
In the Manage box at the bottom, choose "COM Add-ins" and click "Go."
Uncheck any third-party add-ins and click "OK."
Check Group Policy Settings:
If your computer is part of a network domain, group policy settings may be affecting this behavior. Contact your IT administrator to check group policy settings related to Microsoft Office.
If none of these solutions resolve the issue, it's recommended to reach out to your IT support or Microsoft Support for further assistance, as there may be specific configurations or issues related to your environment that require more in-depth troubleshooting.
