Word cannot complete the save due to a file permission error when resaving Word document.

Question

So I have to rename it to be able to save the document. This happnes once in a while. What's the reason? And what should be done? (From "Word" to "error" is the error message in the title)

Hi,
What Office version are you using?
Please try to start Microsoft Word in Safe Mode if it helps, following steps for Word 2010, the steps for Word 2007 are similar:
Click Start, point to All Programs, and then point to
Microsoft Office.
Press and hold the CTRL key, and then click the Microsoft Word 2010.
If the problem does not occur in the safe mode, this issue might be related to some third-party add-ins in the Office program, we can try to disable them. Normally, you could do the following to disable the conflict add-ins in your Word program:
Click File menu, click Options > 
Add-ins, click Go button in the Manage: COM Add-ins.
Check if there has any add-ins, clear the checkbox to disable them.
Close the Microsoft Word and restart it.
Add one check back each time to the list of Add-In, restart Microsoft Word, and repeat the above procedure. Once the issue reappears again, we can determine which add-in causes this problem and then disable it.
- You may also check Save Folder and Word Default Save Folder permission, make sure user account has Full Control and Modify permission.
Best regards.
