How to stop Microsoft Word from opening file in readonly mode

Solution 1:

1. Run the Office 2010 application with the problem. Notice that this procedure has to be done individually with each of the applications in MS Office suite (great!).
2. Click on the Office button on the upper left-hand corner and select “Options”
3. In the “Options” dialogue box, select “Trust Center” (on the left)
4. Click on “Trust Center Settings” (on the right)
5. Select “Protected View”
6. Disable any of all the protected view options by unticking the check boxes.
7. Click OK when done.

P.S. Do you have write permissions?

Solution 2:

Go into Word Options there's a check box under Start up options: Open e-mail attachments and other uneditable files in reading view. Uncheck the box and click OK. This should remove the readonly.
