It sounds like the text box you are trying to rotate may be anchored to a specific location in your document, which can prevent it from being rotated. Here are some steps you can try to rotate the text box:

1. Click on the text box to select it.
2. Right-click on the text box and select "Format Text Box" from the menu.
3. In the "Format Text Box" dialog box, click on the "Layout" tab.
4. Under "Wrapping style," select "In line with text."
5. Click "OK" to close the dialog box.
6. Click on the text box again to select it.
7. Click and drag the green rotation handle at the top of the text box to rotate it to the desired angle.

If the rotation handle is still grayed out, try selecting the text box and pressing the "Ctrl" key while clicking and dragging the rotation handle. This can sometimes override any anchoring or other formatting that may be preventing the text box from being rotated.
