Hi, Facing issue in office 365. Suppose one excel file is already opened and if we tried to open another one it just is looks like opening file and if check after sometime it shows excel blank window to open new file.

Please help

Hi,

Thanks for your post.

Based on my experience, if you've ticked the option of "Ignore other applications that use Dynamic Data Exchange (DDE) under FILE>Options>Advanced, you will probably have this kind of issue.

Please try to turn off that option and see if it works.
