I am new to microsoft Office. I purchased Office 365 to work on some files that were sent to me, because I couldn't view them on line. I could view them on my iphone, but there were numbers that were colored blue in the document that supposedly were to be editable. That doesn't work on the iphone. I let the repair screen run all night, and nothing worked. An older version of the file did work, but I deleted it. Now the new file which was sent separately to me will not open. I've tried manual mode. That doesn't work. Help!
