Office 365 disappeared then created a new inaccessible one drive
I turned on my computer last week and all my office 365 apps were gone for no apparent reason. I googled it and did a reinstall.
Today I realized that as I write in word or do sheets in excel, it's saving to a newly created one drive folder.
I'm a writer and I have a zillion files in the old one drive folder. My file explorer is attached to the old one drive folder. So when I tried to upload a document to an online portal, I couldn't because file explorer doesn't recognize the new one drive.
I don't want the new one drive, I want the old one where all my stuff is.
I tried working in word from one of my old documents but it won't autosave because it's looking for the new one drive but was saved in the old one drive.
How do I get my office 365 apps to sync with my original one drive account instead of the new mystery account? I'm nervous to try anything lest things disappear completely.
thanks
