OneDrive changing the dates on my photos?!?!?

45,000 photos!?!  That breaks my heart.  Some time ago I complained about the same problem. No response.  I need to be able to find files based on modified date.  I also need to know when was the last time a file was actually modified.  Sometimes I think that some of these companies are too big for their britches. (I just deleted almost a paragraph of related complaints)   I haven't decided what I'm going to do with my 30 years of business records but I need to move them to a remote location that won't mess with the modified dates.  I am so sorry about all this complaining.  I just feel so powerless.

Hello,

I recently uploaded 45,000 of our family photos to OneDrive, the dates ranging from 1999 to 2018.  They had been previously separated in folders by year and month, so decided it was time to back them up in the cloud and take advantage of Microsoft's photo features through OneDrive.  After uploading all of my photos, I was shocked to see that many of my photos were reorganized.  Randomly, photos from 2002, 2005, 2009, 2014, and 2016 were shown as brand new photos with a current date stamp.  I found that there were literally hundreds of photos that were RE-DATED to the the date that I uploaded the photos.  Somehow, OneDrive physically changed the metadata on the Date Modified and Date Taken to reflect the date that I uploaded the photos, not the date that they were originally taken.  Even worse, the uploaded picture permanently changed the date on my local pictures, so now these photos are irreversibly corrupted and I cannot organize them by date anymore.

Microsoft, this is a massively humongous bug in the OneDrive system that I found, by searching, has been questioned several times before.  Whenever I look at those posts, the commenting has been locked so that nobody can comment anymore.  Not sure why Microsoft wants this issue hushed by the community, but this problem will not just go away.  It needs to be fixed as soon as possible!!  We have thousands of photos that are unknowingly being corrupted, most people probably just haven't figured it out yet.

One potential solution to this problem would be to turn off whatever mechanism is redating photos/videos, or changing metadata.  If anyone else is having this issue, please comment below.  Microsoft, is there anything being done to fix this bug???

Thank you, and I respectfully appreciate your attention to this matter.  OneDrive is a great service and I really hope to continue using it.  This is just too big not to make top priority in resolving.

We have the same problem above.

Dates taken cannot be changed and are often wrong

Most of the photos are unorganized and i have posted this before.  Microsoft must not care?

As indicated in an earlier post, the File Explorer | Properties | Details allows the date portion of "Date Taken" field to be edited.  But the Time portion of this EXIF field cannot be edited in File Explorer.  If you shoot 100 images in one day, you lose your ability to control or alter the sequence with the time of each image.  If you have many thousands of photo files, it may be impractical to edit the Date Taken on each one.  

I know I need help to perfect my workflow, but here is a start:  (1) Import from SD card with Multi Commander (or equivalent) with the setting to preserve all EXIF dates/times.  I personally prefer to focus on one folder for each month/year.  (2) Screen all photos and their dates.  (3) Move unusable photos to a Trash folder (review it later), and note those files that need date correction.  (3) Make a backup of these usable photos.  If you mess up the following steps, you don't have to go back and begin again.  (4) Use bulk file correction software such as EXIF Date Changer Pro (Rellik Software) or File Date Corrector (Infonautics GMBH) to fix the dates that need correction.  (5) Use Advanced Renamer to rename all files to include the date and time and possibly the location derived from GPS data.  Advanced Renamer lets you format date/time as you like, and it adds location names to go with the GPS coordinates.  Now when I see an old file named "2017.07.04  11.35.12  Napili-Honokowai," I know it's one of our favorite small resorts in Maui, and I know I have followed the workflow to make the dates reliable.

With old photo files and scanned photos, there is a need to fix or add dates and GPS one by one on all photo files.  You can use Picasa or Geosetter or equivalent to add GPS map coordinates.
