Windows 10: How to stop OneDrive from trying to back up huge Outlook .pst files?

Hi,I have started using OneDrive for backing up my PC and making my files available on my other devices, such as my phone. The problem I'm running into is that OneDrive is backing up my Documents folder, and I have two huge Outlook .pst files in a folder under Documents the folder is \Documents\Outlook Files. I don't want OneDrive to back these files up; they are enormous, and it's all stored on a mail server anyway so I don't need them backed up again. How can I get OneDrive to not back these files up? I thought of creating a new folder under This PC and moving them there, but I don't think

Outlook PST File Problem

That is exactly what I was going to suggest. Export everything to another PST file, delete the old(or rather move it out of the default folder) and replace it with the new PST file that you exported.

 

Outlook PST File Problem

Thanks again everyone. I just did an export on the troubled PST file to create a new PST file from it and the file size went from 3.9GB down to 850MB. Then I installed the new PST file into Outlook that I just created and removed the old PST file from Outlook and all seems to be working fine so far. I think I am good now, but I will give it some time just to make sure there are no problems before I delete the old file. Thanks again.

 

Outlook PST File Problem

Outlook .PST files are maxed at 2GB's anything over that and they become corrupted. You can try the scanpst.exe from above. Also this might help you.
