Saving PDF files to OneDrive

I have the same issue.

Tried rerunning OneDrive - does not help

Tried signing out and signing back in to OneDrive - does not help

Tried turning iPad off and on again - does not help

Tried deleting and reinstalling OneDrive - does not help

Did a full erase of my iPad and manually reinstalled only the OneDrive App (in case another app was creating the Helper App conflict) - does not work

If someone has a solution to this problem please let me know. It affects both iPad and iPhone.

I think Apple messed something up in IOS15

Unfortunately this didn’t work for me.

The issue is not that I can’t access files stored in OneDrive (which I can). The issue is that when I try to save a file to OneDrive it says “The Operation Can’t Be Completed. Couldn’t communicate with a helper application”.

This is the case whether I

• open an email attachment and try “Save to Files”
• try and do a “copy” or “move” of a file within the Files application - e.g. move a file from iCloud to OneDrive

However, if I open something in Microsoft Word, PowerPoint or Excel, then I can save the file to OneDrive.

Useful information. However, I have the OneDrive App installed - and can access files stored in OneDrive using both the OneDrive App and native Files App without issue.

As a further suggestion, try removing OneDrive from the Files App. From the Files sidebar, tap the ellipsis icon (the three dots “…” at top-right of the sidebar) to trigger the associated Action Menu; select Edit Sidebar. Next, disable Onedrive - then tap Done.

Force-restart your iPad - then re-enable the OneDrive integration in the Sidebar.

Same problem here. This solution did not for me ether. I am looking all over internet but no solution yet. I am trying to save single PDF files that I create in excel on my iPad Pro 2 th gen. No communication with helperapp error.

The “helper” App is the OneDrive App. In all likelihood, you will simply need to run the OneDrive App - and re-authenticate your Microsoft credentials.

OneDrive has just been updated - with fixes for issues that affect some users.
