M365 Backup - Backup of OneNote Items fails

Yep I recall, my point is that it’s a known issue so when Microsoft 365 7 P20230704 (7.0.0.3968) is re-released or from what I’m hearing Veeam might skip ahead beyond this version, the fix will be included 🙂 so there’s nothing else we can do until that update is available, other than see if Veeam support can issue a Microsoft 365 7 P20230704 (7.0.0.3968) + hotfix or a hotfix for 7.0.0.3604 P20230512 (aka the currently available latest release)

You're welcome be sure to mark an answer for your question once fixed.

Unfortunately updating to 7.0.0.4388 did not resolve the issue for us either🙁

We still have the same problem with version 7.0.0.4388 P20231015

We are experiencing the same problem. 7.0.0.4388 did not help.

I opened a case today.

Once you post in a thread you get updates automatically.  😉

we also are experiencing this… fix out soon i hope…

I opened a support ticket yes and for the moment response of support is a Microsoft issue or corrupted OneNote page … but we have several users with erreor when backing up about :

/personal/user@domain/Documents/User @ domain/OneNote_RecycleBin/OneNote_DeletedPages.one.

Download request retry timeout exceeded.

Case #06400649

Hello,
 
I did some testing on this scenario and I found a way to be able to verify if the files can be downloaded.
 
In the majority of the cases the file is corrupted so you can try to download it but in the last couple of weeks, Microsoft have done some changes to SPO and you can't download OneNote files  anymore, so you can to try to open and download the tabs using this method:
 

1.Navigate to the location where the OneNote is stored:
 
In the O365 Admin center click on Users -> Active usersFind and open the user for which the backup failsClick on OneDriveClick on "Create link to files"Open that link
 
2.In the same folder, create a new folder with this format: Name of the OneNote+2
 
You can just copy the name of the OneNote and add a 2 at the end. EG: "problemItem2"
 
3.Open that folder in the browser
 
4.Edit the path to the folder and remove the 2
 
OneNote file name is test and I created folder test 2.

This will open a tab and the OneNote will be displayed like a document library and not a file, in there you can see the OneNote tabs and other OneNote additional files, in that list you need to find the file called %%%%%%%%%% and try to download it.
 
Those items are downloadable:

After that, please download the file from there and remove it. Reupload the file after that to the same location and start the backup job again.
 
If this fails with the same message, please consider moving the file to another location or add the file to a .rar archive.
 
============================================
 
If the files can't be downloaded this means that the problem is with the source.
 
In this situation, please raise a ticket with Microsoft in regards with this behavior and present them with the results from our previous tests.
 
Another workaround will be to copy each OneNote page to a new section and delete the corrupt one afterwards. After that the download button will work again and the backup will work.

Thank you @DSI Astreinte for sharing! After replacing the corrupted .one-Files our issues were gone.
