Trying to send emails to onenote has become frustrating. Once app button is selected, it throws a windows "something went wrong" window 0x80049dd3. Once I cancel that screen, it throws another errors screen "something went wrong (7q6ca). Once i close out that screen, the "send to OneNote side screen appears with a sign in button. Once I select that button I am able to sigh into my onenote account. However, I now cannot save anything and the same error messages appear.
Search the interwebs with no solution. Please help!
Moved from <Microsoft 365 and Office | OneNote | For home | Windows>
I tried everyone of the above solutions and nothing worked. I even unloaded MS 365 and reinstalled it to no avail. Finally, I reverted back to the original outlook and it worked well. It seems there is a bug in the new 2026 outlook autho with OneNote. I see when searching that several others have had a similar issue. Are there any other solutions? This is the only way I like to work with OneNote.

Hi Tom Pennavaria,
Thank you for your response and apologize for the inconveniences that you are experiencing. In practice, authentication incidents in New Outlook may take some time to fully stabilize. If the problem continues after trying the steps above, using Outlook on the web or switching to Classic Outlook may be a more stable temporary workaround.
Hi Tom Pennavaria,
Thank you for reaching out to Microsoft Q&A forum.
In New Outlook for Windows (Microsoft 365 / Outlook 2026), incidents affecting the Send to OneNote feature (such as 0x80049dd3 or 7q6ca) are typically related to Office authentication or sign‑in cache behavior.
Please try the following steps:
1. If the 0x80049dd3 incident appears, select Cancel (do not choose Continue) to dismiss the sign‑in prompt, then retry the Send to OneNote action.
2. Repair Microsoft 365 from Windows
3. Check for add‑in conflicts:
outlook.exe /safe4. Create a new Outlook profile:
Please feel free to let me know if you have any further updates, thank you.
