I recently purchased a new desktop computer and installed office 365. After setting my email in the outlook desktop app I found that I cannot send email from outlook. I have been getting a 0x80040115 error. I have tried the following:
Factory reset of new computer
Repair of office - both ways
Updated windows 11
Deleted and re added email accounts (this actually helps initially but after a few days it stops working)
Disabled virus software and firewall
Restarted many times
Reduced size of mailbox
Deleted app data (again helps for short time)
This will also effect corporate email after several days. I have no issues sending email from same account from my phone, laptop, or web mail.
I'd appreciate any thoughts,
Paul

Hello Pahat,
The Outlook error 0x80040115 occurs when a user tries to send an email, but the Outlook application fails to synchronize the changes to the mailbox server.
The error 0x80040115 specifies that your Outlook is unable to connect to the server. However, below given are the most common reason for this error occurrence.
If you are facing the above Outlook error, you can follow the following methods to fix the issue.
Flush DNS Cache:
Flushing the DNS cache will clear your DNS cache, as the issue might be due to DNS configuration.
ipconfig /flushdns
Disable Add-Ins:
Third-party add-ins installed in Outlook can cause an issue with sending or receiving emails. You can try to launch Outlook in safe mode to see if that fixes the issue,
Outlook /safe
Repair corrupt OST file:
Outlook stores a local copy of your emails in an OST file. When an OST file gets corrupted, you won't be able to receive or send any new emails.
C:\Program Files\Microsoft Office\root\Officexx
This tool will scan the OST file for errors. If it finds an issue with your OST file, you will get the option to repair it.
Thus, I hope the methods above can help you fix the Outlook 0x80040115 error and can send emails from Outlook.
