An outlook error found in custom UI XML is a quite frequent problem. It happens when you are using the outlook application. And outlook error is caused by some corrupted files. Other reasons might be related to a corrupted registry.
Or, sometimes, outlook error is caused due to some virus attack. A corrupted registry can slow down your system and cause it to crash frequently. These errors can be scary and annoying. However, most of them can be fixed easily.
Microsoft Outlook users’ graph in the bullish mode in corporate and personal use, due to several benefits. Sometimes, there can be some issues while working on Outlook. Recently I encountered Error 0x80004005.
This error code occurs when you click to generate a new mail. The error message may be displayed in the formats.

Outlook error 0x80004005 appears due to the addin you installed in your outlook (it’s true I personally use kutools, Grammarly, etc), the day I install them I am getting an outlook invalid XML error message.
The error found in custom UI XML is almost similar, if you click OK you will get 9-11 similar popups, the only difference is ID: mso.
After clicking OK for all these messages Outlook works normally.
How do I fix error 0x80004005 in Outlook?
You must disable all your “addin” available in Outlook and enable those you need until you will get back the error.
Another option is resetting your ribbon.
Here is the step-by-step guide:
- Step 1 – Open Outlook
- Step 2 – Click File >> Options >> customized ribbon
- Finally restart Outlook.
It works for me hope these steps also help you out and you will get rid of these issues.
Final Words
In conclusion, in the worst case, this could happen when the latest version of the Outlook desktop client is installed on the server. The error message will pop up in the Office 365 administrator center and should include the version number of the Outlook client.
