CRM 2011 Rollup 12 – Script Error 800a139e

This issue has been driving me crazy. It started the very moment that we applied CRM 2011 Rollup 12 to our development environment.

While working on a new CRM for a customer, I had a scenario where a Virtual Box Windows 7 operating system was generating a script error on just about EVERY mouse click on the site navigator, yet on my host Windows 7 operating system, no errors were being generated. Other team members were also not encountering anywhere near the volume of errors I was seeing?

Familiar Script Error Dialogue:

Error Detail:

“Could not complete the operation due to error 800a139e.“

I tried all the usual things like emptying IE temporary files, IE compatibility mode and other IE versions. No difference.

After sending hundreds of error reports to Microsoft :-), I searched for hints as to what could be causing this strange behaviour?

The solution is very easy to apply, but unfortunately looks like a bug as you have to disable a great feature in CRM – IM Presence.

The reason? If your operating system does not have Lync or other IM software present (Lync is the only one I tested anyway) the customer record grids fail to load correctly and the error is generated (often).

Turn off the IM Presence feature and your browser will operate fine, no errors.
