Error loading control

Posted on by kjjb1013b

About 10% of our Customer Service team are getting the "error loading control" message when trying to view Contacts, forward emails, or view email attachments. Zero consistencies with roles/permissions/teams. Changing browser, clearing browser cache, restarting devices, doesn't appear to affect this. No changes made by our team to the solutions, permissions, etc. Switching between old Dynamics and the new look doesn't appear to make any difference.

I have raised a ticket with Microsoft, but wonder if anyone else has had this recently?

Full error message:

An error occurred. Please try again or contact your system administrator if error persists. An error occurred.

Hello kjjb1013b,

Please check the network latency once as per the MS article Verify network capacity and throughput for clients - Power Platform | Microsoft Learn

Also, please confirm if the remaining 90% of users can access the system as expected.

Switch the network or use the system where the other user is working as expected.

Even, you can opt for 30 days trial and check if that system works for you.

All this will help you to drill down the issue.

Hi @kjjb1013b

We’ve been experiencing this issue intermittently as well. Unfortunately, we haven’t made any progress with Microsoft support, as they insisted on network traces, which seems impractical given our team’s size (30 plus users) and the sporadic nature of the problem. Capturing traces would likely require agents running them for several hours per shift or continuously until the issue occurs, at which point the volume of data would make it like finding a needle in a haystack. You mentioned raising a ticket - have you had a different experience?

I'm debugging a similar issue for one of our Ukranian consultants.
We are not sure it's a connectivity issue, I'd like to know more about this since it's verified
