Hi,
I've been running Exchange 2019 for 6 months with no issues, but since the beginning of the week I have noticed that when I access ECP via my browser I receive the following error:
"error - Your request couldn't be completed. Please try again in a few moments"
The ECP opens up on the recipients/mailboxes area by default and the mailbox highlighted generates the error. Clicking OK only just generates the error again.
Upon further investigation, I have found that this effects the following browsers - Edge (my default), Chrome and Firefox.
The ECP is only useable via Internet Explorer
The URL I use to access ECP is:
https://mail.company.com/ecp/?ExchClientVer=15.2
There have been no updates installed on any of the Exchange servers since the last CU ( Exchange CU9) and round of server 2019 updates were installed a couple of months ago.
All Exchange servers have been restarted and the issue persists.
The below error is generated on any of the servers when accessing ECP:
Anyone experiencing the same behaviour or have seen this before?
Thanks in advance

Thanks for the detailed information!
Sorry I still need to ask a few more questions:
In addition, have you tried with another admin account?
Hi,
There are four servers, all CU9 and patched to the same level.
The ECP is accessible without issue locally on each server, via the only browser which is installed on server 2019 - which is of course IE
I have installed Chrome on another non-Exchange related Windows Server 2019 server and accessed the ECP - no issues or error messages.
OWA works fine via any browser, via Windows 10 or Server 2019
EMS works fine via Windows 10 or Server 2019
I have tried another admin account and the results are the same.
This would lead me to think that there is a Windows 10 specific browser incompatibility issue with Exchange 2019, as I have the same issue on multiple Windows 10 machines.
Hi,
Thanks for the update!
I tested in my lab (Windows 10 with Chrome, Edge and two Exchange 2019 CU9 in a DAG ) but was not able to reproduce the issue.
Does it happen on a certain version of Windows 10?
And just in case, do you have some add-ins in the browsers?
I am writing here to confirm with you how thing going now?
Did the issue get resolved?
Hi, Apologies for the late reply.
I discovered last week after further testing that this issue is related to an extension that I use across all browsers.
I have reported the issue to the developers of the application.
Thanks
Glad to hear you found the root cause of the issue.
And thanks for your sharing!

Thanks :)
