Intermittently ECP access denied on local computer
when trying to access ecp from user local machine intermittently we will get the http error 403, access was denied. however if we refresh the page couple time it will eventually let us through. this behavior only observed in local computer, if we try to access ecp from exchange server the issue cannot be reproduced. if anyone encounter such issue before and any resolution so far. Thank you in advanced.
Exchange 2019 CU 12 update - One DC object not found in ECP
Hello, The environment consists of one domain, one EX2019 server and DC1 and DC2 which are replicated. After upgrading Exchange 2019 to the latest CU 12 release, when selecting on objects in the virtual directories list within ecp, the following message appears on the right side where the virtual directory: 'The operation couldn't be performed because object '' couldn't be found on 'dc1.domain.local'. - Screenshot attached. Unselecting and selecting it again, resolves this and the information is now displayed properly. This happens with all virtual dirictory items upon initial selection in the panel. The error message in the Command Logging tool is: \"+e)}}return!0}return Logger.info(\"performSourceBufferOperation(): Raw source buffer not instantiated yet.\"+e),!1}catch(g){return Logger.error(\"performSourceBufferOperation: Exception:\"+g.message+e),!1}},this.processAddSourceBufferMessage=function(a){var b=this,c=null;if(!a||typeof a.id!=\"number\"||typeof a.mimeType!=\"string\")return Logger.error(\"processAddSourceBufferMessage(): Invalid parameter.\"),!1;if(this._mediaSource==null)return Logger.error(\"processAddSourceBufferMessage(): Media Source is NULL.\"),!1;if(!MediaSource.isTypeSupported(a.mimeType))return Logger.error(\"processAddSourceBufferMessage(): MimeType is not supported.

Error "There are more results available than are currently displayed" after May 2022 installation
I recently installed May 2022 security update on my Exchange 2016 CU22 DAG. I restored the customization on web.config of ECP to display all OU from ECP (https://docs.microsoft.com/en-us/exchange/troubleshoot/administration/exchange-server-not-display-all-ou) , but it does not work at all neither after a recycle bin nor an IISreset on the server. When I check the PoSh command executed it is still "Get-OrganizationalUnit -IncludeContainers:$true -ResultSize 500" whereas it should be with 1500 according to the change I made in the web.config file. Did someone have the same issue? Thanks for your help
AADconnect with Exchange server but without Hybrid Config - Managing users
Hi, We have all of our mailboxes in Exchange Online. MX records point to Exchange Online. Autodiscover points to Exchange Online (autodiscover.outlook.com). These were migrated to O365 from a previous project (previous supplier). I have a new on-premises Active Directory forest. I have configured AADConnect server and will be syncing my new AD users to Azure. I will also be hard matching the Exchange Online mailboxes to my on-premises AD users (using immutableID command. Not an issue). As I have installed a new Exchange 2016 environment, I want to see the Exchange Online mailboxes visible in my on-premise Exchange ECP. I want to do this without having to set up a Hybrid Configuration. The reason is, There is no need for Free/Busy, no need for mail to route across on-prem and EXO - because, Autodiscover points to Outlook.com, MX records point direct to Exchange Online. I just want to be able to see the Exchange Online mailboxes displayed as "Office 365" mailboxes in my on-premise Exchange 2016 so IT admin team can do BAU activities such as changing Exchange related attributes (e.g. hide from address list) etc from on-prem. Or even be able to create a new remote mailbox from Exchange on-prem. Thanks Ron
