This one is an interesting one – and it was only resolved by a call to Microsoft Support, who do not document that this setting is required. The scenario is that you upgrade your CRM Router to v9 (as this is required before you upgrade Dynamics to V9) and you enable TLS 1.2 on the… Continue reading CRM Router and Dynamics CRM V9 Online–No Emails Being Processed

Exchange Server Dependency on Visual C++ Failing Detection
Exchange Server for rollup updates and cumulative updates at the time of writing (Feb 2019) has a dependency on Visual C++ 2012. The link in the error message you get points you to the VC++ 2013 Redistributable though, and there is are later versions of this as well. I found that by installing all versions… Continue reading Exchange Server Dependency on Visual C++ Failing Detection
451 4.7.0 Temporary server error. Please try again later. PRX2
There are a few articles online about this error, but none were correct for the scenario i found a clients network in. Not that I think the specifics matter, but this was Exchange Server 2016, Windows Domain Controllers running 2012 R2 and Exchange Hybrid. All the mailboxes had already moved to the cloud and the… Continue reading 451 4.7.0 Temporary server error. Please try again later. PRX2
Public Folder Migrations and the Changing Cmdlets
To complete a public folder migration from Exchange 2013/2016 to Exchange Online you need to run Set-OrganizationConfig -PublicFolderMailboxesLockedForNewConnections $true But if you look at lots of the documentation that is out there with their tips and tricks etc. you will see that lots of them say: Set-OrganizationConfig –PublicFoldersLockedForMigration $true So very near – but its… Continue reading Public Folder Migrations and the Changing Cmdlets
Test Connectivity Website and TLS 1.2
An excellent resource for Microsoft Exchange Server and Exchange Online administrators and consultants is the Remote Test Connectivity website at http://exrca.com or https://testconnectivity.microsoft.com/. Here I am going to document an error that indicated that the Exchange Server (in this case) was not working, but we could see that the phone was connecting fine to the… Continue reading Test Connectivity Website and TLS 1.2
Public Folder Sync–Duplicate Name Error
I came across this error with a client today and did not find it documented anywhere – so here it is! When running the Public Folder sync script Sync-ModernMailPublicFolders.ps1 which is part of the process of preparing your Exchange Online environment for a public folder migration, you see the following error message: UpdateMailEnabledPublicFolder : Active… Continue reading Public Folder Sync–Duplicate Name Error
CannotEnterFinalizationTransientException On Exchange Move Request
Did not find a lot on the internet on this particular error, so I guess it does not happen very often, but in my case it delayed to move of the mailbox in question by a week or so until I could resolve it. When a mailbox is moving to a different Exchange organization (cross-forest… Continue reading CannotEnterFinalizationTransientException On Exchange Move Request
Exchange Server Object ID Error With Windows Server 2016 Domain Controllers
Saw this error the other day: When you open Exchange Control Panel and view the Mailbox Delegation tab of any user account you get the following: The object <name> has been corrupted, and it’s in an inconsistent state. The following validation errors happened: The access control entry defines the ObjectType ‘9b026da6-0d3c-465c-8bee-5199d7165cba’ that can’t be resolved..… Continue reading Exchange Server Object ID Error With Windows Server 2016 Domain Controllers
Copy Links and Backlinks Between Users and Shared Mailboxes (automapping)
Automap for shared mailboxes does not work across forests when moving mailboxes. When the user is granted permission to a shared mailbox, the default behaviour of automapping means that the shared mailbox has msExchDelegateListLink set to the DN of the user, and the backlink (hidden in AD by default) on the user is populated with… Continue reading Copy Links and Backlinks Between Users and Shared Mailboxes (automapping)
Anonymous Emails Between On-Premises and Exchange Online
When you set up Exchange Hybrid, it should configure your Exchange organizations (both on-premises and cloud) to support the fact that an email from a person in one of the organizations should appear as internal to a recipient in the other organization. In Outlook that means you will see “Display Name” at the top of… Continue reading Anonymous Emails Between On-Premises and Exchange Online
Send-On-Behalf Permissions in Exchange Online

First, Send-On-Behalf is changing so that it is supported across a hybrid Exchange Server to Exchange Online connection. At the time of writing this is… Continue reading Send-On-Behalf Permissions in Exchange Online
420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address
This error can turn up in Exchange Server when Exchange Server is trying to resolve the object that it should deliver a message to. Exchange queries Active Directory and expect that if the object exists in the directory, that the object exists only once. If the object exists more than once, this is the error… Continue reading 420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address
Exchange Online Migration Batches–How Long Do They Exist For
When you create a migration batch in Exchange Online, the default setting for a migration is to start the batch immediately and complete manually. So how long can you leave this batch before you need to complete it? As you can see from the below screenshot, the migration batch here was created on Feb 19th,… Continue reading Exchange Online Migration Batches–How Long Do They Exist For
Office 365 Retention Policies and Hybrid Public Folders
If you create an Office 365 Retention Policy (in the Security and Compliance Center) that applies to all Exchange Online content then you might find that after the retention policy has been deployed (a day or so later usually) that the policy is in error and there is a message at the top of the… Continue reading Office 365 Retention Policies and Hybrid Public Folders
Journal Rule Testing In Exchange Online
I came across two interesting oddities in journaling in Exchange Online in the last few weeks that I noticed where not really mentioned anyway (or anywhere I could find that is). The first involces routing of journal reports and the second the selection of the journal target. The journal report, that is the message that… Continue reading Journal Rule Testing In Exchange Online
Outbound Email Via Exchange Online Protection When Using Hybrid Exchange Online
In a long term hybrid scenario, where you have Exchange Online and Exchange Server configured and mailboxes on both, internet bound email from your on-premises servers can route in two general ways. The first is outbound via whatever you had in place before you moved to Office 365. You might have configured Exchange Online to… Continue reading Outbound Email Via Exchange Online Protection When Using Hybrid Exchange Online
