Exchange ‘Cross Forest’ Mail Migrations
KB ID 0001356 Problem PeteNetLive is full of Exchange Migration walkthroughs, going all the way back to Exchange 2003. But what if you are migrating to another forest? Well for small migrations you can of course export mail from the old Exchange Server, and them import it into the new mailbox in the new domain/forest (usually via .PST files). I’ll provide links at the bottom of the page, if that’s what you would prefer to...

Microsoft Exchange – Forwarding Mail To External Email Addresses
KB ID 0001350 Problem Note: Below I’m using Exchange 2016, but the same approach will work for previous versions. There are a load of reasons why you might want to do this, but before you go off in this direction consider why you are doing this in the first place. For example, if the user requesting this does not need an Exchange mailbox, i.e. because they only use their Gmail account then it’s probably a better idea to...
Exchange Bulk Export / Import Mail Contacts
KB ID 0001349 Problem I had to do this today and realised, it’s been so long since I did it last, I’d forgotten how to do it. Before we go forward, please be clear, I’m talking about MAIL CONTACTS, these are Active Directory Objects that have an Email address, but DO NOT have a mailbox in your Exchange Organisation, and DO NOT have an Active Directory User. I point this out because you can have MAIL USERS that have...
Exchange AutoDiscover Errors – Creating an AutoDiscover SRV Record
KB ID 0001184 Problem Ages ago I wrote the following article; Outlook Error “The name of the security certificate is invalid or does not match the name of the site.” You used to see this error a lot if your internal, and external domain names were different, and the ‘public’ domain name was on the certificate, in those cases I’d also setup split DNS like so; Windows – Setting Up Split DNS But you can simply create a...

Exchange – Cannot Delete Mailbox Move Request
KB ID 0001228 Problem On the tail end of an Exchange 2010 to 2016 migration last week, I needed to decommission the old Exchange 2010 server. It would not let me remove the mailbox database, as it had a ‘move-request’ that it thought had not completed, (for the administrator account). However if I tried to delete the move request from the EMC this happened; Error Failed to communicate with the mailbox database...
