How To Install Exchange 2016 (Greenfield Site) – Part 1
KB ID 0001301 Problem As the title implies, this article assumes you do not already have Exchange of any flavour in your organisation.

Solution Firstly, you need to have purchased the new domain name, and have the DNS records setup properly for the new domain name. See the following article; Setting up the Correct DNS Records for your Web or Mail Server Add...

OWA 2016 – Change Login From Domain\Username to Username
KB ID 0001254 Problem Out of the box, if you want to log into Outlook Web App, you need to use the Domain\Username format, like so; Seeing as how Microsoft are making a big song and dance about using UPN’s to log into Office 365, I thought they might have changed from the NT4 way of doing things, but hey what do I know? As we all know users are stupid, Domain\Username is up there with string theory and quantum mechanics. So how...
Outlook Web App :-( Something Went Wrong

Exchange – Event ID 205 and Event ID 16025
KB ID 0001251 Problem At a client this week, they were having a LOT of mail flow problems.

Exchange Renaming and Moving Databases
KB ID 0001229 Problem Exchange has a habit of naming its databases as ‘Mailbox Database {Random-Number}’. This makes my OCD ‘itch’. So one of the first things I do is rename the database to something more sensible. Then I like to move the databases from the server system drive, and also relocate the log files into their own partition/drive. Solution Rename a Mailbox Database Log into Exchange Admin Center >...
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...
Outlook – Constantly Prompts for a Password
KB ID 0001227 Problem I did an Exchange 2010 to 2016 Migration for a school this week. They are going to reimage all their PCs to Windows 10 and install Office 2016 over the summer holidays. But a few staff members were working over the holidays and needed their Win7/Outlook 2010 clients pointing to the new Exchange server.
