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. This I did (I simply created new mail profiles and let auto discover do its work). But then the Outlook clients...
Public Folder Migration Error hr=0x80040111
KB ID 0001228 Problem I usually follow my own documented process for migrating public folders to Exchange 2016. I did that this week, and this happened; Error; MapiExceptionLogonFailed: Unable to make connection to the server.

Setting Up Meraki MDM
KB ID 0001226 Problem As is usually the case with Meraki this is pretty simple to setup. If you are familier with Meraki and have not deployed MDM before then stop a second. I mistakenly setup a dashboard for a client recently, (like I usually do with Meraki deployments). Then could not work out how to add the MDM component without an order number! Meraki MDM is free (up to 100 devices) which is great, but BE WARNED, register 101...
Exchange 2016 – EAC (ECP) Works But OWA Does Not
KB ID 0001225 Problem During an Exchange 2010 to Exchange 2016 Migration, I was busy migrating mailboxes into the 2016 mailbox database. I noticed that while the Exchange Admin Center worked fine (I was doing the migration from there!) Outlook Web Access did not. I got a ‘Something Went Wrong” error. 🙁 Something Went Wrong We Cant get the information right now. Please try again later. More Details Refresh the page...
Exchange 2016 (& 2013) Enable Circular Logging
KB ID 0001224 Problem Let’s be clear about this, the correct way to flush/clear the Exchange logs is to perform a backup of the mailbox database in question, with an ‘Exchange aware’ piece of backup software. This will clear down the logs properly. Why Do We Need Logs? Well I’m glad you asked, if there’s a problem, and we lose the database, we can ‘play’ the log files back into the database to...
IIS – Cannot Download File From Website (With Extension .xyz)
KB ID 0001223 Problem I first saw this problem a few months ago, when I wasted to download some .bin and .pkg files from a web server running IIS, into a Cisco firewall. Then again this week I needed to get a large .iso file into a clients network so I put it on a publicly accessible web server running IIS, and had the problem again. Solution On the IIS server, open administrative tools > Internet Information Services (IIS)...
The name of the security certificate is invalid or does not match the name of the site
KB ID 0000036 Problem Seen in Outlook when connecting to a mailbox on an Exchange Server, its caused by using a self signed certificate OR a purchased certificate, where the internal and external names are different. The name of the security certificate is invalid or does not match the name of the site. Solution Before proceeding if you have an A or CNAME record in your DNS for autodiscover then DELETE it and setup an SRV record!...
Android – Stop ‘Facebook’ Messenger Hijacking Your SMS
KB ID 0001222 Problem Just because Facebook changed the name to simply ‘messenger’ then had it as a separate ‘app’ to confuse the masses into thinking it was nothing to do with Facebook, does not mean I want it to handle my SMS messages! I already have something to handle my SMS messages, MY PHONE! Yes it’s running Android so I’m slowly giving my soul to Google, but that doesn’t mean Facebook...

While installing a new Exchange 2016 Server into a clients Exchange 2010 infrastructure last week, the setup failed with the following error.
