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. Looking at the queue viewer, I could see that all their mail was sat in queues waiting to go into their mails stores. There was a queue for each mail store, and the error on each was “451 4.4.0 DNS query failed Exchange Server error in message queue”. Looking in the Application log it was full of Event ID 205, and 16025 Errors...

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. This I did (I simply created new mail profiles and let auto discover do its work). But then the Outlook clients...

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...
