Exchange – Cannot Delete Mailbox Move Request

KB ID 0001228 


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;

Cannot remove Move Request


Failed to communicate with the mailbox database

MapiExpetionNoAccess Unable to open message store

(hr=0x080070005, ec=-2147024891



Even trying to remove the move request with PowerShell failed. In the end I had to remove the request in ADSIEdit.msc. 

Windows Key+R > asdiedit.msc > Connect to > Default Naming Context > DC={your domain}, DC={your domain extension} > Navigate to the user affected > Properties > Filter > Show only attributes that have values.

Remove Exchange Move Request

Locate the following two values and clear them;



Remove Exchange Move Attributes

This is enough to remove the failed mailbox move request, but if you’re nervous, then just refresh the move request section and it should disappear.

  1. Wunderbar ! Ich könnte Sie umarmen! Ich habe dringend eine Möglichkeit gesucht alt -User aus dem AD
    dem neuen Exchange wieder hinzuzufügen. Das ging nicht, weil alte Exchange Attribute den Usern
    anhafteten. Mit Ihrer Methode konnte ich sie alle löschen auf einem WS 2016 DC.
