Hi @Deen Uthman

Kindly note that since Exchange 2013 has reached end of support in 2023.4.11, if possible please consider upgrading to Exchange 2016 or 2019 for better support.

If the requirement is to simply disable mailbox for these users (not also delete their AD accounts), you can prepare a csv file with the format like:

Add the mailboxes' email addresses you would like to delete in the csv file, then run the following script in Exchange Management Shell:

import-csv C:\public\disable_mailbox.csv | foreach{Disable-Mailbox -identity $_.EmailAddress -Confirm:$false}

If you would like to also delete the AD accounts, modify the script to:

import-csv C:\public\disable_mailbox.csv | foreach{Remove-Mailbox -identity $_.EmailAddress -Confirm:$false}

Yes, the PowerShell command worked perfectly. Had an issues with a number of account that would not bulge, kept coming up with access denied restrictions error message, so I had to enable the AD user account inheritance security parameter. Once I changed it, tried again and was able to delete the remaining accounts.
