Unable to change users password from PowerShell in Exchange Server 2016

Question

_{Monday, November 13, 2017 10:34 AM}

Hi all,

I was changing the password of a user mailbox from PowerShell and getting the following error (shown in screenshot). I have tried to use several passwords.

Below is the full command I am using,

 Set-Mailbox -Identity "karim buzdar" -OldPassword (ConvertTo-SecureString -string “@fakeid11” -AsPlainText -Force) -NewPassword (ConvertTo-SecureString -string “@Client1” -AsPlainText -Force)

However, I have successfully changed the password from ADUC.

Thank you,

Karim

You can try below :

$password = Read-Host "Enter password" -AsSecureStringSet-Mailbox -Identity "karim buzdar" -Password $password

Let us know how it goes

This says "you don't have permission to directly change a mailbox account password without providing old password". 

Reset password role is required for directly changing the password.

What is the problem with a method I mentioned before.

Thank you,

This error is due to the role group you are assigned to.

There is no problem with the method you've used, however the password you chose doesn't fall in your pwd criteria (as long as you've tried multiple\long password its is unusual indeed)

I've tried below and seems working, could you give it a try line by line

$oldpassword =  "@fakeid11"

$newpassword = "@Client100"

Set-Mailbox -Identity "karim buzdar" -OldPassword (ConvertTo-SecureString -string “$oldpassword” -AsPlainText -Force) -NewPassword (ConvertTo-SecureString -string “$newpassword” -AsPlainText -Force)

Please share output

I am getting the same error,

set-mailbox : The password you entered doesn't meet the minimum security requirements.

can you enter below commands and paste the output

Import-Module activedirectory

Alright..

Can you try the same commands below for your own account twice!

$oldpassword =  "edit"

$newpassword = "edit"

Set-Mailbox -Identity "youraccount" -OldPassword (ConvertTo-SecureString -string “$oldpassword” -AsPlainText -Force) -NewPassword (ConvertTo-SecureString -string “$newpassword” -AsPlainText -Force)

Please share output, this will help confirming password policy enforcement.

We are expecting it to work for the first time and give same error for the second time

minpasswordage is 1 day.

did you change the password within 1 day from ADUC?

you have to wait for more than 1 day and then try
