Do they use Auto-Mapped mailboxes?

 Had this issue with a number of staff here directly after migration from 2010 to 2016


$mailboxes = Get-MailboxPermission -Identity * -User <username> | Select -ExpandProperty Identity

Foreach($mailbox in $mailboxes){Remove-MailboxPermission -Identity $mailbox -user <username> -AccessRights fullaccess -Confirm:$False}

Foreach($mailbox in $mailboxes){Add-MailboxPermission -Identity $mailbox -User <username> -AccessRights fullaccess -AutoMapping $false -Confirm:$False}

Wait a few mins then see if the user can open Outlook.

If you are looking to Migrate a classic VM in Azure to ARM , you will need to change your Endpoint port forwards via a Load Balancer

Go to the Azure portal:

Click “NEW” -> write “Load Balancer” in search field -> Click “Load Balancer”

After you have clicked the “Load Balancer”, click the “Create” button.

Then fill out the configuration blade as shown below:

Azure will take a few minutes to create the Load Balancer.


Once created, your resource group will look like this:

Step 2: Configure Load Balancer Backend Pool

In order to connect our newly created load balancer to our virtual machines, we need to create a so-called “Backend Pool”.

To do so click on your load balancer to open its configuration blade.

Click on the item called “Backend Pool” in the menu to the left:

Then click the “Add” button:



Fill out the “Add backend pool” configuration blade as shown below:

Now click on “+ Add a target network IP configuration”:



…and select the IP configuration for your virtual machine:



Finally, click the “OK” button to save the Backend Pool.

Now repeat this step;  but this time choose VM1 instead of VM0.

All in all, this will give us two backend pools pointing to VM0 and VM1 respectively:

It will take Azure 1-2 minutes to create the Backend Pools

Step 3: Configure NAT rules

Now our load balancer is connected to our virtual machine and we now need to configure rules for redirecting network traffic.

Start by clicking “Inbound NAT Rules” in the menu to the left:

Then click the “Add” button:

Fill out the “Add inbound NAT rule” configuration blade as shown below:


Now repeat this step, but this time choose VM1 instead of VM0 .

We will now end up with two Inbound NAT Rules: one with port 8088 associated to VM0 and one with port 8089 associates to VM1 :

rdm_basic1It might be worth checking if these still need to be RDM’s. This was previously used for older versions of VMDK’s could only use 2TB , now with esx 5.5 and Virtual Machine hardware 10 this is upped to 62TB

Changed Pysical RDM to Virtaul RDM to VMDK’s

Use the webclient for this

1) Shutdown the server
2) Upgrade the Virtual Hardware to 10
3) Remove the Physical RDM Lun
4) Re-Add the Lun as Virtual
5) Power on server
6) Storage VMotion to New SAN


FYI Virtual RDM’s cannot be resized without shutting down the machine unlike Physical

sendonbehalfofSent items dissappear during an exchange migration between operators and secretaries due to mixes of Exchange 2010 and 2003 for example:

  • Exchange2003User1
  • Exchange2003User2
  • Exchange2010User3


Current Enviroment 2003 : When I send from Exchange2003User1 onbehalf of Exchange2003User2 at the moment it puts the email in the Sent Item of Exchange2003User1


Secretary 2003 and Operator 2010 : When I send from Exchange2003User1 ( 2003 Mailbox ) onbehalf of Exchange2010User3  it replicates the above and puts the Sent Item of Exchange2003User1


Secretary 2010 and Operator 2003 : When I send from Exchange2010User3 onbehalf of Exchange2003User1 the sent email disappears ( does not get stored anywhere )


This means we will need to migrate all the operators before the secretaries move, and the secretaries can move one at a time after. Hope this helps now with UAT group!

Exchange Commands

In Exchange 2010 you can configure this server side to duplicate to both sender and from address.

Set-MailboxSentItemsConfiguration <mailbox id> [-SendAsItemsCopiedTo [Sender|SenderAndFrom]] [-SendOnBehalfOfItemsCopiedTo [Sender|SenderAndFrom]]

Outlook Commands

*NB Outlook will need to be in Cached Mode

Consider the following scenario. You use Outlook 2010 and are a delegate for your manager. Even though theDelegateSentItemsStyle registry value is set to 1, an email message that you send on behalf of your manager is saved in yourSent Items folder.

Key: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences
Name: DelegateSentItemsStyle
Value: 1
