How to locate your missing emails (IPM_subtree)

Today I ran into a little problem. For some reason I moved all my emails from a particular folder into a unknown other folder. I could find the email(s) using the search option and found out that the specific files were located in the IPM_Subtree folder.

After some investigating I found out that it was quite easy to locate these files and move them back again to their old location.

First download MFCMAPI here.

Assuming the missing emails are in the IPM_SUBTREE folder, do the following.

  1. Download the MFCMapi program above, and run it from the client PC that the user connects from (no installation necessary). MFCMapi uses Outlook profiles to get server information and connect. You can connect directly using your Outlook profile.
  2. Go to the Session menu, then “Logon”.
  3. Choose the Outlook profile and click OK.
  4. Locate the main mailbox to open, and double-click it to open.
  5. Expand “Root Container” and locate “IPM_SUBTREE”.
  6. Right-click on “Top of Information Store” and select “Open Contents Table”. Note: You may see an entry called “IPM_SUBTREE” instead, this is the same folder as “Top of Information Store”.
  7. A new window will open, and will show any messages in the “IPM_SUBTREE” folder. Select all that show up, and right-click and select Copy.
  8. Navigate to the Inbox (or alternative folder), under the Root Container / Top of Information Store / Inbox. Other folders will appear here as well.
  9. Right-click and select Paste to move the messages found in to the Inbox folder.
    You can choose to move the emails instead of copying them.
  10. The messages should now show up in Outlook once again.

How to migrate from Evernote to OneNote

For the last couple of years I’m using Evernote. And frankly.. I’m quite happy with Evernote. But besides Evernote, I’m also using EverNote for Business purposes and why not use EverNote for both of them?

Evernote Premium costs $ 49,99 or $ 59,99 yearly and when you are already using Microsoft Office 365 ($69,99 yearly) that seems a bit unnecessary.

I never investigated how to migrate from EverNote to another solution but found out that’s be very easy. Microsoft developed a migration tool which is very easily to use.

Download the Migration tool here:


Make sure you have the Evernote tool installed on your device. Alright let’s start the migration tool:


Click to accept the License terms. ūüôā


Choose the Evernote content you wish to migrate.


Sign in with your Microsoft OneNote account and the migration starts off! Depending on your number of notes it can take some time.

The migration tool creates a new tab for every 100 notes :

Invalid Exchange Server version using Veeam Backup for Microsoft Office 365 #updated #withSolution

Update: After contacting Veeam support they attended me that there is a private fix voor version 912.

  • stop all jobs
  • stop “Veeam Backup for Microsoft Office 365 Service”
  • replace Veeam.Ews with the DLL from the archive¬† in C:\Program Files\Veeam\Backup365 (don’t forget to back up the original DLL)
  • Start “Veeam Backup for Microsoft office 365 Service”
  • retry the job


As you can see the problem is solved and I’m able to backup Office 365 again!

People (including me :-))  are reporting problems using Veeam Backup for Microsoft Office 365. It seems that Microsoft made some kind of change on their back-end. At this time Veeam reports that they are looking into the problem..

I’m running Version…. a newer version isn’t available on the general download site. So upgrading the Veeam software isn’t the solution for now.


Don’t seem to be (Windows) update related. Before and after updating my test server I receive the same error. ūüôĀ


When there is a solution I shall mention this in this blogpost.

How to Add an extra email address to your O365 mailbox the right way

This blogpost describes how to add an extra email address on your O365 mailbox. Someone told me that when he tries to add an extra email address using the Office 365 admin partner he receives the following error :


The error says that this action (adding an extra email address) should be performed on the object in your on-premises organization. This means that your Active Directory is connected to Azure (O365). So extra email address should be added on the specific user properties and not directly using the Exchange admin interface. Your changes are automatically replicated to Azure.

Go to your domain controller and open dsa.msc (Active Directory Users and Computers) and go to the user you wish to provide an extra email address. Important : don’t search for this specific user, this way you don’t see all the properties later on. Also make sure that you have the advanced view enabled in dsa.msc, otherwise you won’t see the Attribute editor tab.


Open the properties of the specific user and select Attribute Editor and go to ProxyAddresses. Now you have the option to add an extra emailaddress, use the following Value :

Make sure that the domain is registred correctly in O365.

How to revoke App Access to your Office 365 environment

Today I tested a backup solution¬†for Office 365. Installation was very easy and within seconds I made a connection to my Office 365 test environment. I quickly entered my admin creds and hit enter a couple of times. ¬†Hmmm…. that went very smooth. The backup application made sure that there were enough permissions.

Okay, now I ready with the product evaluation. I want to remove those credentials! But how…. I found out that I had to look for it, so I thought it would be a nice idea to share my experience with my readers..

Login to your Office 365 tenant with Admin creds and go to the upper right and choose the options icon next to your name.


Go to Office 365.


You see all the applications that have (administrative) access to your tenant. You notice many default (web) apps. But notice the last application, Office 365 Backup. Click on details to verify that you have the right application. Ok? Now let’s remove those permissions. You can’t do this in this windows however. First you must go the My Account, and then notice the App permissions Pane. (3rd pane)


Now click on the three dots next to your application:


Choose the remove from tenant option. Et voila, your permissions are removed :


(Notice that the Office 365 Backup permissions are gone)

Nowadays more and more Office 365 tools & software is coming to the market. It would be nice that when uninstalling the product, the vendor also removes the permissions made..

How secure is your Office 365 environment?

More and more companies are using Office 365 (O365) nowadays. Because it’s a SaaS service many people think that they don’t have to think about security. This is a common made mistake.

Log on to with you (admin) Office 365 credentials and you see your current score. (Pictures taken from demo environment)

O365 1

You immediatly notice your score and the maximum score you can achieve. A nice feature is that you can see what your score was days/monts ago.  Maybe someone made an adjustment to your O365 configuration which has security consequences.

Secure o365 time

Notice the information about the security measurements you already took and the one you can/need to take to improve your security score.

Security O365 Done

Security O365 open

It’s very easy to show more information about the steps. Just expand the specific action and choose how to accomplish that step.

How to show (export) all devices synchronizing with your Office 365

For a MDM project I had to make an dump which users are using which devices to (active)sync with their Office 365 mailboxes. This is how I did that :

Get-Mailbox -ResultSize Unlimited | ForEach {Get-MobileDeviceStatistics -Mailbox:$_.Identity} | Select-Object @{label=”User” ; expression={$_.Identity}},DeviceModel,DeviceOS, lastsuccesssync | Export-csv F:\powershell\activesync.csv

Running the above command showed the following output (in a CSV file format):

As you can see you see the user, the device the user is using, the OS their device uses and last time that devices succesfully synchronized.

I used Excel to import the CSV and sort on LastSuccessSync.
