September 2022: version 1.07

Update for users on office 365. Basic Authentication will be disabled soon for Office 365 so Category Manager now uses oAuth for Office 365.

Update instruction:

To update to this version download the trial version zip file.
Extract the zip and take catadmin.exe, ExchangeCategoryManager_EWS.exe, Microsoft.IdentityModel.Abstractions.dll and Microsoft.identity.client.dll and replace them on your server. (after stopping the ecm service)

 ExchangeCategoryManager must be added to your Azure AD like this:

Step 1: open a powershell console as administrator (elevated)

Step 2: make sure it uses tls 1.2 by running this command:  [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Step 3: run this command:  Install-Module -Name AzureAD      and answer A (yes to all). This may take a while, be patient.

Step 4: When you are back at the prompt run the commands below but make sure to change the section "yourID" into the tenant id of your Azure AD. (leave the quotes, only replace the word yourID). You can find your tenant ID in Azure Active Directory admin center - Overview

Connect-AzureAD -TenantID "yourID"  

new-AzureADServicePrincipal -AppID "238830b1-4b78-4feb-a84f-acd1ffea3b53" -DisplayName "ExchangeCategoryManager" -Tags {WindowsAzureActiveDirectoryIntegratedApp}

Step 5: Open your azure active directory admin center in the browser and find the exchangecategorymanagerr application under Enterprise applications.

Select it and under permissions click "grant admin consent"

Now open catadmin.exe on your server and enter your tenantID. (you already looked that up in the previous steps)

Click the button to verify credentials and look at the text box at the bottom for it's progress. If there are no errors you can start the ecm service again.  (if you get error 401 and you already retyped the password so you are sure it is correct, try it without the " @domain.com " part of the email address. So just the name.)

If you get an error that there was a connection problem, make sure TLS1.2 is enabled on the computer from where you run the software. (google this "enable tls 1.2 registry")

Januari 2020: Version 1.06  You can now tell the software to use TLS1.2 (if TLS1.0 and 1.1 have been disabled on your server) For this add to the config.ini file
[UseTLS1.2]
Value=True

April 2019 : Version 1.05. Password in catman console now encrypted plus a new option to delete individual categories from the category list of the users. (to update, replace the executables on your server by those in the trial version zip file. Important: Enter the password of the catmanadmin in the console again after updating.

August 2017 : small update to remove an error in the first  log file when using office 365 - version 1.04

April 2017 : No updates required for exchange server 2016.

4/23/14 : Users that never used categories had to manually create one custom category before the software was able to manipulate their category list. This has been fixed. The CatMan software now creates the categorylist for them.
