History and Recent Fixes:

August 7, 2021 Proxy Manager 4.0.0.1097

• Proxy Manager no longer relies on Basic Authentication alone (deprecated by Microsoft) and now supports OAuth2 authentication with Office 365 hosted mailboxes. After registering Proxy Manager as an application in the Azure Active Directory, Proxy Manager can function without Basic Authentication enabled in your organization. See step-by-step instructions on how to use Proxy Manager with OAuth2 authentication in Microsoft Azure.

 

November 15, 2020 Proxy Manager 3.3.0.1027

• New feature: Proxy Manager now allows to filter out certain SMTP addresses from being shown or used using include/exclude lists that support DOS-style wildcards * and ?.
  The lists can be defined either in HKLM (which would affect all users) or HKCU registry hives. Both lists are a ";" separated list of filters. See the how-to page for more information.
• New feature: Proxy Manager now shows the SMTP address the outgoing message was sent from or the incoming message was sent to in the "Email Account" column in the folder in Outlook (if the column is visible in the folder view).
  
   
• Bug fix: for some Exchange Servers utilizing NTLM authentication, no messages could be sent and no NDR generated.
• Bug fix: on a received message, if both the primary user and one of its delegate mailboxes were present as recipients, Proxy Manager on a reply/forward could sometimes default to the delegate address instead of the matching address from the primary mailbox.

 

December 8, 2019 Proxy Manager 3.2.0.987

• In a multiuser environment (such as RDS), options global to all users (e.g. the RegistrationKey, Timeout, or CanEditNames) can be set in the HKLM registry hive rather than HKCU, making it possible to for the administrator to enter the keys only once and have it used by all users on the machine.
  You can also set DefaultServer , DefaultPort , and DefaultEncryptionKind options that will be used as the default template when a local user uses or configures Proxy Manager for the very first time.

 

October 19, 2019 Proxy Manager 3.1.0.921

• Bug fix: disabled addresses were still displayed in the "From" dropdown.
• Bug fix: sending a message using Proxy Manager to a private Distribution List (from one of the Contacts folders) produced a non-delivery report (Could not retrieve an SMTP address).
• Bug fix: Proxy Manager Options dialog was sometimes invisible (thus locking Outlook) if Outlook main window was shown on a secondary monitor.
• The installer now includes both 32 and 64 bit versions - there are no more separate installers.

 

April 7, 2019 Proxy Manager 3.0.0.871

• New: Proxy Manager now now supports per-email address signatures. Whenever a new message or a reply is created, the appropriate signature is selected. Selecting a different address  for which a signature is specified, will insert (or the replace the old signature with) the signature associated with that address.
  

 

February 16, 2019 Proxy Manager 2.8.0.749

• Bug fix: When replying or forwarding using an inline reply in Outlook 2016 (January 2019 update), the reply would get sent, but it would also sometimes pop up in a separate inspector instead of just closing.
• Bug fix: Proxy Manager would sometimes fail to show its Options dialog box when clicking File | Proxy Manager Options in Outlook.

 

January 24, 2019 Proxy Manager 2.7.0.725

• Bug fix: it could take a log time for the Options dialog to appear on machines configured with invalid or slow DNS servers.
• Bug fix: if the Exchange account password was updated, but Proxy Manager still used the odd password, the messages could be successfully sent, but a copy would be left in the Outbox folder.
• New: Proxy Manager now allows to add arbitrary SMTP  addresses. Note that this feature only works with non-Exchange SMTP servers as Exchange Server does not allow sender address spoofing. Right-click on the address list to add an extra address.:
  

 

November 25, 2018 Proxy Manager 2.6.0.675
This releases focuses primarily on the performance and stability issues.

June 9, 2018 Proxy Manager 2.5.0.515.
This releases focuses primarily on the performance and stability issues.

• New: Proxy Manager is now optimized to work with large (100+) number of aliases and is much faster even with smaller lists.
  Note that icons were removed from the address drop down due to a GDI object leak in Outlook (which can lead to an Outlook crash).
• New: On June 1, 2018, Microsoft turned on an Office 365 feature that will cause all messages sent through SMTP to be automatically saved in the Sent Items folder. This will cause duplicates if a message is sent using an older version of Proxy Manager.
• New: You can now hide some proxy SMTP aliases from the address dropdown:
  

April 22 2018 Proxy Manager 2.4.0.491

• New: Proxy Manager now automatically picks up and allows to send through the SMTP addresses of all delegate Exchange mailboxes on whose behalf the current user has the right to send messages ("Send on behalf" permission on the Exchange Server).
• Bug fix: Proxy Manager always saved the sent message in the default Sent Items folder instead of checking if the message was set by the user to be saved in a different folder.
• Bug fix: Proxy Manager could not connect to an SMTP server through DirectAccess or if the SMTP server was only accessible through IPv6.
• Bug fix: Proxy Manager sometimes caused Outlook to crash if it was manually disabled from File | Options | Addins in Outlook.
• Bug fix: in case of multiple mail accounts, Redemption did not sort the email addresses based on the order of the accounts (with the default account coming first).

• Sending a signed/encrypted message sometimes created and NDR with the IMessage.CopyTo: MAPI_E_CALL_FAILED error.
• Proxy Manager now keeps its credentials in sync with the credentials used by Outlook - if Exchange account password changes, you do not need to enter the new password in Proxy Manager.
• Proxy Manager sometimes created an non-delivery report even if the message was successfully submitted if the SMTP server unexpectedly terminated the connection after the message was transmitted but before Proxy Manager attempted to log off.
• Proxy Manager now allows to reclaim the license key by deleting the license on a machine where it was previously installed (Options | Register dialog box).

November 11, 2015 Proxy Manager 2.1.0.281

• Added support for Outlook 2016

• By default, Proxy Manager always defaults the reply address to the proxy address to which the original message being replied to was sent.

Unchecking that option forces Proxy Manager to default to the primary SMTP address of the Exchange account (unless another address is selected).
• Editing of the display names associated with the proxy addresses by the end user can now be prevented by creating a DWORD registry value named CanEditNames with the value of 0 in HKEY_CURRENT_USER\Software\AdvancedMessagingSystems\ProxyMan

• You can now specify the SMTP connection timeout (10 seconds by default) when using a high latency connection. Create a Timeout value (either string or DWORD) in HKEY_CURRENT_USER\Software\AdvancedMessagingSystems\ProxyMan
  The value is in milliseconds; for example, to set a 60 seconds timeout the registry value must be 60000.
