Total Access Emailer and Office 365 SMTP with TLS

Posted on by

Total Access Emailer is the most popular email automation system for Microsoft Access. Total Access Emailer uses your SMTP server to send emails. A popular choice is the SMTP server provided by Microsoft Office 365’s Exchange Server.

Total Access Emailer and the Office 365 SMTP Server

Total Access EmailerAssuming the account is properly configured to relay email messages (Mailbox Delegation), Total Access Emailer has supported Office 365 since it was introduced.

Over the years, Microsoft has increased security on their site and adjusted configurations for their SMTP server. You can connect via SMTP protocol using an approved IP address or Transport Layer Security (TLS) protocol for a specific email address.

Instructions for configuring Office 365’s SMTP server are provided here:
Office 365 SMTP Relay Configuration to Send Emails via the Office365 Exchange Server

Problem with TLS Connections

In the last week, we confirmed that Office 365 and Windows made changes that cause Total Access Emailer to be unable to send emails with its TLS connection protocol with an error like this:

SMTP protocol error: TLS 1.0 and 1.1 are not supported

The message implies the need for TLS 1.2, but recent versions of Total Access Emailer already support TLS 1.2.

What is not supported is TLS 1.3 that recent changes with the Office 365’s SMTP server and Windows seem to require. Here’s a Microsoft article about TLS 1.3: Taking Transport Layer Security (TLS) to the next level with TLS 1.3.

NOTE: TLS still works with many other SMTP servers including Gmail’s smtp.gmail.com (details for Using Total Access Emailer and Gmail).

Workaround: Use SMTP Protocol

If you are having trouble using TLS protocol, the SMTP protocol still works for Office 365. You need to authenticate your IP Address where you’re sending the emails. Remember to use the Temail.txt to store the FROM email address to use for validation as instructed in the referenced page above.

We realize that is not possible for all the environments of Total Access Emailer users.

New Versions of Total Access Emailer

This has accelerated our ongoing development for a new version of Total Access Emailer to address the new protocols. Our development team has already created a solution that is working with the new protocols and hope to release it, as soon as it completes thorough testing. We expect to release these Access 32 and 64-bit versions:

  • New Product:
    • Total Access Emailer 2021 for Access 2021, 2019 and the current Office 365 version
  • Updates:
    • Total Access Emailer 2016
    • Total Access Emailer 2013
    • Total Access Emailer 2010

New versions are now available! Visit the Total Access Emailer page for more information on the new features or ordering information.

Receiving the New Version

Customers on Premium Support Contracts will receive a free update for their version when it is available. Existing customers will be able to purchase an upgrade at a discounted price.

Microsoft Access Could Not Lock File (Error 3050): Cannot Open Database Error

Posted on by

Microsoft confirmed the Microsoft Office security update released on Tuesday (December 14, 2021) causes Microsoft Access databases on shared drives to be locked after users exit the database. This prevents other users from opening the database and multiuser database sharing. Customers reported errors like: 

Could not lock file (Error 3050)
Could not use 'Admin' (related to workgroup security)
This file is in use. Enter a new name or close the file that's open in another program.

Several issues appear to be happening:

  1. The first person opening the database is successful but an exclusive lock is placed on the database preventing others from opening it.
  2. The Access lock file (*.laccdb or *.ldb for ACCDB and MDB databases respectively) is not being deleted after the last person exits the database. This makes the database seem like it’s still being used.
  3. This can also impact workgroup security files (*.mdw) that also have their *.ldb lock file.

From Microsoft:

This is due to the December 14, 2021 (Patch Tuesday) update to Office. The problem was introduced by a security fix, so it impacts all active versions of Access.

We are working on a fix, and will deliver it as quickly as possible.

The update has only updated a small percentage of users, and we are pausing automatic updates.

There will be a page added to the Fixes or workarounds for recent issues in Access (microsoft.com), which will be the place to go for updates.

These perpetual license updates introduced the problem :

  • KB 5002104 for Office 2013
  • KB 5002099 for Office 2016
  • Office 2019 Version 1808, build 10381.20020
  • Office LTSC 2021 Version 2108, build 14332.20204

For Microsoft 365 subscribers:

  • Current Channel Version 2111, build 14701.20248
  • Monthly Enterprise Channel Version 2110, build 14527.20340
  • Monthly Enterprise Channel Version 2109, build 14430.20380
  • Semi-Annual Enterprise Channel (Preview) Version 2108, build 14326.20692
  • Semi-Annual Enterprise Channel Version 2102, build 13801.21086
  • Semi-Annual Enterprise Channel Version 2008, build 13127.21842

If you have one of these builds, the only solution is to move back to an earlier build in the channel.

Microsoft published this new page with the latest information on this issue Error in Access when opening a database on a network file share

Rolling Back to an Earlier Version

These are Microsoft support pages for reverting to a prior update depending on your Office license:

FMS Suggestion

This problem is even in the Semi-Annual Channel which is never supposed to include such poorly tested changes.

To avoid such problems, disable automatic updates. While this is a drastic step, Microsoft repeated failed to release stable updates thereby causing more problems than they fix.

Disable Microsoft Office Updates
Disable Updates for Microsoft Office

Error: “The operating system is not presently configured to run this application” with Access Database Engine (DAO.DBEngine)

Microsoft Office Update Version 2107 (Build 14228.20204) Breaks Applications using the Access Database Engine (ACE)

Background

Last week on Tuesday July 27th, Microsoft Office released version 2107 (Build 14228.20204) to Current Channel customers. It updates the Access Database Engine (ACE) ACEDAO.dll that supports connections to Access databases.

From Access, Account, next to the About Access button is your Version, Build and Channel

Problem

Unfortunately, this broke applications outside of Office such as Visual Studio and other programming platforms that rely on ACE to open Access databases. Programs include Microsoft programs such as PowerBI, SQL Server Management Assistant (SSMA), in addition to programs from other organizations that support Access databases. Errors like this appear:

The operating system is not presently configured to run this application

The error can be triggered in Visual Studio .NET with a single line of code that initializes the Access database engine: dbe = New DAO.DBEngine

The error occurs before opening any database because the core database engine fails. Even worse, having the code in a Try..Catch block doesn’t trigger the catch. It stays in an infinite loop requiring the need to close the application from the Windows Task Manager. Ugh!

Impacts Total Access Admin and Total Visual Agent

Unfortunately, this bug impacts our Total Access Admin and Total Visual Agent programs.

Total Access Admin lets you monitor who’s connecting and disconnecting from Access databases across your network.

Our database administrator program, Total Visual Agent, automates Microsoft Access database tasks like nightly compacts.

They include EXE and DLL programs that run outside of Access and rely on ACE to support your databases. They may fail if Office/Access 365 is installed on the machine with Current Channel and ACE was updated.

This Happened Before

This is particularly disappointing because the same problem occurred in September 2020 when Office released version 2008 (Build 13127.20296). It was fixed when version 2009 (Build 13231.20262) was released.

See this Microsoft Support page for more information on that experience.

Solutions

Unfortunately, there isn’t a solution once this Office update is installed on a PC other than going back to a prior version. Visit Microsoft’s pages for instructions:

On the update history page, you can see the prior versions. Reverting back to the last Monthly Enterprise Channel version 2105 (Build 14026.20334) from July 13, 2021 works.

Change Your Update Channel

From experience, we can attest that using the Current Channel causes too much disruption. To eliminate the chance of this happening again on your PCs, you can turn off all updates, then manually update when you want:

From Access, Account, click the Update Options button and choose Disable Updates

The downside is this may leave your PC vulnerable to security problems that the updates address. It also prevents bug fixes and new features Microsoft adds to Office 365 over time. You’ll need to remember to come here and click Update Now periodically.

A less drastic change is switching your Current Channel to Monthly Enterprise or Semi Annual Channel. Visit our page How to Change the Update Channels for Microsoft 365 Apps for options and detailed steps.

Microsoft’s Expected Fix

Microsoft informed us a fix is in the Office Update scheduled for next week on Tuesday, August 10, 2021. For more information, visit Microsoft’s support page Error: “The operating system is not presently configured to run this application” when when trying to use the Access Database Engine DAO API from a non-Microsoft Office application.

Note that this is for the Current Channel, so if you changed to a different channel you won’t get this automatically.

Breaking ACE out of the Bubble!

Posted on by

An important announcement from the Microsoft Access team addresses the problems with connecting to Access ACCDB databases from other programs.

The ACCDB database format was introduced with Access 2007 and offered a new Access Database Engine (ACE) for external programs to connect to it. Connecting to the earlier MDB database format was never an issue because that requires Data Access Object (DAO) which is part of Windows.

Connecting to Microsoft Access Databases Outside of Access

ACE was available when Access 2007 and 2010 were installed. However, later Access versions sandboxed ACE so only Office could use it. It prevented other programs, including Microsoft programs such as PowerBI and the SQL Sever Migration Assistant (SSMA), from using it to support ACCDB databases.

The solution was to separately install the ACE Redistributable which provided ACE OLEDB (Microsoft.ACE.OLEDB.16.0, or Microsoft.ACE.OLEDB.12.0). That was a hassle and complicated because

  • Not every user had permissions to install it
  • Installations were 32 or 64-bit specific
  • Even if it were installed, it could be out-of-sync with the Access version that is installed.

This was especially frustrating because when Access is installed on the machine, it includes ACE but simply didn’t allow other programs to use it. And because Access/Office 365 was constantly being updated, its version of ACE may support features that the redistributable didn’t, creating conflicts.

ACE is Now Available with Access

With this Microsoft announcement, ACE is now exposed and available for external programs to use it.

If you have Office 365, or click-to-run versions of Access 2016/2019 Consumer installed, you no longer need to install ACE to support external programs.

This change enables previously unsupported scenarios, including Microsoft programs, to connect to Access ACCDB databases without installing ACE. It eliminates incompatibility issues between different versions of ACE. It also helps our programs Total Access Admin, Total Access Startup, and Total Visual Agent connect to Access ACCDB databases directly.
