“Login failed” message received sending email

Recently, some users have been receiving a “Login failed” message when they send email from within Acctivate.  We believe this is due to some recent updates for Microsoft’s Office365 service.  Microsoft has been pushing companies to upgrade from the older Office365 Small Business plans.  As user accounts are upgraded, Office 365 appears to be blocking the sending of email through third party applications.  We believe this may be caused by some changes in Office 365 security settings.

Currently, we aren’t aware of a solution to resolve the “Login failed” messages.  As we continue to work with our customers and their IT/Email Support personnel, we hope to be able to share a resolution with others that may be experiencing this issue.

Here are a few possible workarounds to allow users to send email within Acctivate.

Try disabling Cached Microsoft Exchange Mode

This mode is enabled by default when creating a new Outlook profile and allows a outlook profile to be sync’d from the Microsoft Exchange server to the local machine. When Outlook starts up, it will check all the folders to ensure all changes are pushed and received. The idea is if you move machines often, then your profile will always be up to date and will not need to “redownload” the outlook profile upon startup. Some downsides mentioned here below and should be considered by anyone whom manages the Exchange server environment and their users: http://superuser.com/questions/62156/are-there-disadvantages-to-using-outlooks-cached-exchange-mode

To Disable Cached Microsoft Exchange Mode, open Outlook and go to File > Account Settings  > Account settings

account-settings-outlook

 

click on the outlook profile > Data Files Tab > Advanced. You should see “Cached Exchange Mode Settings” and it might be enabled by default. Uncheck this option and then restart Outlook.

Once Outlook has reopened, attempt to send an email from Acctivate.

Consider using SMTP instead of Microsoft Mail (MAPI) protocol

Acctivate can be configured to connect to an email server using SMTP instead of MAPI, which is usually a more forgiving and is the preferred method  in regard to connecting and sending email.  Learn more about the differences between SMTP and Microsoft Mail, here.  You can also read more about configuring Acctivate to use SMTP here.

Verify Outlook is installed as a 32bit application

Outlook 2016 can be installed as a 32bit application or a 64 bit application.  Microsoft still recommends Outlook being installed as a 32bit application at this time.  During the installation of Outlook, users are typically prompted to use 32bit if they require third party applications, such as Acctivate, to connect and send email.  Acctivate also HIGHLY recommends you install Outlook as a 32bit application.  You can read more about sending email in Acctivate when Outlook is installed as a 64bit application here.

Review Office 365 Security Settings

You may review this Microsoft article regarding modifying our mailbox permissions, which will allow third party applications to send email utilizing a different email account.

Verify your current connection information in Acctivate

As user accounts are upgraded, we believe some user accounts may actually be “recreated”.  Verify Acctivate is currently configured properly to connect to the user’s Office 365 account.  This is our guide for connecting Acctivate to an Office 365 account.
