Quantum Project Manager Mass Emailing Changes
(Last updated 5/4/2022)

Effective May 30, 2022, Google is implementing changes to drop support of the option to "allow less secure apps" to send emails via the Gmail SMTP server. This option is what allows third party programs like the Quantum Project Manager to send emails directly through the Google SMTP server using basic authentication (user id and password). If you have this option enabled on your Gmail account, you should have been notified by Google recently about this change. Consequently, effective 5/30/2022, you will no longer be able to use and your gmail account in the Quantum Project Manager email options settings.

This only affects the Quantum Project Manager mass emailing option (invitation to bid), Letters/Emails from the main menu, or any communication document where you send email directly via the CC/Email tab and the send via email button. These features use the email options settings and send mail directly to the SMTP server specified. This change DOES NOT affect anyone creating PDF/RTF/Word files and then emailing them through the Microsoft Outlook Windows client application or other email programs.

If you are affected by this change, instead of using the Gmail SMTP server, you can use any email server that supports SMTP and relay. If you don't have your own email server, starting with Quantum Project Manager version version 20.0a, you can now use the Office 365 SMTP server using TLS. Just use your Office 365, Exchange Online or email address, user name and password. Make sure your settings for your email account are set to allow SMTP Authentication. On the email options screen in the Quantum Project Manager, use the new connection type of TLS, mail server name, and port 587. If you don't have an Office 365, Exchange Online or account, you can signup for free at or you can get Exchange Online and/or Microsoft 365 from Microsoft. You can also get professional email associated with your own domain name and/or Microsoft 365 from GoDaddy at You will need to make sure that SMTP Authentication is enabled for your account. There are limits with sending email through the Office 365 SMTP server. If you are sending a lot of mass emails to a lot of recipients, you might consider using third-party email service providers that support SMTP like Twilio Sendgrid.
