Dynamics GP Workflows Not Working with a Gmail Account

Working-Around It

GP’s 15-character password limit will cause issues because many Gmail users will secure their account by using an auto-generated “App Password.” In this case the "App Password" will generate a 16-character password, which exceeds the limit for the SMTP password of 15 characters.

Setting Up Gmail

Take these steps to get your Gmail through Dynamics GP to work:

1. Configure Gmail to have a password with 15 or fewer characters. To do this, click on your picture in the top right corner of Gmail, and then choose My Account.
2. Disable 2-step Verification within your Gmail account settings. In the image above, this is found under Signing in to Google.
3. Set “Allow less secure apps” to be “On” within your Gmail account as well. You can find this in the same section of Sign-in & Security, under Apps with account access.

This should resolve the issue. If you have any questions reach out to me and lets see if I can help
