The email settings can be configured in several places.
The easiest one is using appsettings.json.

The settings can also be retrieved from;
Getting settings from AbpSettings table

In debug mode, application will not send email (this is by design to avoid sending unwanted emails)
it only logs the email content in your log file.
See the NullEmailSender implementation

To send real emails even in debug mode, remove the marked code.

Important notice: The password field is encrypted, therefore you need to write the password as encrypted.
How to encrypt my email password? You can encrypt your email password with IStringEncryptionService
Inject IStringEncryptionService interface to a page model or wherever you can resolve, (you can also create simple encryption console app)

How / Where can I configure my email settings to send emails?
@talhazengin can you rebuild all the solution
@690486439 can you check if you have Volo.Abp.Commercial.SuiteTemplate.dll in your Web project output folder (for MVC non-tier).
For tier project type (or Angular): HttpApi.Host project's output directory.
See https://support.abp.io/QA/Questions/222#answer-a4f1816f-af7c-b474-dba9-39f5a00d7d20
@sean.alford as I mentioned in this post https://support.abp.io/QA/Questions/222#answer-a4f1816f-af7c-b474-dba9-39f5a00d7d20
the Suite dll must be in Web project's output folder (you sent a screenshot from your Web.Unified project)
@ididsbury, don't add the jsTree package manually, please follow my step:
Add the "@volo/identity": "~2.9.0" to the package.json in your *.Web project.

Note that, this step is needed for MVC projects.
Also, you can upgrade your existing project to the latest with ABP CLI or ABP Suite (doesn't matter)
hi @BennieMok the screenshot you show says, you have 50 questions credit and you've used 2 of them. If you have issues with your account, you can send an email to info@abp.io. this conversation is only for technical support.
@ididsbury,
Updating your existing v2.8 project (via ABP Suite) to v2.9.
then added the below migration

run the DbMigrator project to apply the new migration

and I can see it in the main menu

If you see the following error, then go to next step

Add the "@volo/identity": "~2.9.0" to the package.json in your *.Web project. (only for MVC project)

@sean.alford Volo.Abp.Commercial.SuiteTemplate.dll holds the templates of Suite and it must be located in the following directories.
Check that if you have it in the below location
For non-tier project type: Web project's output directory

For tier project type (or Angular): HttpApi.Host project's output directory

@BennieMok, fixed.
