How to Uninstall Microsoft Portal Solutions and Install Again

Hello Everyone,
Today i am going to share a scenario, due to some reasons if you want to reinstall Microsoft Portal on your Dynamics 365 Environment, you achieve a clean reconfiguration in couple of ways.
1. Restart provisioning2. Change configuration and retry3. Reset portal4. Uninstall all the Microsoft Portal Solutions.
So i am not going to discuss about the first three points here as everyone is familiar with it,as i have shared a screen above.
Lets discuss about the Microsoft Portal solutions uninstall, this task should be carefully done otherwise you may end up in bad situation.
Firstly you need to get to know what solutions needs to be deleted from the Dynamics 365 Solutions.Follow the blog this blog post by Jon Birnbaum https://community.dynamics.com/365/b/dynamics365portalssupport/posts/portal-troubleshooting-part-three-uninstalling-portal-solutions
You might be wondering how to construct  the fetch xml of the solutions.
Its so simple you might get it from the customization’s area of the Dynamics 365. Settings > Customizations >  Organizations service..

Construct the url by using the blog provided above or for your convenence i am showing below:
https://[orgname].crm[x].dynamics.com/api/data/v8.[x]/solutions?fetchXml=<fetch mapping=’logical’><entity name=’solution’><attribute name=’installedon’/><attribute name=’friendlyname’/><order attribute=’installedon’ descending=’true’/><link-entity name=’publisher’ to=’publisherid’><attribute name=’customizationprefix’/><filter type=”and”><filter type=”or”><condition attribute=’customizationprefix’ operator=’eq’ value=’adx’ /><condition attribute=’customizationprefix’ operator=’eq’ value=’msa’ /></filter></filter></link-entity></entity></fetch>
Place the orgname to your dynamics 365 url and paste this url on the browser and you will get the following solutions list like below.

So you can see from query, there are solutions which have been installed on 2018-10-27 with solutions names.

Carefully delete all the solutions from the Solutions area on the Dynamics 365 Customer Engagement area.

Once you have managed to delete the solutions, then go back to your Dynamics 365 Admin center:

Choose the Instance tab and look for the “Portal” Solution which may not be in the configured state.

Select the portal solution and click on the manage icon, then your portal will start provisioning.

I hope this helps
