when I send a email of Marketing cloud in salesforce when I preview email I got a error 'Error retrieving subscriber data: [E131] We couldn't retrieve the Contact/Lead information for the Marketing Cloud. Make sure you have permission to access email opt out and try again'
pls suggest me if there is any solution for that ?
Thanks !
In my experience, the only way to achieve this globally (and without code) is to use the unsubscribe/resubscribe custom links. It sounds like you are already using this (included with the Installed Package). Even if you resubscribe the contact in Marketing Cloud, it will not share the update with the Email Opt Out field in Salesforce.
Ok, so I was able to dig this out from one of the help pages -
The "Send Marketing Cloud Email" wasn't a button but a link on a VF component available for the Contacts detail page.
Go to Contacts > Edit Layout > Visualforce Pages > ContactActions
Add this and you will be able to send single emails from the contact page.

Make sure your user has the needed permission sets for Marketing Cloud Connect applied, as well as having the Sales/Service Cloud User integrated with a Marketing Cloud user with the correct permissions. Field level security settings on the Contact/Lead object's opt out field could also have an impact on the email send.
If that doesn't help there may be a problem with the API user integration.
