Dear Community!
Short version:
Our Subscription Center is online but throwing an error when the email gets submitted (with submit button) to unsubscribe.
Fiddler trace "Fiddler shows a SubmissionStatus=ContactIdIsUnknown"
Long version:
A few days ago we installed a partner portal and our default marketing site domain(org2bd3a164.s01.dyn365mktg.com) got overwritten with our partner portal URL(companyname.microsoftcrmportals.com).
From that point our Default Subscription center wasn't accessible anymore (because the updated URL pointed to nowhere).
I managed to do two things:
1) Redirect the Subscription Form-Request to a sub-site of our partnerportal(companyname.microsoftcrmportals.com/subscriptioncenter).
2) Remap the old URL with the new one and show our Subscription Center on a clean place (companyname.microsoftcrmportals.com/unsubscribe).
Add1: I would need to design a Portal Form and mimic the functionality of the Subscription Center (hence it's just a redirect to our partner portal)
Add2: It's throwing an error on "Submit". Fiddler trace "Fiddler shows a SubmissionStatus=ContactIdIsUnknown"
We actually do not have custom code and the subscription center and also the marketing form are default. I have no idea why this super basic functionality does not work. We just want to set "donotsendbulkemails" flag to the contact with the corresponding email. (Default behaviour & usecase of Subscription Center)
Please help me - we wanted to go live yesterday with our newsletter.
Kind regards,
Preblauer
