Cannot log in to PartnerSource Business Center - get "unexpected error occurred"

(0) ShareShare

Posted on by 10

I need to access the partner source portal in order to add our assigned granule range.to a BC license. I have done this in the past via the PartnerSource Business Center (https://businesscenter.mbs.microsoft.com). But now when I try to access that site, I get the get the following error:

Our apologies...An unexpected error occurred.
In order to resolve this issue as quickly as possible, please contact support and reference error ID: 4545ff53-6b26-4f33-bc44-768dd45626f1.

I've tried this from multiple browser (Chrome & Edge), Incognito/InPrivate -- no luck, always end up with the same error.

Two questions:

1) Am I even on the right partner portal to do what I need to do? These things are changing constantly, hard to keep up.

2) If I am on the right portal, any idea (other than starting a Microsoft Support case) to get logged in?

Thanks!

-Wayne

    OK, I'll do that - but do you happen to have a link to where I can log such a ticket? When I google it, it brings me to.... you guessed it... the same site & same error :)
