Having issue with Teams and unable to reach microsoft marketplace team

Dear moderators and actual msfs marketplace partners,

First please take my apologies for posting here topic about marketplace issues, I know it’s a dev forum but I’m a little desperate because I can’t reach the marketplace team directly.

For some unknown reason I having troubles with logging in into my Teams account, where I’ve been chatting with marketplace team for the last 2 and half years.
I tried to contact the team writing to the 3yo email address (msfsmp) then I also forward my letter to the email address that currently listed on marketplace partner program page (msfsim@microsoft.com), both letter with no replies at this time. Also I was trying to contact with Rachel L. but his email is down.
The support (help icon ?) option in partner center is working only as faq, there is no more contact form.
I didn’t not receive any email or notifications letters about like Teams channel changed or something. Maybe I guess something has changed in communication methods with partners, but I didn’t know about it.

Hope someone could share useful working email to contact Mabel or Steve directly to understood what’s going on.

Best Wishes,
Tom.

Nothing has changed on my end as far as communications go. What exactly is the issue that you are running into? Redirect loop, getting logged out of your account immediately after signing in, etc? Also, for how long has the issue been there?

I’ve talked with some other developers who have had issues with Teams and not being able to log in in the past, but usually it just solved itself after a few days.

Thank you for your attention Sir,

The problem occurs when I trying to login to Teams channel as guest account, after putting in credentials I’m encountering with following error “Your account has been locked. Contact your support person to unlock it, then try again.”.

I have encountering with this error since October 23 at every login attempt.
Google says I need to contact support person to solve it, I guess it means the channel admin.
Also my personal Teams account is working fine and other services on same microsoft account like outlook and partner center logging in fine too as well.

Sent you a PM.
