I am a one-person consultancy. Since it's only me, I use Microsoft 365 Family; I do not use any organization/business license for Microsoft products. This past weekend, I had to update my email server, since my old provider (Webfaction) has been purchased by/rolled into GoDaddy. So with my son-in-law's help (he's a software programmer) we ported my email from the Webfaction server to GoDaddy; GoDaddy uses Outlook 365, so that's now how my email is set up. My email address and my domain name did not change.
Since the email switch, I have been unable to access Microsoft Teams as before on my laptop. (I am still able to use it as before on my iPhone and iPad.) Teams keeps telling me when I try to access it on my laptop that "You don't have access to the <my email address> org in Teams. Select another org, or contact your admin for more details." Also, one of my clients has included me as a Guest in one of their project Teams, and that access no longer works, either. The client has tried deleting me and adding my email address again, but with no luck in my gaining access to critical project information.
Teams will let me in if I act as if this is a "personal account," but it's not syncing with my Microsoft 365 products, and if I'm in as a "personal" account, I still can't access my client's Team as a Guest.
NOTE: Previously, I don't recall doing anything to set up my email address as an organization in Teams, but maybe I did - is that something that needs to be done?
How can I get Teams working again on my laptop computer??? Thanks for any help.
