I work as a consultant for a company, their main email are inside Gmail. but they also have Office 365 tenant. My responsibility is to modify a Teams App and test it. now i got an username with companyname.onmicrosoft.com from their side. but when i tried to access the email using outlook web, i got this error:-

which means the user does not have a mailbox.  and when i tried to access Teams using the Teams web site >> i got this message:-

I click to start a new Trial >> but got this error:

so at the end can i use Teams without having a MailBox? my main work is to access the Teams apps

Thanks
