Im not receiving a verification code when trying to login.

Question

I have a Office 365 mail account called "******@cmmm.se" and when I try to login i'm not receiving the verification code on my phone.

I recently got a new phone, maybe that has something to do with it.

You can restore from backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake. https://support.microsoft.com/en-us/account-billing/back-up-and-recover-account-credentials-in-the-authenticator-app-bb939936-7a8d-4e88-bc43-49bc1a700a40

For a work / school account an account admin can reset the authentication device here,

Without a backup to restore from the only option is to work with each of the service provider's account recovery methods. The authenticator app is nothing more than a code generator. The two factor is turned on or off at the service provider end.

Check your block/unblock users and unblock if it is blocked. Please note that if your name is listed as a blocked user, you will not receive a text code. It happens for some users by the system due to device or location changes.
