Unable to change primary SMTP of a group
I have a 365 group linked to Teams, with the primary SMTP address of mailto:HumanResources@(domain) I have been trying to change that by promoting an alias (PTmailto:onTeams@(domain)) to be the new primary.
Every time I do this, it reverts to the original HumanResources address.
A bit of searching suggested I try checking the primary address with the Get-UnifiedGroup powershell command, then setting it with Set-UnifiedGroup. Unfortunately, Get-UnifiedGroup shows that the primary SMTP is the desired PTonTeams address. It just isn't showing as such on the Exchange admin page.
If I look up that same group in Azure, it also shows that it has the original address set as Primary SMTP.
Can anyone shed some light on what might be going on and help me change this email address?
Thank you!

Thanks. The issue mysteriously fixed itself overnight (after a week of trying) but will remember for next time!
What you are describing sound like an issue with the dual-write process between Exchange Online and Entra, unfortunately we have no way to troubleshoot such issues, afaik. You can try removing/re-adding the alias to "trick" it, and if that doesn't help, best open a support case.
