Unable to modidy Group addresses via PowerShell

[VasilMichev]

There seems to be some ongoing issue with the Set-UnifiedGroup and the -PrimarySmtpAddress/-EmailAddresses parameters, meaning we are unable to update the SMTP addresses for groups. No matter how many variations I try, I end up getting:

"We failed to update the unified group. Please try again later."

I know it's not just me, as this issue was reported over at the TechNet forums. Here's the original thread: https://social.technet.microsoft.com/Forums/msonline/en-US/d238a421-6db6-441a-ae43-496f5b78a1af/unab...
