Looking over the
Get-SPOTenant output of our tenant, I see the property OneDriveStorageQuota. This sets the quota for all OneDrive for Business users, no big deal. It is set to 1TB and we are fine with that.
Does this also affect Office Groups? I'm not in a position to test so I'm asking here.
I can make the logical leaps that an Office Group is a OneDrive site, therefore it would take this value, and for all intents and purposes, this is what we see when examining the Unified group via PowerShell. We're fine with 1TB personal spaces as those don't count against the pooled tenant storage and would like to enforce reasonable storage quotas on Groups when they are created.
