Microsoft Retreats From 1TB Limit for Auto-Expanding Archives – For Now


In November, Microsoft set a 1TB limit for Exchange Online auto-expanding archive mailboxes. Now they’ve retreated and the latest service description says nothing about a limit. The two changes in the service featured little or no customer communications and a total lack of any supporting material, like administrative controls to help manage archive mailboxes approaching the limit. While a limit has gone for now, it will be back.

Hi @Tony Redmond 

Do you have any update on this? We actually had a customer asking how would Microsoft deal with this regarding contract with customer but I think they would point the customer to OST and Product Terms in case this goes forward.

Thanks & Meery Christmas 


@Ricardo Mendes  You'll have to talk to Microsoft support. I can't help here as I don't work for Microsoft...
