Microsoft Office 365 - Exchange Online Mailbox Size is now 50GB Per User!
For those of you who may not already be aware, on the 29th August Microsoft announced the increase to the Primary Mailbox Size for Exchange Online / Office 365 Exchange Online Customers. This comes weeks after the recent increase to SkyDrive Pro Storage allocation.
The size of user mailboxes in all Exchange Online and Office 365 service plans is doubling. Beginning today, the current 25 GB of mailbox storage is increasing to 50 GB.
This increase to a 50 GB mailbox per user benefits Exchange Online and Office 365 service plans, including: Exchange Online Plan 1, Office 365 Small Business, Midsize Business, Enterprise E1, Government G1, and Education A1. If you have one of our premium service plans (Exchange Online Plan 2, Office 365 Enterprise E3 and E4, Government G3 and G4, Education A3 and A4), you already enjoy unlimited email storage through your personal archive, but now your default primary mailbox size is increasing to 50 GB. Kiosk user mailboxes are doubling in size, too-from 1 GB to 2 GB.
