Microsoft announced that it is doubling the size of user mailboxes in all Exchange Online and Office 365 service plans. Inbox sizes are going from 2 5GB to 50 GB.

Better yet, users won’t have to pay any more for the additional storage.

“With this increase even the most active email users don’t have to worry about mailbox size limitations-we’ve got you covered!” writes Exchange product manager Stephen Brown in a blog post. “There’s no price increase associated with this change. Our doubling of your mailbox storage is simply part of our promise to continuously deliver value to our Office 365 customers.”

He continues, “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.”

Microsoft is also increasing the size of other mailboxes. Shared mailboxes and Resources mailboxes are increasing to 10 GB, which is more than twice what they were.

Users won’t need to do anything special to get the storage increase. It will just happen automatically. Roll-out has already begun, and will continue into November.
