What is the cloud drive storage capacity?

• The cloud drive for a personal mailbox has a default capacity of 2 GB and supports single file uploads of up to 2 GB.

• An upload fails if the file size exceeds the available cloud drive space.

Uploading large attachments uses your cloud drive storage. Ensure that you have enough available space before you upload a large attachment. Regular attachments can be up to 50 MB and use your mailbox storage, not your cloud drive storage.
