Generating and sharing metadata for indexing synchronized content items. A server generates metadata for indexing synchronized content items and manages sharing of the metadata with client devices in accordance with user preferences that may be embodied in metadata generation and sharing management rules. For example, a content item stored at the server has been designated to be synchronized across at least a first client. The server generates metadata for indexing the content item and sends the metadata to at least a second client.

Generating and sharing metadata for indexing synchronized content items

Participant identifiers, or display names, for participants in an electronic communication can be selected such that each participant's display name is unique relative within a defined set of 'relevant' participants, such as all participants in an electronic communication exchange or all contacts in a contacts list maintained for a specific user. Selection of display names can be optimized to provide a unique display name for each participant using a reduced or minimized number of characters.

Embodiments of the invention generate and share metadata for indexing synchronized content items. A server generates metadata for indexing synchronized content items and manages sharing of the metadata with client devices in accordance with user preferences that may be embodied in metadata generation and sharing management rules. For example, a content item stored at the server has been designated to be synchronized across at least a first client. The server generates metadata for indexing the content item and sends the metadata to at least a second client.

Shareable content item links with use restrictions. In one embodiment, for example, a method comprises: receiving, from a client computing device used by an authenticated link submitter, a first request to access a server-stored content item at a shareable link; wherein the link submitter is authenticated according to a first authentication factor; responsive to receiving the first request, prompting the link submitter to enter/submit a second authentication factor; and providing access to the server-stored content item at the shareable link responsive to receiving the second authentication factor from the link submitter.

Sharable content item links with use restrictions

Shareable content items links with use restrictions. In one embodiment, for example, a method comprises: receiving, from a client computing device used by a link submitter, a request to access a server-stored content item at a sharable link; denying the access requested by the link submitter based on one or more use restrictions associated with the shareable link; prompting the link submitter to request approval to access to the server-stored content item at the shareable link; responsive to receiving approval for the link submitter to access the server-stored content item at the shareable link, modifying the use restrictions associated with the shareable link to allow the link submitter to access the server-stored content item at the shareable link.

A system and method providing sharable content item links with link sharer specified use restrictions. The method includes: receiving, from a device used by a link sharer, a request to share a server-stored content item as a sharable link; causing a user interface to be presented at the device that allows the link sharer to specify one or more restrictions on how the sharable link is used to access to the content item; receiving, through the user interface presented at the device, a specification of at least one of the restrictions; receiving, from a device used by a link submitter, a request to access the content item at the sharable link; determining whether the at least one restriction prevents the link submitter from the requested access; and granting the requested access only after determining that the at least one restriction does not prevent the link submitter from the requested access.
