Citrix Files for Outlook


Citrix Files for Outlook allows you to bypass file size restrictions and add security to your attachments or emails by sending them through Citrix Files. You can provide a secure file upload request for co-workers, customers, and partners directly in your email.

Be notified whenever someone accesses a file or sends you a file so you are always aware of what is going and can take action. You can also set different security and access levels on a file-by-file basis for greater control.
