Hi,
If your PGP Desktop license has expired, you will receive a PGP License Expiration message when you launch PGP Desktop. See the following sections for information on how an expired license affects the functionality of PGP Desktop.
PGP Desktop Email
Outgoing email messages are no longer sent encrypted.
PGP NetShare
PGP NetShare protected folders can be accessed however the protected files remain encrypted. (To view the encrypted files, manually decrypt the folders and files.)
New PGP NetShare protected folders cannot be created.
Files moved into a protected folder are not encrypted.
Keys cannot be added or removed from PGP NetShare protected folders.
PGP Virtual Disk
PGP Virtual Disks are still accessible in Read-Only mode. Read-Only allows data to be copied from a PGP Virtual Disk, however no data can be copied to a PGP Virtual Disk.
PGP Whole Disk Encryption
Any fixed disks that have been encrypted with PGP Desktop are automatically decrypted 90 days after the license expiration date.
Hope this helps you!!
