= GpgOL Incompatible Addons

<<TableOfContents(2)>>

The following Outlook Addons are known to cause problems together with GpgOL.

== TITUS Message Classification

Version ?

Causes GpgOL not to decrypt / verify any content. Mails will be shown as empty and without crypto state. They will sometimes have the crypto icon in the messagelist.

=== Known Workarounds

None.

=== Technical Details

The T~I~T~U~S Addon causes the "Read" event in Outlook to be blocked and GpgOL does not receive that event. As GpgOL does the decryption in the "Read" event, decryption does not happen.

== MailStore Outlook Add-in

Version ( 9.0.3.9873 tested)

=== Known Workarounds

None.

=== Technial details

The same problem as the T~I~T~U~S Addon. We do not see the "Read" event and never get the option to decrypt / verify the mail. See: https://dev.gnupg.org/T3934


== Mimecast for Outlook

Decrypt / Verify does not work, same as with TITUS and MailStore.

=== Technical details

Not available. reported in: https://dev.gnupg.org/T4692

=== Known Workarounds

According to https://dev.gnupg.org/T4692 an update to Gpg4win-3.1.10 helped.

== PDF Converter Outlook Add-in

Version 7.1

=== Known Workarounds

None.

== Google Apps Sync

The Ggogle Apps Sync Addon makes it impossible for GpgOL to send out OpenPGP/MIME or S/MIME Mails.

=== Known Workarounds

GpgOL since Version 2.0.5 automatically detects Google Apps Sync accounts and warns the user / switches to "No-MIME" OpenPGP. This does not work with attachments.

=== Technical Details

See: https://dev.gnupg.org/T3545

== Symantec Endpoint Protection

Version - Unknown.

Signed / Encrypted mails are left blank.
