GpgOL Incompatible Addons
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 TITUS 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.
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.
