GPGOL crashes on Windows 10 / Outlook 2016
Closed, ResolvedPublic

Description

GPGOL is not usable for me. Each try to send a signed message ends up in a crash.

The Windows event log shows the following entries:

Add-in execution error. Outlook crashed during the 'AfterWrite' callback of the 'ItemEvents_10' interface while calling into the 'GpgOL - The GnuPG Outlook Plugin' add-in.
Add-in execution error. Outlook crashed during the 'Send' callback of the 'ItemEvents_10' interface while calling into the 'GpgOL - The GnuPG Outlook Plugin' add-in.

This is reproducible and renders the plugin unusable. FYI: Kleopatra and all other tools work perfectly fine.

GPG4Win version: 3.0.1

Strange, do you have any other addons? Maybe some interference.

Could you please enable the GpgOL log (Described in https://www.gpg4win.org/doc/en/gpg4win-compendium_29.html ) and Post the result here.

Thanks!

Here you are

The only other plugin I'm running is the Google Sync plugin to synchronize my mails from GoogleApps.

Outlook never seizes to surprise me. Not finding the HTMLBody property (its usually also there for Plain Text mails) is surprising and resulted in a bug in GpgOL that might have lead to a crash.

If you have the time it would be great if you could replace your gpgol.dll with the beta10 uploaded to: https://files.gpg4win.org/Beta/gpgol/ and try again? This version contains a fix for handling the case that HTMLBody property is not found.

Thanks in advance.

Done. Now Outlook does not crash anymore, but GPGOL emits an error dialog:

Here's the corresponding log:

Thanks.
So GpgOL can neither figure out the sender's address nor the recpients. It then fails to do crypto because kleo does not know who it should encrypt to.

I'm installing Google App Sync myself now to test with a gmail account. I need to reproduce such a state to do some introspection where the sender / recipients are available in this case.

I'm using the same Outlook 16.0.0.8625 on Windows 10 with a Gmail Account over IMAP and I have the Google Apps Sync plugin enabled. Everything works fine :-(
What is your senders account? Is that also GMail or something different. In the log I only see that the recipient is GMail.

Do you have your account configured through the google apps sync thingy or just as an imap account?

I can't seem to run the G Sync setup tools as they immediately crash for me, so I don't really know what this is supposed to do. :-/

I use the Google Sync plugin to connect with our company Google Apps account. It also synchronizes the calendar entries as well as all other special stuff.
I'm quite sure that the standard POP/IMAP mechanisms in Outlook might not deliver the sender's address (however the receipient's address is contained in the logs above - my googlemail.com address).

Although the sender's field in the Outlook send email dialog shows my sender address correctly.
The G Suite plugin installs a Windows MAPI provider that is the one showing up under email profiles in the control panel.

Ok I'm pretty sure that the Google MAPI provider is the problem because it likely has some different Data structures.
For Sender we already have three fallbacks as it's saved differently for Exchange over MAPI, Exchange Active Sync and IMAP. So we probably need another fallback for Google Sync >.<

aheinecke raised the priority of this task from Normal to High.Nov 28 2017, 8:02 AM

I put it at high priority because i want to check / fix this before the next release.

aheinecke added a project: Duplicate.

Oops I just noticed that this was already reported in T3424 which I somehow overlooked. Let's handle it there as there are more subscribers in that report and it's older.

Thanks for the efforts. I will subscribe there to be up to date :-)
