1268789 - "From" field error when calling thunderbird externally via MAPI

Status: RESOLVED INVALID

(Thunderbird :: OS Integration, defect)

Description

[jonandermonleon]

Attachment: Error SMTP Thunderbird 35.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36

Steps to reproduce:

A certain external app that uses Imapi.dll on windows, calls the default e-mail client on the system (Tested on windows 7 and windows 10) and opens thunderbird's new mail window with some fields already filled up, like the subject, the "to" addresss, some body text and some attachments.


Actual results:

Thunderbird launches, it attaches athe files, sets the "to" field and the subject correclty, BUT the "From" field does not select the default identity, showing something else instead (see attached screenshot)


Expected results:

Thunderbird should have picked up the default identity, since the workaround I'm using right now is to select my identity (i only have one) from the drop down menu on the "From" field.

The way the From field is handled has changed in TB 45 since the From field is now editable (see bug 87987). Most likely that created an incompatibility with that "certain external app".

Do you know which documented interface from Imapi.dll is used to populate the field?

Hmmm.... I could ask the developers, but I'm not sure they will give me a valid answer... what exactly should I ask for?
Thanks

Which documented interface from Imapi.dll is used to populate the field? ;-)
Or: How do they populate the From field.

Ok, they are looking into it but basically, they said they do not specify a "From" parameter when calling the library, because they count on the e-mail client to choose the default identity.
As I said, they are looking into it so I hope to have a follow up call from them at some point. (IDK if this was very helpful) :)

Ok, They were passing rubbish to imapi.dll. the bug does not exist and is not thunderbird's fault: We just noticed because until now, that passed information was ignored by thunderbird until now.
Closed bug. Thanks!

Thanks. I don't know anything about that library or the facility to call TB "externally". I'd have to find someone who does. All I know so far was already stated in comment #1.
Oh, now it's dawning on me: You mean the MAPI (https://en.wikipedia.org/wiki/MAPI) interface (which seems to be implemented in Imapi.dll).

Well, glad you could sort it out.
