Hello,

I wrote an Outlook Add-In for Ol9 and it normally works fine with
Outlook2000/XP/2003.
I use Redemption and AddInMon. Therefore I'm not using
IDTExtensibility2.
I'm trapping Explorer_Close Event and On_disconnection for releasing
objects (and I really release all objects). I do not use CreateObject
because of problems with script stoppers.

But in some cases the add-in causes troubles. Some people using the
add-in have the Resiliency problem with the well-known error message by
disabling the add-in. Some people are getting the "Microsoft Outlook
encountered a problem and..." message after closing Outlook. Although
error messages the functionality of the add-in always works fine.
I commented out error handling and in most cases nothing changed. No
error message or crash during Outlook sessions. In some cases the
problems were saved (and that's really strange).

I tested a lot, but I didn't get these errors. And I was testing many
Outlook versions with different operating systems and virus scanners.

I know the ItemsCB example. But because of using AddInMon the code is
different. And I'm not using classes like it's in ItemsCB. But I
don't think that can cause the problems.

Now I'm desperate, because the add-in is working fine in some cases
and it's causing these errors in other cases.

Here is a part of my code: (I hope it's not too much!)

Maybe someone can help me?

Christoph, one thing that has bitten me in the butt before is not
catching my exceptions. If an exception is thrown and it is not caught,
Outlook will try to disable your add-in.

Maybe someone can help me?

Rog,
Thank you for your answer. But I don't know what you're meaning by
catching an exception.

I write my COM-addins in C#. So for example
If in the Connect class you had the OnStartupComplete method
make sure you put
try
{

}
catch(System.Exception ex)
{
//logging here
}

in the body of the method. I notice in your
"AddinInstance_OnConnection" method you do a lot of processing which of
course means things can go wrong. If an exception is thrown and it is
not caught Outlook will try to disable your addin.

Christoph,

The code you attached is concerned with startup and shutdown, and if you
were having problems with Outlook remaining in memory then it would make
sense to focus on how objects get released. But if your add-in is getting
disabled that's probably related to something that it is doing with an
object, and if it doesn't repro for you it may just be that you aren't
testing a particular action on some object. If you can't figure out what the
users are doing differently I suggest adding detailed logging to your app so
that its operations and errors to a text file that the user can send you.
That might seem like extra work but it can save many hours of guessing and
wondering.

the comment from Rog - "catching exceptions" means handling errors. If
your code generates errors that it doesn't handle those errors/exceptions
are passed to Outlook, and if it doesn't like it then it will disable your
add-in or raise an error message itself

Hello,

I wrote an Outlook Add-In for Ol9 and it normally works fine with
Outlook2000/XP/2003.
I use Redemption and AddInMon. Therefore I'm not using
IDTExtensibility2.
I'm trapping Explorer_Close Event and On_disconnection for releasing
objects (and I really release all objects). I do not use CreateObject
because of problems with script stoppers.

But in some cases the add-in causes troubles. Some people using the
add-in have the Resiliency problem with the well-known error message by
disabling the add-in. Some people are getting the "Microsoft Outlook
encountered a problem and..." message after closing Outlook. Although
error messages the functionality of the add-in always works fine.
I commented out error handling and in most cases nothing changed. No
error message or crash during Outlook sessions. In some cases the
problems were saved (and that's really strange).

I tested a lot, but I didn't get these errors. And I was testing many
Outlook versions with different operating systems and virus scanners.

I know the ItemsCB example. But because of using AddInMon the code is
different. And I'm not using classes like it's in ItemsCB. But I
don't think that can cause the problems.

Now I'm desperate, because the add-in is working fine in some cases
and it's causing these errors in other cases.

Here is a part of my code: (I hope it's not too much!)

Maybe someone can help me?

I think I have solved one thing causing the error.

In many functions I'm getting different folders.
For Example:
....
'DB.OlApp is a global Object, I'm setting at On_Connection.
....

Dim oNameSpace As outlook.NameSpace
Dim oPersFolder As outlook.MAPIFolder

Set oNameSpace = DB.OlApp.GetNamespace("MAPI")
Set oPersFolder = oNameSpace.GetDefaultFolder(olFolderContacts).Pare nt
....
Set oPersFolder = Nothing
Set oNameSpace = Nothing


Now I'm getting my folders without an own namespace variable

Dim oPersFolder As outlook.MAPIFolder

Set oPersFolder =
DB.OlApp.GetNamespace("MAPI").GetDefaultFolder(olF olderContacts).Parent
....
Set oPersFolder = Nothing

So I think the Script Stopper problem has also something to do with the
namespace object, not only with the application object.


Would it be a problem to do the same with the namespace object as I'm
doing it with the application object?
At On_Connection I'm setting a global namespace variable.
Then I'm always using the same global namespace object.

Like...

DB.olNameSpace would then be the global namespace object.
And I'm always using that object.

Dim oPersFolder As outlook.MAPIFolder
Set oPersFolder =
DB.olNameSpace.GetDefaultFolder(olFolderContacts). Parent

Is this the best solution or should I leave it like that?
Set oPersFolder =
DB.OlApp.GetNamespace("MAPI").GetDefaultFolder(olF olderContacts).Parent

It is more efficient to declare the namespace variable once at a module or
global level and keep a reference to it, but how you handle that is not
going to affect whether or not your add-in gets disabled.
