I've problem where ADXMAPIStoreAccessor.Initialize(false) throws error.
I have found another threads in the forums related to Initialize but couldn't find any reason for it.

The MAPIStoreAccessor is not initialized, throws an exception in OutLook 2003. this problem is observed when eDoc-DM plugin is added to the outlook.

1. What could be the possible reasons for the MAPIStoreAccessor initialization problem ?
2. Actually with my plugin i don't see any problem, but problem comes only when we eDoc-DM plugin is added to the outlook ?
3. Can one plugin impact the functionality of another plugin ?
4. If the MAPIStoreAccessor initialization throws Exception, is it still possible that the stores that are properly loaded works ?
5. Is it mandatory that MAPIStoreAccessor initialization is done in AddinStartupComplete ?


sample lines of code

AddinExpress.MAPI.ADXMAPIStoreAccessor MAPIAccessor = new AddinExpress.MAPI.ADXMAPIStoreAccessor();
MAPIAccessor.Initialize(false);
transport=MAPIAccessor.GetProperty(msg,ADXMAPIPropertyTag._PR_TRANSPORT_MESSAGE_HEADERS).ToString();

Following are the error messages shown.

Hi Srinivas,

1. The cause of the issue you faced with may be various.
2. It looks like the eDoc-DM is the cause of the issue you faced with.
3. Sure!
4. Yep.
5. Nope. You can initialize the component in any event handler of your add-in. However, please note that you need to be logged in Outlook before you try to initialize it.

Did you try to pass true to the Initialize method of the MAPI Store Accessor? Does it help?

Hi Eugene,

Thanks so much for your reply.

Yes, i've tried passing true to the Initialize method of the MAPI Store Accessor, but it didn't help.

If i delete the eDoc-DM folder and unchecked the e-Doc-DM plugin then it works fine, so i'm not sure how eDoc-DM is creating the problem.

My Observation is in Outlook => data file management we can see that the file name is "not available" for the eDoc DM, the mails are stored in the server/exchange, could this be the reason Initialize failure?

Thanks,
Srinivas

Yep. You are on the right avenue. The eDoc-DM add-in adds a custom store to the profile which can't be opened by the MAPI Store Accessor component. Please try to use Redemption instead.
