How to programmatically access old archived mails in Outlook in plug-in

Devendra Tewari 1

Hi All,

I have developed VSTO plug-in for outlook in C#. My outlook is configured for OST to show 30 days old mails. However when I click on “Click here to view more on Microsoft Exchange”, it shows all old mails. But even then, when I try to access using OOM model, it returns only mails present in OST, not other mails (although those mails are visible in outlook view).

I am using following code to get mail :--

MAPIFolder currentFolder = GetCurrentFolder();
Items col = currentFolder.Items;
int count = col.Count;

It is returning same count even if I already loaded older mails by click on “Click here to view more on Microsoft Exchange”. Can somebody suggest solution of it ?

Thanks
Devendra

Hi @Devendra Tewari ,
Considering your issue may be more related to development of vsto plug-in, please kindly understand we mainly focus on general issue on Outlook desktop client in Outlook forum, so I removed the Outlook tag to solve your issue better, thanks for your understanding and hope your issue would be resolved soon.

Hey Jade,

Is it right forum to ask a question ? I did not get a single answer on my last question also while in past I am use to get many answers. If it is not right forum, can you please point me to right link, where I can ask these questions.

Thanks
Dev
