Can Outlook(office) Add-In impact performance of any other existing Add-Ins present RRS feed

  • Question

  • We have created Outlook Add-In using Visual Studio Outlook 2013 Add-In project template. I understand that if my Add-In is slow then it can hamper overall performance of Outlook. But, can Add-In developed by us hamper the performance of other Add-Ins which are already present inside Outlook on end user's machine?

    If yes then, how can we test or measure impact of Outlook Add-In on other Add-Ins?

    It will be really great if someone from office team can answer this.

  • Hello,

    According to Architecture of VSTO Add-ins

    If multiple VSTO Add-ins are installed for an application, each VSTO Add-in is loaded in a different application domain. This means that one VSTO Add-in that behaves incorrectly cannot cause other VSTO Add-ins to fail.

    It also helps to ensure that when the application is closed, all the VSTO Add-in assemblies are unloaded from memory. For more information about application domains, see Application Domains.

    So I think Add-ins would not hamper the performance of other Add-ins which are already installed in Outlook.
