Deprecating add-in for specific Outlook version

Hi,

In a few months, Microsoft will stop supporting Outlook 2010 and when this happens, I would like to stop users from using my Add In with Outlook 2010 also.

- How can I prevent my Add In from running on specific Outlook versions?

- In addition, the Add In was currently build with support for Outlook 2010. Would you recommend to update the Add In express dlls so they only support Outlook version > 2010?


Thanks,

Mark

Hello Mark,

The adxloader.dll.manifest has the minOfficeVersionSupported attribute. The value of the attribute is the Office version specified when creating the project; you can change it if required. When Office loads the loader, it compares this value with the Office version and stops or continues the load process.

If you would never deal with Office 2010, you can replace interop assemblies in the Interops folder with that from the {Add-in Express}\Redistributables\Interop Assemblies\Office 2013 and rebuild your project. This will let you use early binding to use features introduced in Office 2013; with Office 2010 interops you would need to use late binding. Also, we recommend embed the interops; this is only possible to do if you use the .NET Framework 4.x. Check Interop Files.
