问题
I have built a custom Outlook toolbar option using VSTO which logs an email in a database. This works fine in Windows. However, I’ve been asked if we can migrate this to the Mac for Entourage which I think is the Mac version of Outlook. Can a VSTO application be ported to the Mac? Is it possible to build custom toolbar options in Entourage?
回答1:
VSTO for Mac...no. This thread is older, but it still applies.
回答2:
No. VSTO , .NET or VBA solutions do not support the current version of Office for Mac. Supposedly next version of Office for Mac is getting a x86 version of VBA compiler.
By that time though I imagine alot of existing solutions will have been ported to Applescript, wow, what a mess.
