I recently migrated a MailEnable instllation from a Win2008r2 machine to Win2016.
Everything has gone smoothly and works, including the built-in WebMail app/web.
But a custom app of mine which uses MailEnableStore.dll now crashes when calling any StoreItem_GetProperty()
I get an ''Arithmetic operation resulted in an overflow.' error.
Both my legacy and new server are running the same version of MailEnable (10.15) and my custom software is unchanged. It can successfully perform StoreFolder_open() and StoreFolder_FindFirstItem() but fails when trying to access a message's properties.
Any clues, please.
