Built-in microsoft exchange mail on the iPhone has its shortfalls: searching is slow, attachments must be redownloaded when forwarded, and mail can be slow when syncing. Webmail++ solves all of these by acting like a native outlook client. Its fast and works greats.
I bet many users use this app for outlook web access. One thing that would be great is if it formatted the desktop outlook web access page to a more mobile iPhone view.. Mainly just for searching my entire inbox. That would make this app perfect.
When updating I had to delete the app and redownload in order to use it without crashing.
