Review for Owl for Exchange by mihran
Rated 4 out of 5 stars
Since TB 102, I have an issue with the Unified Folders view. On start up, it opens the unified inbox and has two copies of the exchange account inbox. When I click and unclick the All Folders option, it is corrected. Next time I start the app, the same thing happens. In TB 91.12.0 this does not happen.
Otherwise, it is an excellent extension well worth the price to avoid outlook.
