Review for Owl for Exchange by Firefox user d39394
Rated 5 out of 5 stars
Worked great until about a week ago. Lost ability to access my calendar. Then upon upgrading to TB 115, I lost my added account and am unable to re-add it through the addon preferences page.
EDIT: Discovered that my issue was caused by a library issue that is installed with thunderbird. After fixing the library issue, Owl returned to functioning normally.
