I work for an MSP and we have been getting multiple reports of Outlook crashes from a small handful of our clients, up to 5-6 times a day. The versions of outlook vary from 2010, 2013 and 2016, all experiencing the same issue. We found that the only thing in common between the users who were experiencing the issue was that they were using the Sharefile Outlook addin. We requested to remove the addin and the problem went away with it, and, upon re-installing, the issue returned. We have installed the most current version as of Nov/3 4.2.88x and the problem continues. This issue is being reported again from different businesses, and different versions of outlook. And we have absolutely confirmed that the problem stems from the addin for each user who confirmed the issue is occurring. I have read that wiping out the Appdata for sharefile post re-install would cure this problem, but it has not. Any Ideas?
