Troubleshooting Persistent Reappearing Meetings in Exchange + Arctera Integration
We've been running into a really annoying issue lately in our Exchange environment, which is integrated with Arctera, and I'm hoping someone here might have seen something similar or have some insights. The problem is that some users are experiencing old or deleted calendar meetings reappearing in their Outlook calendars. They decline them, delete them properly (even emptying Deleted Items), but days or weeks later, the same meeting invite can pop back up. It's causing significant calendar clutter and confusion. Initially, we were looking into potential sync issues related specifically to the Exchange-Arctera integration, wondering if maybe updates weren't propagating correctly or if there was some conflict in how shared calendar resources are handled between the two systems. We're still investigating that angle. However, while digging deeper into the Exchange side of things, I stumbled across a pretty comprehensive article that outlines several Exchange-specific reasons why this might happen, independent of any integration. It covers things like: Lingering invites in different mail folders. Corrupt recurring meeting series. Issues with calendar delegation permissions. The Calendar Repair Assistant (CRA) potentially misbehaving. Outdated clients or mobile device sync problems. Here's the article if anyone's interested: How to Stop Exchange Server from Recreating Meetings? It has some useful steps for both end-users and admins (like PowerShell commands to check/disable CRA or repair mailboxes). My question for this group is: Has anyone using an Exchange + Arctera setup encountered this specific "ghost meeting" issue? If you did, did you find the root cause was purely within Exchange (like one of the points in the article), or did you discover an interaction or configuration nuance related to the Arctera integration that was contributing to it? We're particularly curious if certain sync settings or how delegate access is managed across both platforms might play a role. Any shared experiences or troubleshooting tips specifically within the Exchange/Arctera context would be hugely appreciated! Thanks in advance,
