I had not seen anything particularly meaningful on the server through which I normally run the MMC. When I logged onto the other DAG member, though, I noticed right off it was sluggish. Event Viewer was largely unresponsive and I saw that Microsoft.Exchange.RpcClientAccess.Service.exe was hogging all the CPU, which brought me to http://support.microsoft.com/kb/2854376. After rebooting that server, it generated some errors about not being able to mount the (secondary) public folder database (although it showed mounted via the MMC). I rebooted the other server as well and it seems to have had some impact. I am not sure why we didn't have any complaints about performance from that server, but it appears at this point to have been the source of the issue. The impacts of this were pretty odd, in my estimation. I had initially (wrongly) assumed that since you could manually navigate the public folder hierarchy and everything showed mounted in the MMC, that it wasn't really an Exchange problem.
As always, thanks for your response, Michael. I haven't been advised that it has solved all the reported issues, but if I am wrong I will do more digging and may come back for help.

From: [email protected] [mailto:[email protected]] On Behalf Of Mayo, Bill Sent: Tuesday, June 24, 2014 10:27 AM To: [email protected] Subject: [Exchange] Outlook forgetting public folder shortcuts We had a significant event last week and many servers lost power, including some of our Exchange servers. Everything came back up and things were normalized. Since that time, though, we have a large population of users that are complaining about Outlook forgetting shortcuts to public folders (legacy calendars that have not been moved to shared mailboxes). The internet suggests this is a common problem and the solution is generally to use "/resetnavpane" and/or delete the XML file. Our folks have tried that to no avail, as well as a number of things such as rebuilding the profile from scratch, disabling plug-ins, safe mode, and even reinstalling Office. What this amounts to is that the public folder doesn't show in the list when viewing calendars and taking action to make it reappear is lost when Outlook is closed and restarted. The problem is similar to the one indicated in KB 2417084, except that OWA isn't involved here. We have been on Exchange 2010 for quite a while and nobody had this issue prior to the outage, so it surely seems related. Relevant details: * Exchange 2010 SP-2 RU-6 * Outlook 2010 in cached mode on Windows 7 * 2 CAS servers in NLB * 2 mailbox servers in DAG * Mailbox databases are running on "primary" server and public folder setting is pointing to PF database on same server If anybody has any insight, it would be greatly appreciated.
