SearchProtocolHost.exe Keeps crashing with Event ID 1000

I ran into an issue where the Window search service would constantly crash. The Event viewer showed the error below, and the crashdumps folder has a ton of SearchProtocolHost.exe.21580.dmp files. Faulting application name: SearchProtocolHost.exe, version: 7.0.9600.19660, time stamp: 0x5e4586a5 Faulting module name: mso20win32client.dll, version:, time stamp: 0x5e8a785b Exception code: 0x0241938e Fault offset: 0x00196a44 Faulting process id: 0x24a4 Faulting application start time: 0x01d617e35d974e4f Faulting application path: C:\windows\sysWow64\SearchProtocolHost.exe Faulting module path: C:\Program Files (x86)\Common Files\Microsoft Shared\Office16\mso20win32client.dll Report Id: b5c9d48f-83d6-11ea-80fa-000c290a7afd Faulting package full name:  Faulting package-relative application ID:  Analyzing the crash dumps pointed to MSPST32.DLL but none of the users had PSTs loaded.

Outlook Switching to Online Mode Even Though Cached Mode is Enabled

I have been dealing with an issue where a user's outlook would switch to online mode at random. The only way to resolve the issue was to log the user out of the computer and back in. Re-creating the account resolved the issue, but it came back the next day. Procmon and ProcExp didn't point to any clear causes.

This resulted in a situation where the mailboxes were fighting for who would be the primary mailbox, and who would be the secondary. Removing the permissions resolved the issue and both mailboxes worked correctly inside of Outlook.
