Solved Sync Host error?

My machine (24H2 W11 RP 26100.4767) updated late last week and since then I've been seeing this in the Reliability History, popping up every couple hours. I did a reset in place this morning, but it does not seem to have fixed it. Any ideas campers?

Hi, I’ve had this before. Do you use Outlook? If so, Reset the Sync Host by removing it and reinstalling it.

Open PowerShell as Admin and run:


Then reinstall it:


This will reset the Mail and Calendar app, which uses InternetMail.dll

Also, you could run these for good measure:


(I have seen way too much debate on if one should use Scannow before or after RestoreHealth, all the opinions, it gets tiring. So Ima let you decide.)

Remember, always have a system image in case it’s needed, before performing any surgery on your system.

Seems to have fixed itself... I did a reset-in-place yesterday morning and noted several reoccurrences in the few hours following, but none since 2:46 yesterday afternoon, just before I had posted my query to the forum here. If it does start up again I'll try Ants' suggestion above. Fingers crossed.....
