Outlook.exe Cannot start Microsoft Office Outlook. Cannot open the Outlook Window

Question

Outlook.exe Cannot start Microsoft Office Outlook. Cannot open the Outlook Window

Petr Skalnik 1

We have Windows Server 2022 Standard with RDP users using their Office 365 apps on that server. Sometime they got error message: Cannot start Microsoft Office Outlook. Cannot open the Outlook Window ...

After we kill process "Microsoft Office Click-To-Run (sxs)" on server, Outlook can be run normaly. But after about one or two weeks problem repeats.

Hi @Petr Skalnik

I would like to confirm did you install different versions Office on the same PC, and do other Office Apps (like Word, Excel etc... ) have this same issue?

According to my research, this issue seems to be caused by Microsoft Office Click-to-Run High Disk Usage

everytime when I kill process Microsoft Office Click-To-Run (sxs) in task manager, they can start Outlook and can use it few days, so after some time I know if it helped. But now They called me, it hapend again. So deleting files in Spw and OfficeFileCache in users appdata didn't solve the problem. :(

now i tried to disable microsoft office click-to-run service and set it to run manually. we'll see. there will be an update about that in a few days
