Hi @Michael Malakhov ,

Frequent Office crashes and loss of unsaved data are usually caused by add-ins, corrupted Office components, profile issues, or system-level conflicts (e.g., drivers or security software). The fact that Outlook sometimes won’t relaunch until a reboot also suggests a stuck process or external interference.

I recommend following the steps below:

Review the Microsoft guidance linked below and apply the troubleshooting steps:
- https://learn.microsoft.com/en-us/troubleshoot/exchange/outlook-issues/crash-issues
- https://support.microsoft.com/en-us/office/outlook-crashes-or-stops-responding-when-used-with-office-365-bd61bbce-36a5-44d8-a521-9440e5418337
Start Outlook in Safe Mode (Windows key + R → outlook /safe) to check for add-in-related issues. If the issue does not occur, you can re-enable add-ins one by one to identify and disable the problematic one.
Perform an Online Repair of Office.
- https://support.microsoft.com/en-us/office/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b
Create a new Outlook profile if the issue persists.
Ensure Office and Windows are fully up to date.
Update device drivers (especially graphics and network), as outdated drivers can cause instability.
Temporarily disable or review any antivirus/security software that may be interfering with Office apps.
Perform a clean boot in Windows to rule out third-party services causing conflicts.

To reduce data loss, also make sure AutoRecover/AutoSave is enabled in your Office apps.

Regards,
Burak V.

Thank you for your kind answer. Actually when I submitted my question i thought thos was direct answer to tech support, not some kinnd of forum or board. Here is my problem though. I can spend all my time here having fun asking people for suggestions, following them, and spending hours and days troubleshooting microsoft programs hoping that something will finally resolve my problems. I am not an IT specialist and have zero interest becoming one and i have stuff to do. I expect to get tech support online who will do these things for me. At the end of the day I pay for the software, am I not? Mind you I have seen these issues on my other computers when I worked for companies that did have IT guys and they still weren't able to resolve this. When I talk to tech support at microsoft they give me some lame answers like, save your files and shut down computer every night because when it goes to sleep this may happen, etc. Well, it shouldn't happen by design, should it? The fact that it happens only sometimes points to some bugs, does it not? Then what is the point for me to pay for all this? Might as well use free alternatives like most younger folks who already told microsoft to get lost. Why should i stay loyal to MS Office. Just my inertia, may be one day.

Hello

Is it just Outlook, or is it other Office apps too like Word, Excel, etc?

If it is Outlook only, hold down Win+R keys, copy and paste this into the run box and see if OUtlook can launch into Safe Mode?

outlook.exe /safe

It is everything in the Office suite. Excell will say "we have saved some files for you do you want to keep them" (or somethng like that i do not remember exact wording) but when i ask to compare those to the one that was saved by me, there are no errors. But at least other programs can be reopened. Only outlook gets stuck.
