Hi ,
Before going further, please make sure you have upgraded your Outlook to the latest version.
What's the type of your account? POP, IMAP or Exchange? In order to confirm if the issue is related to your email account, it is suggested for you to use other email accounts and see if there is any difference.>> Outlook is randomly crashing when navigating around the inbox, not particularly frequently and with no identifiable replication steps.
Can this problem be reproduced when using other programs in Microsoft office such as Word?>> Report.wer file shows wwlib.dll as the faulting module
According to my research, the wwlib.dll file is one of the important components of Microsoft Office, please try the following suggestions to troubleshoot:
- There could be some add-ins in your Outlook client that cause this issue, so it is suggested to start your Outlook in safe mode (Press Win + R, type “outlook /safe”, press Enter.) and see if the issue continues.
- It is suggested to replace your wwlib.dll file with other wwlib.dll files of Outlook client which can be used normally and see if there is any difference.
File location C:\Program Files\Microsoft Office\Office16 (Notice: Please backup your files to avoid loss.) - If the problem continues, please try to repair your Office.
Hope this can be helpful.
