Hi @Claudia Ferguson ,
Welcome to our forum!
What's the version of your Outlook? (File > Office Account > About Outlook). Please make sure you have upgraded your Outlook to the latest version.
And have you done any other operations? Such as intalling third-party programs or addins?
In addition, do other user around you encounter the same issue or does this issue occur with other machines?
As we know, there are a number of possible reasons for Outlook to freeze, such as damaged profile, third-party add-ins, etc. It's suggested that you could refer to this article ang try the steps for troubleshooting: Outlook not responding error or Outlook freezes when you open a file or send mail.
In addition, i found that there's a known issue mentioned that when opening, replying, or forwarding some emails that include complex tables, Outlook stops responding. The same table contents will also cause Word to stop responding. If this is your issue, please try to install the update from Outlook. For more information, please refer to: Outlook stops responding when viewing Uber receipt emails and some other emails with tables.
Hope the above help!
