Hi @Garrison Geho ,
Welcome to our forum!
Does this issue occur recently? If so, have you done any specific operations before that?
And does this issue occur with other account except Gmail account?
Considering that it may be caused by the damage of the profile/data file in the Outlook client, it is suggested that you could try to create a new profile (Control Panel>Mail>Show Profiles>add) and add the account for testing to check if there are some differences.
