Hi Rudy,
>>When Outlook is started in Safe mode, the issues stop.
In case there were some spam add-ins installed on Outlook client, we can check for third-party COM add-ins and to disable them, follow these steps:
- On the File tab, click the Options.
- Click Add-ins.
- Select COM Add-ins from the Manage box, and then click Go.
- Click to clear the check box for all add-ins.
- Click OK, and then restart Outlook.
Please check if issue continues.
>> When Outlook's cached mode is disabled, the issues stop.
One difference is that Outlook use local data files(.ost) under cached Exchange mode while Outlook directly access items from server under Online mode.
To help check if this issue related with data file(.ost) or personal settings, we can also
create a new profile to test the results.
Any updates, please feel free to post back.
Regards,
Perry
