Outlook startup problem has been successfully solved by Microsoft, and users will no longer be troubled by slowness

Microsoft recently released a support document, announcing that it has successfully solved the problem of slow startup of Outlook in Microsoft 365 and even occasional complete freezes

According to Microsoft's official announcement, Microsoft admitted in June this year This issue exists and Beta channel users have been invited to test it. It plans to push a fix patch to Microsoft 365 users in the current channel in November this year

In a report in June this year, Microsoft pointed out that the root cause of this BUG is that Outlook synchronizes the entire offline data during the startup process. file (.ost), which causes Outlook to start slowly and even freeze occasionally in certain usage scenarios such as airplane mode.

According to my understanding, there are currently two temporary solutions:

One method is:

Rewrite it as: Open the Registry Editor

Enter the path of HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Options\Calendar

Select RestUpdatesForCalendar and set its value to 1

Restart the computer

Another way is:

Open Outlook account settings

2. Click twice to set storage settings

Enter "More Settings" and "Advanced" options. You can click the relevant button on the menu bar or follow the on-screen instructions

4. Pay attention to whether "Enable Shared Calendar Improvements" is turned on. If so, please turn it off and then turn it on again.

Outlook may prompt that it needs to be restarted. Users can restart Outlook according to their needs.

Users can use these two methods to temporarily solve the slow startup and carding of Outlook. Dead question. However, Microsoft plans to provide users with an official fix patch in November to completely solve this problem
