Outlook GUI goes white, not responding

[Benzini00]

Hello everyone,

 

Our users mailboxes are all hosted in Office 365, we're using Office CTR on-premises and have plenty of bandwidth headroom on our WAN connection.

 

Some of our staff members are reporting issues with the Outlook desktop application whereby the Outlook interface intermittently and briefly turns white, the internal frame of the application remains but the content of the folder list, reading pane and items frames are replaced with solid white backgrounds and the application will often report it's 'Not Responding' ... after 30 seconds or so everything returns to normal.

 

It almost feels like Outlook is trying to communicate with Office 365 and when it's unable to do so it drops the content from the internal frames/windows until it can re-establish communication.

 

The affected individuals are mainly using 'cached' mode although a small number are using 'online' mode.

 

There are a number of posts on-line regarding similar behaviour ranging back to Office 2013 but none of them ever result in a consistent or firm solution.

 

Has anyone else experienced this? If so how did you address the issue, what was the cause?

 

Many thanks,

 

Ben
