Hello!

In our company, we have an Exchange hybrid configuration. On one computer running Outlook 2019, the message "Cannot expand the folder. There is not enough free memory to run this program." appears several times a day. Closing and reopening Outlook resolves the issue temporarily for a few hours.

The email mailbox is large, nearly 10 GB. We have tried the workarounds suggested here, but none of them have worked. (We also tested with very high values for the registry keys.) There are no plugins that could be disabled.

What else can we do? Thank you very much!
