I have a fairly large mailbox (5GB) and have many folders and sub-folders. I want to reduce the number of folders and so, I am planning to collapse many sub-folders into the parent folder.
For example, instead of having Travel > Updates, Travel > Airlines, etc., I want to just keep a folder called "Travel".
I typically don't use Outlook on the desktop, I only use Outlook Web App. The Web App has a limit on how many messages I can move at a time.
Is there a way to collapse these folders programmatically? I am afraid a simple solution like Outlook on the desktop may not really work because it will take a long time to sync my 5GB mailbox to the desktop, and then take a long time in moving those messages around. Hence, I am looking for something that can execute on the server itself.
