Re: WebDav get over quota messages
Hi SnowCash,
I don't think there is really a way around the search.
What you could do is to create a search-folder in the NON_IPM_SUBTREE
portion of the mailbox. This is what ActiveSync does to get changes in the
mailbox.
Kind regards,
Henning Krause

Re: WebDav get over quota messages
Thanks for that.
I'm a bit surprised ActiveSync doesn't use replication (?)
Do you know when/how frequently a search folder is updated? I'd assume it's
updated when it's accessed?
Thanks
