unfortunatly there are a ton of messages to find on the internet that do not resolve my issue.
GPO: download full items
GPO: Cache three months
Exchange365 size: 9080Mb
created days ago: 972
current User OST size: 5Gb (excluding the ost's for shared mailboxes which have diffrent ost files)
new outlook profile, grows to 5Gb in 2 days
find folder size, size is not there
new windows profile
what else can i try to reduce the OST file size as this should only be 840Mb instead of 5Gb.
