I have a few users mailboxes that are much larger than the "safe" size.
As i understand an OST should not be larger than 25GB. I have some users that are close to 50 and 1 or 2 that is over 50. I had to edit the registry to allow the ost to grow larger than 50.
I believe the answer is to let these users use their mailboxes online and Outlook not to cache emails. I don't have experience with this and I want to know what the challenges are if i do disable the caching of emails - specifically search ability of old emails and connectivity external from the office.
Thanks in advance.
