Hi Lisa, now the user is using New outlook, it has no issue, but he want outlook classic. If i remove profile is this will affect the new outlook also?
Interesting question! I will create a post about that with my latest results. A while back, New Outlook and Outlook Classic did not talk to each other but lately I have seen them working together with accounts. Not with all my clients but on occasion, so I make sure the data is backed up if local and the users have their passwords in case we have to add the accounts back in again on either program.
For your answer: I never remove profiles, I make new ones and leave the old ones in case I need data from it or if the new one fails I can revert back. Just a pro tip there!
Thanks a lot! Let me try to create another profile for Outlook Classic with 50GB and one year data then will update you.
hi Shabin, how did you get the OST to 100 gigs? Outlook Classic only has a limit of 50 gigs, so look at it this way, the server mailbox can have 100+ but Outlook can only really safely view 49 gigs before it expands and most likely will lose functionality in time. When you first setup a new Exchange account in Outlook Classic the default is one year. You can view "all" but if the server has more than 50 gigs, you can turn on in-place archive, then you can view "online" mode more email.
I highly recommend a new profile and download 1 year of data, leave the rest to search. That will give you a better Outlook experience and Outlook should not crash so often.

Hi Lisa, The user has already in-place archive, now i have to create a new profile and it should be 50GB by default right?
Thanks
I would only set the download to be a year, this will keep the Outlook profile running more clean. Easier to set up too! Then everything on the server is searchable and in-place archive will show up at the bottom.
Hi Lisa, Thanks for the reply. 100GB is the OST. How can i set 1year of data while creating new profile. The user has EP2 license. Thanks
Shabin, is the PST or OST 100 gigs? Either one is well beyond the limits of what Outlook can handle. 50 gigs is the limit. I would create a new Outlook profile and only download 1 year of data and that should download a manageable amount of emails/data from the server. Other things that can cause Outlook to crash is doing all the Office updates, Windows updates, checking your AV, firewall, VPN and web filters.
