I have someone that wants to add hundreds of other users email accounts to Outlook. We've tried in the past and run into issues with random Outlook errors. Is there any guidance as to how many Exchange accounts Outlook can reasonably handle?
We have disabled cached exchange mode for the remote mailboxes. We have also upgraded his computer so that Windows and Outlook are both 64-bit, along with having 8GB of memory with nothing else installed.
Clearly 1-5 mailboxes work fine, but is there anything official, or any literature that I can show him that shows that it's not designed for that (or maybe that it is).
