Hi Mindy,
There has not been any error code #17886 troubles in the past few days. I spoke too soon, users are still getting "Unknown error #17886" in addition to the other errors listed below:
There are several new errors that users have been getting today - including users who hadn't been experiencing any outlook problems in the past. (All computers are now running OS X 10.9 - Outlook version 14.3.9).
"An unknown error has occurred" (# -3210)
"Connection to the server failed or dropped" (# -3253)
"End of the file was reached" (# -17875)
Can you offer any insight of fixes?
