I updated to the latest SM version 15.x on Monday this week. On Thursday this week POP3 started reporting issues via outlook on serval PCs. Not all PCs seem to be affected and this is common for MS Office 2007,2010 and 2013.
I have seen errors 0x80042108 & 0x800CCC90 & 0x800CCC0B,
I first thought it was due to MS updates applied tuesday night but found one PC with the same issue that had no MS updates since 9/2015 (today is Friday 4/15/2016). I then found MS updates were applied on the SM seerver (Win 2008 Std) that were also applied tuesday night as well. I am not using IIS as the web interface.
I have been backing out the server updates (9 total) with no success so far (one left to do).
Has any one else having issues?
