Outlook 2011 for Mac 14.4.7, yesterday I suddenly started getting error - 17099 "<A> invalid address" on a hosted email account (POP/SMTP) that had been working fine for a long time. For two days I get the error virtually every time Outlook attempts a send/receive "to this email account". No email settings have changed, no recent updates have been applied and my local network/router/devices/etc has not changed. The hosting company says it's not their problem, yet my other (ISP based) email has no such problems. I have fiber/broadband, so my connection speed is excellent. Any thoughts?
