I have been getting the enter network password many, many times a day for a long, long time. It was happening when I was using Outook 2003 then 2007 and now continues with my current 2010 which runs under Win7. I can't be certain but I almost certainly migrated the settings on each occasion. I have intermittently tried to fix it over the years without success. I got 797 hits in the outlook forum but they seem to repeat the same suggestions. Which I have tried but to no avail.
To be clear I have done the following today
Created new profile (this has been done several times in the past) ran scanpst ran /cleanfolders disabled non MS addins set server timeout to 2.5 minutes deleted ....roaming/microsoft/protect done actions in 'troubleshooting tips' done actions in kb290684I
I clearly don't have a problem with the actual password.
Any suggestions/observations will be gratefully received and acted upon.
