I get the following message multiple times when starting outlook:

Your IMAP server wants to alert you to the following: 2 That mail is not currently available



I have tried all the suggestions in other threads, like searching for 0 size messages (initially there were none)

and moving all your messages to temp folder and then back to the original folder

which caused all the moved messages to now show a size 0.

• I would like to know how to fix the messages that where moved to the "Temp" folder and back so Outlook 2013 does not continue to report 0 size messages for messages that are definitely not 0 size!
• This happened on a brand new install of 2013, and new import of old AOL mail into outlook using the wizard so everything was setup according to the microsoft default detection of AOL. 
• Also I moved 3gb of old AOL mail onto my local machine in an attempt to eliminate the error. All that did was change "following: 1080" to "following 2"
• Note that this problem appears to be a common complaint with no real solution.
• The correlation of the popup with the "folder [800CCCD2-0-0-560]", which I can't correlate with the folders I see on AOL calls into question whether their is really a bad message or not.
• scanpst.exe was run and does NOT fix this error.  It did however claim to find errors, but did not inform as to their nature.

-> error message doesn't contain enough information to let you find the bad message or folder.

-> no option to "suppress the dialog popup" so you aren't barraged with messages that perhaps should only be displayed in the sync log.

-> there are so many "non-professional" red-herring opinions that you can't find the solution in the forest.

-> could be helpful to have a unique place where only solutions are posted.

I noticed in the sync log these messages which seem to correlate with the above dialog box.  The first log message:

The last recommendation of setting the root folder to Inbox appears to be a bad thing

to do since it makes your sent messages disappear in outlook.  It also has no effect making the sync error go away..



Recommendation "Uninstall the recent updates (KB2837618 or KB2837643)" seems irrelevant since I see no Office/Outlook updates installed on this new s
