Error message: Your IMAP server.....


  • I am getting an annoying repetitive message every time Outlook checks for mail:

    "Your IMAP server wants to alert you to the following: Cannot delete folder with subfolders."

    I am not deleting any folders!  But I get this message many many times a day. I've been through the email accounts to ensure I was not deleting anything.  Please help.

  • Could be that your local copy of your mailbox has become corrupt, in which case the best way to proceed is to re-name the .ost file and let Outlook re-create it from the server. As mentioned here if you're storing anything in your 'this computer only' folder, for instance calendar and contacts, you'll want to export those to a .pst file first otherwise they'll be lost.

  • Hi,

    I agree with what Keith said. Close outlook, rename the imap ost file. Restart Outlook and let it rebuild the data file.

    Best regards,

  • I keep coming to this same post when seeking a solution to this same problem. I do not store "calendar and contacts (or anything) in the 'this computer only' folder." I do not even have a 'this computer only' folder" in that location.
    For my nonprofit and our different programs and sites I have a dozen different email accounts and in that file each one has its own .ost file already. How in the world do I rename them with Outlook having any clue which ones to rebuild and sync with which other ones so they can be rebuilt?

  • If you don't have a 'this computer only' folder then you don't need to worry about that step. That bit is purely to prevent you from losing messages which are only available locally when you rename the .ost, since if they're stored locally they won't be among those messages downloaded when you re-create the ost file.

    If you're trying to rename just one of the files then go into File, Account Settings, Account Settings... and then select the Data Files tab. You'll see a list of all the data files in Outlook and which files relate to which email account. With the relevant mailbox selected you can also click Open File Location to do direct to the relevant folder.

    If you wanted to resync all of the files you could simply rename all of the ost files, at which point Outlook will re-create all of them (with the same name and file paths as before) and resync the content in all of them when Outlook is next started.

  • Oh wow ok, so if I rename each of them with say -12 at the end, Office will just rebuild them upon restart correct?
