Fix error code 17099 in Outlook Mac 2011/15/16

MS outlook is one of the best and most widely used email client which has a feature to store mails, contacts, appointments, journal, tasks and Notes. There are also many other options available like distributed list, flags, searching of mails, Rules, etc.  which user can apply to these mail objects. With the release of Office for MAC in the year 2011, the popularity of this software was also increased among the mac users. Microsoft kept the interface of the mac version nearly same as of its windows brother except the file type. i.e. in Mac, the default file type is OLM whereas in windows it is PST. Like the PST file, the OLM file also stores all the mail objects (Mails, Contacts, Calendar, Tasks and Notes) on the OSX operating System.

But like the windows version, the mac version also experiences errors and corruption. Your OLM file may corrupt due to following situations

  • If you are using an old version of Outlook
  • Interruption in the middle when you are updating your outlook
  • Virus attack
  • Hard drive failure
  • If you are connected to exchange, then a crash on the exchange can make your OLM file corrupted.

These situations can effect on your OLM files and you will experience an error message “error code 17099” every time when you open Outlook. This happens when the SMTP server is returning a permanent or transient error or an unexpected result code. This error may also appear when you are trying to send mail to a large group, but your ISP provider has set the limit on the number of recipients to which you can send mail at a time.
