Try to open outlook in safe mode first. Run "outlook.exe /safe" command , if your problem gets solve then remove addins one by one to identify which add in causes issue. If your problem still persist refer this link:

To run outlook in safe mode follow the steps mentioned in here http://www.filerepairtools.com/tips/how-to-run-outlook-in-safe-mode/

Hello,

You should try to open MS Outlook in safe mode and check the status.

To do so: Press Window Key + R >> Type outlook<space>/safe in the Run prompt to open Outlook in safe mode.

If it is working fine in safe mode, then the issue may be caused by the add-ins.

To resolve this:

Open MS Outlook >> File Tab >> Options > Add-ins >> Select Manage COM Add-Ins at the bottom >> click on Go button.

Then uncheck all the add-ins listed there and click OK.

Now, restart MS Outlook in normal mode and check if it opens fine.
