<div>
did you try the suggested repair, or repair tyhe pst file
</div>


<div>
Haven't tried repair. That is going to be a last resort. Outlook runs fine by itself. The jetlag only occurs when it is called by another program.<br />
<br />
No PST. it is connected to a hosted Exchange account.
</div>


<div>
does it also happen with another user account?
</div>


<div>
Right now there is only one user on that computer. I can log in as a different user and test but it will take a while....
</div>


<div>
&gt;&gt; &nbsp;Neither did un-installing and re-installing. &nbsp;&lt;&lt; &nbsp;what did you install?

Whether it is Adobe, Snipping Tool or Sharpdesk. Really no matter what the apps.... when Outlook is called from another program it takes 3, 4 even 5 minutes before Outlook actually pops up once it is called. Brand new computer. I5-8500, 8GB, SSD. Windows 10 Pro so I don't think it is in the computer. Office Home and Business 2019 32-bit. <br />

What could be causing this &quot;jet lag&quot;?
