I use Outlook a lot and group all the outlook related tabs together. The following screen capture is the normal view of all my opens tabs:

When I click the send / receive icon at the top left to force a send / receive of outlook, the send/receive window pops up and it is combined with the rest of the outlook windows, as shown below:

Since the send/receive window is much narrower than the normal window of outlook, after the send/receive finishes, the outlook windows becomes very narrow also, as shown below:

I have to manually drag the windows width to original width.

Can you please help me on this?

Thank you very much.
