Very, Very Slooooooow Email Synchronization with Outlook 365!

Over the weekend I had to reload Windows 10 Pro and my Office 365. and have had nothing but trouble getting my email account to sync to my computer! I am using IMAP so Outlook only creates a ost file. According to my checking on the web it only uses about 1mb yet the email server is only transferring 50k or so at a time, once and a while and then ends up timing out.

I have wasted many hours trying to get Outlook up and running.

What the heck is going on????

I have been a AT&T customer for many years and don't ever remember this kind of issue with Outlook.

Is it time to look for better service else ware?

Hi Marc,

While I appreciate your reply, the problem finally ended today. It seems my email totaled around 2 gigs and took about 16 hours to download as a .ost file and then to finally stabilize in Outlook.

You might want to let people know this when using Outlook as a email client that it may take this long as it appears to the user as if it's not working.

Keep in mind this only occurs when client is first installed and initialized.

What I finally started to do was watch the file size with Outlook running and monitored ost file size as it downloaded all of the of the folders with contents of a email account.

My internet connection is over 300Mbps so that was not the issue.

It all boils down to how much data you and Yahoo send at a time.

There was many times were pauses of 15-20 minutes occurred between transferring of more data. These delays cause Windows to constantly sit there monitoring for data and in my system would kick in high cooling for CPU.

I would suggest a better system to handle such situations should be considered.

Once the data is download all returned to normal. And again responsive.
