before trying to move mailbox to a different database, i need to reduce the size.Currently the email box is very hard to work upon, it goes into loop as soon as we open an email. Working on each email itself taking about 10 minutes with such performance moving data from 2012 with each month having an average of 4k to 5k emails is very difficult task.
I don’t think we can move them manually and also I don’t want to take the risk of losing any emails during manual process.
Later, I was able to create a folder in the online archive and then initiated the transfer but in between again the Outlook crashed on my computer. After which I checked the transfer didn’t complete.
As the mailbox has huge amount of emails is there any way I can reduce mailbox size.
